Compact, Redundant Potentiometers:
PK 609 Series from FSG

Potentiometric transmitters from FSG's PK 609 series are based onPK 609 a high-resolution resistor element made from conductive plastic, printed on fiber-glass reinforced support material. Designed as ganged potentiometers (triple), they have a maximum active angle of 350°. The intrinsically safe units are suitable for use in applications with explosive atmospheres. For adjustment of the measuring range, the potentiometers can be equipped with short-circuiting tracks, taps and function windings (e.g. according to a sine or cosine function over 360°). With a housing diameter of merely 22 mm and a weight of 15 g, they can be easily integrated into machines and plants even if installation space is limited. Suitable for use at maximum temperatures of 120 °C, potentiometers from the PK 609 series reach a lifetime of 50 million wiper movements. The cost-efficient, low-maintenance units are highly precise and can be adapted for individual applications. In many fields, they therefore still provide an attractive alternative to wear-free but more costly digital components.

The company ELIS PLZEŇ a. s. presents its new generation of the FLOMIC ultrasonic water meters designed to meet most demanding requirements of water-supply plants and network operators, in particular the operational diagnostics of the water piping condition and minimisation of water losses. The FLOMIC FL5024 and FL5044 battery-powered ultrasonic water meters are intended for operational and commercial water flow rate, pressure and consumption measurements in observance of the requirements in standard ČSN EN 14154. The meters include data storage capability and interfaces to data communication systems. These water meters have certification according to MID.
Both meter versions, FLOMIC FL5024 (single-beam) and FLOMIC FL5044 (double-beam) are of a compact design meeting the requirements associated with protection class IP 68. In its standard configuration, the meter provides for measurement and display of the values of instantaneous flow rate in m3/h in the given flow direction and of the total volume of water in m3 passed through the meter sensor since the last resetting of the volume counter. The meter further includes a passive impulse output consisting of an opto-coupler. Additional meter features and accessories available on request include:
    •  design modification for drinking water;
    •  current output 4 to 20mA corresponding to actual flow-rate readings;
    •  instantaneous water pressure measurement and display within the pressure range of 1 to 16 bar and the        measured value indication via a current output 4 to 20mA;
    •  water flow rate and consumption measurements in both flow directions with visual and electronic indication of        the actual flow direction;
    •  power supply via a current loop (battery-free meter operation);
    •  independent storage of all measured values over the period of one minute to one year;
    •  reading of the actual measured values or stored data via optically-insulated USB or RS 232 interface;
    •  using a GSM module, reading of the stored data and transfer of the same to a mobile phone or a plant control        station;
    •  selection of flow rate units: litres/sec. (volume in m3) or gallons/min. (volume in gallons).

The integrated Li battery 3.6V ensures 8-year continuous meter operation (applies to the standard meter configuration). The selected measured quantity including the measurement unit is displayed on an 8-digit LCD unit. The associated push-button is used to select the desired measured quantity: instantaneous flow rate, total flow volume passed in one direction, instantaneous water pressure or total flow volume in the other direction. The meter housing is provided with a special pressure-equalising valve preventing water condensation inside the electronic housing. The associated sockets and cables are of the same IP 68 design.
The ultrasonic probe is accommodated in a casting made of ductile iron with flanges according to the customer specifications (ČSN EN, ANSI, JIS, AS). All types of the ultrasonic probe may have pressure sensors fitted.

INFRARED IMAGING: Infrared imaging system increases boiler efficiency

http://www.vision-systems.com/libs/cq/ui/resources/0.gifIn South Africa most of the electricity is generated from coal-fired boilers. Efficient power production requires plant operators to monitor boiler tubes and slag deposits that prevent boilers from running at peak efficiency. Proactively maintaining boilers helps coal plant operators to improve boiler uptime by reducing the number of manual cleaning cycles and decreasing tube erosion that may be caused by excessive cleaning.
"In the past," says Lenny Shaver, director of business development with LumaSense Technologies (Santa Clara, CA, USA), "this process was performed manually by operators who viewed the combustion process and internal components of the boiler through observation ports. Not only is this not accurate or repeatable, it is also hazardous since boiler temperatures are often as high as 1100 °C." What makes it even more complicated is that the human eye is sensitive to light from between 400 and 700 μm, so boiler tubes cannot be accurately visualized during the combustion process.
To overcome these problems, LumaSense has developed a turnkey system known as BoilerSpection for continuous infrared (IR) imaging inside the boilers (see figure). The system uses a vanadium oxide-based, 320 × 240-pixel microbolometer camera with 0.08-K sensitivity, equipped with a 3.9-μm bandpass filter, to image the boiler tubes during the combustion process.


LumaSense's BoilerSpection system uses infrared imaging to continuously monitor boiler tubes at a coal-powered plant during the combustion process

LumaSense's BoilerSpection system uses infrared imaging to continuously monitor boiler tubes at a coal-powered plant during the combustion process.

Camera systemsOf course, manufacturing a camera to operate in such harsh environments is not a trivial task. The imaging system is fitted with a 16-in. borescope that is placed through the observation port of the furnace. The camera system is then mounted to this external port. Cooled air is passed BoilerSpection installedthrough the borescope and the camera housing to lower the temperature of both the lens and camera. This also allows the lens and camera system to be purged of any contaminants that may adversely affect the system's operation.
Images captured at up to 30 frames/s are transferred either digitally over an Ethernet interface to a host PC or via an NTSC interface to a colour monitor. In this way, images can be processed and displayed on the host PC and simultaneously viewed in real time. After images are transferred to the host PC, they are processed to determine specific characteristics.
Infrared image To check the buildup of ash and slag, for example, specific regions of interest (ROIs) within each image can be programmed so the operator can monitor how the temperature within them changes over time. Based on these comparisons, the system can be used to automatically alert an operator, trigger an alarm, or control cleaning equipment on the boiler.
By monitoring these images over a specific time period, the system also provides historical data of how the coal burning process is performing, which helps to maximize the efficiency of the process. Historical data are also crucial for evaluating the effect of other changes to the process, such as new fuel sources or maintenance to the burners or coal pulverisers.
To further extend access to images captured by the IR cameras, the host PC software broadcasts the images as streaming JPEGs to a web page. Any user that is granted access on the plan network can view the images using a web browser. Access is controlled by standard Internet Information Services (IIS) tools that the plant's IT department controls.
The system is already being used by a number of coal-powered facilities. One such facility, Alabama Power's Miller Steam Plant, has deployed numerous cameras to monitor two of its four 720-MW boilers. The 12-stories-tall, 60-ft-wide boilers each use six BoilerSpection cameras to monitor the combustion process at various locations.
Prior to using BoilerSpection, the Alabama plant's operators estimate they performed approximately 51 de-slags on the boilers in 2010. During a six-month period using the BoilerSpection system, only 12 of these processes were performed, resulting in huge savings to the site. The plant is now planning to outfit its remaining two boilers with the vision system.

Bridge into the digital future
By EK Springer, Mecosa

Process measuring sensors with integrated transmitter improve the signal quality and calibration ‘comfort’.

With the incorporation of the ARC-system into its process measuring sensors, a bridge has been created into the digital future for pH-, dissolved oxygen-, and conductivity measurements. Three application concepts – from standard single loop operation, via analogue interfaces up to complex field bus linkage – take the different requirements of various customers into account: biotech-laboratory and production, as well as plant-contractors. All concepts feature the same: the external transmitter is removed – and therefore the weakest link in signal transmission is removed.

Precision and reliability are the mark of Hamilton. Numerous researchers still depend on the micro-litre syringes, which the company founder, Clark Hamilton, invented 60 years ago. These syringes still have their place in the company portfolio. Precision plays a vital part in sensor development. No compromise on accuracy can be allowed with the pH-, dissolved oxygen- or conductivity value during these measurements in their numerous applications in biotechnology production. The demand is first class quality. In this respect Dr Gleb Zhylyak, production manager for intelligent sensor innovation, and his team of developers, represents and continues the tradition of the company’s founder and with their latest efforts expand this competence. With the development of the optical sensors Visiferm-DO (dissolved oxygen) the company has changed from a traditional sensor manufacturer to a measuring system producer.

More intelligence into the sensor
‘More intelligence into the sensor’ is a trend which is ongoing – and has been for many years. The company which the author represents follows this trend in process analytics with intelligent sensors having integrated electronic circuitry; Visiferm-DO sensors as the forerunners. Incorporated into the well-known 12 mm-pH-sensor-design of the new DO sensors, are microprocessor, analogue and digital interface (Modbus) and a so-called ECS-Interface (Electrochemical-Sensor-Interface) for direct connection to a standard transmitter installed directly into the sensor shaft. The sensor can be connected directly – analogue or digital – to the PLC. The intermediate connection of a transmitter is no longer required. The sensor does not just supply a current signal but also supplies process-relevant information. Visiferm-DO does not measure electrochemically, it measures optically and utilises the phase-shift of light on a luminophore. This phase-shift depends on the oxygen concentration of the measured medium.ARC - a new system

Figure 1: More intelligence into the sensor: the transmitter is directly installed within the sensor shaft of pH-, dissolved oxygen- and conductivity electrodes. The service unit ARC-View can communicate, if so desired, wireless with the sensors.
Miniaturising
The next step of the development: to integrate the new technology, proven with Visiferm-DO, into pH- and conductivity-sensors under the protected name ‘ARC’. Around this family of intelligent ARC-sensors emerges a periphery of new products, i.e. control and maintenance or service instruments. The technology drive came from the miniaturising of electronics, which was geometrically necessary until a transmitter could be integrated into a process sensor. Work is carried out with renowned research institutes in order to push miniaturising to its limits. On the other hand the market demands sensors which do not just supply an electrical signal, but the relevant process data – which is quite possible with a number of field instruments. The result of this is that the manufacturer experiences a transformation, from a sensor supplier to an information provider.

Vital, Versa, Vision
Not only for the manufacturer, but also for the user, the integrated intelligence, according to ARC, corresponds to a paradigm change. The sensor is now an independent instrument which evaluates the data for process control. The advantages depend very strongly on the application method of the user and his or her concrete demands. Three different concepts are based on typical applications: Vital, Versa and Vision. In these concepts the intelligence of the conductivity-, dissolved oxygen- or pH-sensors of the ARC-family, and their associated instruments, are utilised quite differently.ARC Vital

ARC VisionFigure 4: ARC-Vision: High-end application via Modbus connection and wireless sensor monitoring.

Vital
Vital, according to  Dr Gleb Zhylyak, is the simplest application and is used if the customer requires only reliable measuring values. He can achieve these by using an ARC-sensor without any additional instruments. One standard cable carrying the 4 -20 mA signal to the PLC and the job is done. That is how the vital function of a process-analytic-sensor, the measurement of pH-, conductivity- or dissolved oxygen-concentration can be realised – and logically, the application is therefore called ‘Vital’.

The critical link has always been the transition from the electrochemical sensor to the transmitter; cable and contact quality strongly influence the quality and reliability of the indicated measuring result. An outstanding sensor quality may very quickly be destroyed. Typical ‘Vital-ARC-users’ benefit from the better quality of the measuring value, especially in the research laboratory.

ARC-View
The functionality of the transmitter is better realised within the sensor, the weak spot of the signal transfer to the transmitter is eliminated and the electronics is perfectly matched to the respective measuring task of the sensor. But what about the functionality of the transmitter, the human-machine interface with display and operational panel? In principle all information which the ARC-sensor supplies can be accessed via the process control system. In simple cases diagnostic values may be called up from the PLC and calibration can also be performed via the PLC. If an operator needs to see measured- or diagnostic values, or wants to perform a calibration at the point of measurement, he can make use of the service or maintenance instrument ‘ARC View’. The ARC-View instrument is also available in a fixed-installed field-housing having IP 67 protection, or as a desktop version. One ARC-View service instrument can communicate with up to 31 ARC sensors simultaneously, e.g. it is easily possible to compare the quality of two similar sensors.

ARC-Versa
This is an example of an application which is included in ‘ARC-Versa’, the second typical concept: Applications within the scope of ‘skid-installations’ (medium-size bio-reactors) where several sensors are mounted within one measuring system. At the same time single sensors can be addressed, even wireless, via the maintenance tool ARC-View. For this, a wireless-adaptor may also be installed at the sensor-head at a later stage.

ARC-Vision
‘ARC-Vision’ stands for the user’s high-end-application, where the complete equipment of one or more plants of his factory, with intelligent sensors, is necessary. These are then connected via a Modbus. Calibration can be effected on- or off-line. ARC-View enables the wireless sensor management which can of course also be performed via the PLC. Fully digital technology is offered – with the possibility to address all sensors completely digitally. This could be the system of the future as digital communications are increasingly being utilised with notable success.

High-end-application with Bus connectivity
The customer benefits from the robust digital technology as well as from the shorter configuration time and the reduction of operator errors. Eventually this will have a positive effect on the profitability of the company.

With the three-step concept Vital – Versa – Vision, the different needs of the end-users can be met. Customers who do not allow a fully digital communication in their plants, still use the widely accepted 4 – 20 mA control system. For them the ARC-Versa is a practical interim-step to fully digital technology which will succeed in the medium-term. ARC-Vision, however, is the concept for the one who wants to take the step into the future… today – in all cases where users start with new plants or upgrade old ones and parting from the analogue technology. Basic equipment with Vital, first steps into the digital future with Versa or the full digital technology with Vision – all this is justifiable. The intention, with ARC, is to build a bridge between different approaches.

First tests
The ARC concept was introduced at the Achema, May 2009, as a preview with a positive response. There were many 'early adopters' who were prepared to test these instruments before the market introduction. The first beta-tests were performed in September 2009 with excellent results. Price-wise the whole ARC concept is attractive. Typical applications have been calculated, e.g. the deployment in fermentation, where sensors are exchanged on a routine basis in order to avoid any quality risks. The total calculation with ARC-sensors paid off very well against the use of conventional components. The final price-scheme was announced at the official launch in December 2009.

In the company’s view, it would not be of much use if one achieves technologically advances in signal conditioning, yet the sensors used in the fermentation processes are not of a high grade. The quality of the signal is produced within the sensor head. The basic sensor programme for pH, conductivity and dissolved oxygen, offered over many years, will not change. There is a special sensor for each possible application. The pH electrodes of the Easyferm-Plus series, also available with the new inductive Memosens technology, and the Easyferm-Food electrodes, have been optimised for the biotech production.

Pre-calibration
The feasibility of the pre-calibration which was made possible through the integration of the transmitter functions is impressive. Furthermore, a quality control for each sensor is provided – through this ‘maintenance on demand’ can be realised and the requirements on the operator is reduced to the essential. The sensor knows everything about itself. But what information does it transmit? The first aim of our concept was to provide a user-friendly tool. The main parameters – the measuring value and the temperature – are primarily indicated, together with a sensor status signal in traffic-light colours – green for all is okay, yellow warns he user that something has to be done, and red signals an error situation. The easy definable access control to the different user levels supports the fault-free operation.

Conclusion
Already in the early stage of development Hamilton has acquired bio-reactor manufacturer Infors HT as a test-partner. The result was shown at the Achema 2009 on two bio-reactor-systems – Labfors 4 and Techfors. In these the analogue sensors for the measurement of pH and dissolved oxygen were exchanged with ARC-sensors (Easyferm-Plus ARC, Visiferm DO). The bioreactors fermentation control system now receives the measuring values directly from the sensors. In the next step the diagnostic-functionality will be integrated within the preventive maintenance. Hamilton’s partners at Infors HT took the chance to adopt an intelligent fermenter control. Soon they will completely transpose the Vision-concept and with it realise a recognisable streamlining of their control system with full functionality of the measuring technology.

NIR (Near Infraread) Measurement and Control in Snack Foods – Moisture, Fat, Protein & Colour

NIR transmitter MCT 360Near Infrared (NIR) Measurement and Control is extremely important in the production of potato chips and snack foods, moisture does not only impact the taste, but also the texture and shelf-life. Oil measurement is required for labelling, and is needed to ensure consistency in the flavour of the chips, but also can provide important process information concerning the replacement of slicing knives.
Several food-grade options are available for the MCT 330SF dependent upon the ambient temperature and space constraints at the point of installation. Typical measurement locations on snack food lines are at the exit of the fryer, oven or seasoning drum where any combination of moisture, oil, temperature and colour can be measured. If high temperature is not a limiting factor or vortex cooling is readily available, the MCT 360, a truly smart sensor with all processing capability within the head is a cost effective option.
The MCT 660 is a multi-constituent non contact bench-top Near Infrared Transmitter, in addition to moisture it can be configured to measure fat, protein and colour in many materials. The majority of products can simply be taken from production and analysed “as-is”, results can be obtained in seconds.

Radiometric Level Measurements
Nuclear Level Gauge Nowadays, there are many possibilities for continuous monitoring of level. However, most of the measuring technologies are limited when it comes to challenging requirements and extreme process conditions. In those cases one measuring technique stands out from the others – the radiometric technology.
Radiometric level measurements are based on the principle of transmission. Working in a non-contacting way, the equipment doesn`t have to be installed inside the vessel; emitter and receiver are mounted on the external wall. Neither high temperatures, nor dust, pressure or chemical properties of the material have an impact on the measuring performance. Even abrasion caused by bulk materials is negligible. Those systems are maintenance-free and offer a remarkably long operation lifetime.
For more than 50 years, Berthold Technologies has been specializing in this measuring technology and the product range of the company contains plenty of measuring solutions for continuous level measurements. From rod sources to rod detectors – depending on the customer’s requirements and applications, the optimum measuring solution is chosen and dimensioned corresponding to the individual situation. As a matter of course, we also provide a collateral support in administrative matters, product-related workshops and start-ups of our instruments.

VariTrans A 21000 P0 from Knick – the only standard signal isolator with a universal power supply in a 6 mm housing

VariTrans A 21000 P0 VariTrans A 21000 P0 from Knick is an extremely compact standard signal transmitter with three-port isolation in a space-saving 6 mm housing. Calibrated range selection makes time consuming parameter setting and adjusting unnecessary. The only standard signal isolator with an integrated universal power supply for international use, the device can be operated with 24…110 V DC supply voltages as well as 110…230 V AC. Although the modular housing is only 6 mm wide, the new VariTrans amplifier meets the high requirements regarding personnel and plant safety with protective separation according to EN 61140 with a maximum operating voltage of 300 V. The test voltage is 2.5 kV AC. The VariTrans A 21000 P0 with protective separation and a universal power supply can be fitted into a 6 mm housing because it emits very little heat. Since the devices do not require ventilation space when rail-mounted, control cabinets can be packed very densely. The low self-heating also leads to an extremely long life span. The average mean time between failures (MTBF) is 280 years. Knick provides a five-year warranty for the VariTrans A 21000 P0.

Seawater-proof multi-turn encoders with digital bus interfaces

Multi-turn encoderAt this year's Hannover Messe exhibition, measuring and sensor technology expert FSG will present the new MH4096-PB/CAN-1023 series of high-resolution heavy duty encoders. The devices register the rotation angle and speed with a maximum resolution of 12 Bit over 360°, and can cover up to 4,096 revolutions in multi-turn mode. The encoders' contact-free measuring system is based on integrated Hall sensors which register changes in the field of the permanent magnets and transform them into digital signals. Thereby, position values are provided directly after activation, requiring no reference runs after power failure. Thanks to a robust, seawater-proof aluminum housing with a chemically nickel-plated special coating, the encoders withstand even difficult conditions in rugged environments. They are suited for a -40°C...+85 °C temperature range and provide IP68 protection on the housing side and IP67 on the shaft side. A typical application is position detection on ships or in offshore and outdoor applications. The encoders provide angle and speed data either via a Profibus or via a CANopen interface. DIP switches in the terminal compartment at the back of the encoder allow users to assign addresses and activate additional bus terminators. The electrical connection is established via three stainless steel cable glands.

The analyzers, which feature a 12.5 mm wide modular housing, are compatible with all Memosens sensors – pH glass sensors, ISFET and oxygen sensors, conductivity sensors with two or four electrodes, and electrodeless sensors. They can be easily configured via a DIP switch.

The measured process value and the temperature can be transmitted to all common PLCs as floating signals via two standard signal current outputs. MemoRail is available with two power supply types. A 24 V DC model can be connected either directly or via DIN rail bus, and a VariPower model can be operated at 90...230 V AC/DC. In addition to MemoRail, Knick offers an assortment of Memosens components including MemoSuite, a software tool for calibration, diagnosis, and documentation, and the PortaSim simulator. Knick’s wide range of Memosens sensors covers virtually all possible applications. Knick provides a five-year warranty.

About Memosens

The key benefit of inductive transmission of measuring data and supply voltage lies in the easy handling of the sensors in rugged environments. With conventional sensor technology, various factors such as humidity, corrosion, and mineral deposits at the contacts can distort the measured values. Moreover, too long or unsuitable cables and insufficient galvanic isolation can result in further errors. The inductive Memosens plug system allows for contact-free transmission of digitalized measurements from the sensor to the analyzer. Process values and sensor-related data can be stored and analyzed directly in the sensor. Moreover, perfect galvanic isolation makes expensive sensors with a solution ground or additional equipotential bonding electrodes unnecessary. Memosens technology significantly improves measurement quality while at the same time minimizing maintenance costs. Pre-calibrated Memosens sensors last up to 40 % longer than conventional products, and reduce process downtimes.

10 Selectable Gases on Mass Flow Meter

Bronkhorst High-Tech BV, specialists in low flow measurement and control, has upgraded their series of MASS-VIEW® flow meters with three additional gases. Now the user can easily select one out of ten pre-installed gases - Air, N2, O2, Ar, CO, CO2, N2O, CH4, C3H8 or C4H10 - which eliminates the need to recalibrate for different gases. Recently the product line has already been extended with models for Hydrogen and Helium. Besides the selection of gases, the user can switch between four different flow ranges. The instruments are suitable for flow rates from 0.01 to 200 ln/min (Air-equivalent), offering an accuracy of ±2% RD if the flow is higher than 50% of it’s maximum full scale and ±1% RD plus ±0.5% FS on lower flows.Mass-View meter The maximum operating pressure for the instruments is 10 bar(g) or 150 psi(g).

MASS-VIEW® flow meters distinguish themselves by their direct local readout with OLED (Organic Light Emitting Diode) technology, indicating the actual gas flow (in figures and as bar graph), clearly visible from virtually any angle and free from parallax error. The display also shows the flow unit, gas type and totalised flow. As an option, the thermal mass flow meter can be equipped with built-in needle valve for flow control duties. MASS-VIEW® was designed to mimic the straightforward features and vertical format of the VA meter, but with the considerable added benefits of an electronic output signal, high measuring accuracy, virtual independence from gas temperature and pressure variations and inherently safe construction, with no fragile glass components in the flow path.

Power consumption is low and mechanical process connections are fitted for straightforward VA meter replacement. Alarm settings and the selection of pre-installed gases and flow ranges are accessed via a user-friendly menu, using a 4-way navigation button mounted on the front plate. An analogue output signal enables data logging against various parameters and full accountability of gas flow, such as for shared ring main applications.

Moisture Measurement on Belt Conveyor Systems
moisture measurement A new moisture measurement system has been introduced by Berthold Technologies, specifically developed for the measurement of bulk materials, the Micro-Polar II (LB 567).
It provides on-line monitoring on conveyor belts or chutes and can be easily installed at existing plants. The microwave based measurement operates completely without contact. The components are not exposed to any wear and tear as the emitting antenna is mounted below and the receiving antenna is mounted above the conveyor belt. The system provides representative results by the penetration of all material layers. Due to technical improvements in frequency and frequency range, new opportunities have become available for applications, which had been restricted in terms of bulk density or particle size. Using the new system, even high bulk layers can be penetrated due to the increased dynamics. The multi-frequency technology used ensures a stable and reliable measurement as several values are measured for different individual frequencies. When varying bulk heights occur, bulk height compensation is possible.

Monitoring Water Content in Dairy Products
Micropolar For reasons of quality and regulation, the water content of dairy products must not exceed a specific value. In order to ensure constant product quality, the measuring system LB 566 Micro-Polar from BERTHOLD TECHNOLOGIES is used to monitor the water content or the dry substance during the production process. The microwave based measurement provides continuous and real-time measuring data in a wide range of dairy products, like butter, yoghurt, cream cheese and many more. Subsequently, trends in water content or dry substance can be identified at an early stage of production and corrected on time, leading to a significant increase in efficiency.
Micro-Polar provides highly accurate measuring results and is proven to work extremely reliable for many years. The measurement is completely non intrusive and not affected by colour, viscosity or non-homogeneity of the measured product – maintenance is not required.

Radiometric Measurements of Super-latives

In the area of radiometric measurement technology the trend is heading towards lowest possible source activities. Berthold Technologies is pioneering these developments. With its state of the art Super-Sens, the company provides the worldwide most sensitive radiometric detector for measuring point level, continuous level and density, setting new standards in source limitations. Compared to common detectors, the source activity can be reduced by 70-95% when using the Super-Sens detector. As an example the density measurement on a dredging application can be taken, where a source activity of 185 GBq was required in the past to solve the measurement task. By switching to Super-Sens technique, the source size in this application was reduced to 5.5 GBq, which is equivalent to a factor of 34.
super sens The Super-Sens is primarily used when vessels or pipelines with large diameter or high wall thicknesses have to be penetrated. Furthermore, the Super-Sens is the preferred solution when it comes to source exchanges, because already existing sources can be used considerably longer when a Super-Sens detector is installed. An up-coming source exchange can therefore be postponed by several years.
The unique, high sensitivity of the Super-Sens is not an exclusive result of the large scintillation volume (150x150mm), but is significantly determined by an extra shielding, which nearly covers the complete scintillator and protects it from interference of natural background radiation. The Super-Sens is available with separate evaluation unit, with HART or with fieldbus interfaces (Profibus PA, Fieldbus Foundation) and includes all common explosion protection classes.
Since its foundation 61years ago, Berthold Technologies specializes in radiometric measurement technology. The measuring solutions are ideally adjusted to your application and source sizes are calculated individually. We will gladly find out, what specific benefits the Super-Sens could bring for your measuring task. Therefore, please send us your application details.

Measuring Length, Tilt Angle and Speed: Multi-Purpose Cable Drums from FSG
Depending on the model, the robust cable drum series WL and L from FSG serve to measure length, speed and/or tilt angles. The units can be used for the measurement of telescopic arms and booms in cranes and lifting platforms or for controlling stage constructions in event technology applications. Moreover, users can also transfer supply voltage and measuring data via the measuring cable.
cable drum The angle is measured by a high-resolution micro-electromechanical inclination measuring system. In the standard version, it supplies a current or a voltage output signal. The length measurement is carried out by means of the draw-wire principle with a multi-core measuring cable, which is wound in one or several layers on a cable drum equipped with a return spring. In models with large measuring lengths, a spindle roller guide ensures that layers are wound exactly on top of each other in case of multi-layered cable windings. The number of length-proportional drum rotations is measured e.g. by a magnetic angle sensor which is equipped with a voltage or current output. The length and inclination values can alternatively be measured by outwardly identical cable drum models with digital sensor systems, and read out by means of a CANopen interface. FSG also supplies these devices as redundant versions for safety-relevant applications, e.g. SIL 2 according to IEC 61508. Measured data and control signals are transmitted via the cable cores of the measuring cable, which are gripped by a 12- to 26-pole slip ring body and bounded to terminal strips. A completely closed aluminium cast housing ensures IP65 protection. Users can choose between various models with measuring lengths up to 56 m and a measuring accuracy between 0.3 and 2%.
At this year's Bauma exhibition, FSG also presented the new, modular KT cable drum series which includes models with maximum measuring lengths of 100 m. These cost-efficient units can be modified with additions and ensure a high measuring accuracy. They provide either digital or analog output signals and are also available as models for safety-relevant applications.

Transformer Winding Hot Spot Temperature Measurement
hot spot Through the years that LumaSense (formerly Luxtron) have been dealing with transformers, it is clear that the most important  parameter to measure on a transformer is the temperature. Transformer life is dependent upon the life of the insulating paper in the transformer.
The insulating paper life is dependent upon the temperature it is exposed to. The Winding Hot Spot is the highest temperature area in the transformer based on flux leakage from the windings, so naturally this makes the paper in this location the weakest and most susceptible to failure by over temperature conditions. That is why it is so critical to know exactly what this temperature is.
Historically, the way this has been done is by using WTI (Winding Temperature Indicator) instruments (gauges on the transformer). This method is only a simulation. It is not accurate. These instruments base their simulated reading on the top oil temperature and on a CT (Current Transformer) connected to one of the phases that heats an external oil bath to a temperature that is supposed to be indicative of the winding hot spot. WTI instruments typically do not take into account cooling fans running, oil circulation pumps, etc. and have a significant lag time to give a response (approximately 4 hours). Our experience has shown up to a 20°C difference between what the temperature actually is in the transformer and what the simulated gauge reading is.
LumaSense (formerly Luxtron) has been measuring winding hot spots with fibre optics for over 25 years. We have been installed in over 3,000 transformers globally and we currently work with over 85 different manufacturing sites around the world. We were the pioneers of the fibre optic temperature measurement. With this experience, we have learned through the years how to make a robust, solid system. Today, we have over a 99% success rate in installing fibre optics without any breakage. We provide global support and training to all transformer manufacturers to ensure fibre optics are installed quickly and correctly. We have also reduced our pricing of fibre optics by 75% for a system since the early days. And, we have transformers operating for 25 years without any issues and never requiring any calibration. All across the globe, the transformer manufacturers are seeing more and more requests for fibre optics to be used in transformers. This means after 25 years, the technology is finally being accepted as a norm.
So, why should a you use a LumaSense fibre optic temperature measurement system?

  1. Design verification on the transformers by measuring exact temperatures during a heat run or type test and comparing to calculated design values

Measurement of Coke Drum Level
lb 490 Monitoring the level of coke drum bottoms in a delayed coker is among the most important processes in a refinery. High temperature and foam, extensive caking as well as high-pressure water jet demonstrate the unfavourable measuring conditions dominating this application. The radiometric level measurement employing the “LB 490 Tower-Sens” detector from our principals BERTHOLD Technologies, has proven to be a reliable and cost-effective solution that will withstand this tough environment. It provides a continuous measurement, monitoring the foam as well as the coke level in the drum online and very accurately. All components of the measuring system are mounted on the outer wall of the coke drum and are therefore not affected by the aggressive processes inside.
The Tower-Sens utilises a detector length up to 8 m and can even be mounted in a cascaded fashion to deal with the long measuring ranges of a coke drum. Due to BERTHOLD Technologies patented ageing and temperature compensation, the system provides stable and reliable measuring results during the entire operation. The precise monitoring of the coke drum processes enables an optimum utilisation of the coke drum capacity, reduced cycle times, efficient use of anti-foam agent and of course overflow protection.

New Indusens Pressure Transmitter
A pressure transmitter is an electronic pressure instrument that transforms the actual process pressure into an electrical signal with ceramics or piezo-resistive sensors. The signal is proportional to the actual process pressure and changes according to the process pressure change. Output signals could be either voltage or current and are used for controlling processes or for archiving process data. The new "Indusens" pressure transmitters are used for the industrial pressure measurement of liquid, gaseous, and also for crystallising and highly viscousindusens transmitter media, depending on models suitable for hygienic process or petrochemical applications.

The features of these new transmitters include the following:

HAMILTON Unveils ARC Sensor Technology
ARC Sensors provide a robust, direct, and standard interface to PLC
ARC system HAMILTON Company, a world leader in fluid measurement, has announced the Hamilton ARC concept, a new sensor family for process control that includes pH, dissolved oxygen and conductivity measurements.
More than simply sensors, ARC Sensors are the complete solution: innovative premium quality sensors with a robust, direct, and standard interface to the PLC. Hamilton ARC Sensors send an analytical signal directly to an analog process control system while delivering at the same time the power of digital sensor management.
Bruno Waller, Director of Sales Laboratory and Sensors at HAMILTON comments: “With ARC Sensors process downtimes are minimized. The digital connection plus the on-board processor and memory built into every ARC Sensor means they can be pre-calibrated and configured in the lab. Due to the time-saving features for sensor operation and maintenance, costs and opportunity for human errors are drastically reduced.”
Classic sensors produce weak, temperamental signals that require a separate transmitter to amplify the signal before connecting to the process control system. With ARC Sensors a technology has been developed that replaces the need for transmitters. The ARC Sensor’s built-in electronics convert the low amperage measurement signal and enables several unique sensor functions. Apart from the direct analog connectivity, ARC Sensors offer a digital connection that delivers superior data integrity, increased productivity and longer life cycles. ARC Sensors are far less prone to interruption in challenging production environments than classical sensors.
ARC Sensors are available with both standard analog (4-20mA) and digital ModBus interfaces built-in and supported directly from the sensor itself.

FLOMIC, a New Battery-powered Ultrasonic Water Meter.
Flomic
The new ultrasonic flow meters of the FLOMIC type series represent a state-of-the-art solution in water consumption measurement. Apart from water volume passed through the meter sensor, the FLOMIC meters can also measure instantaneous flow rate, maximum and minimum flow rates over specified periods of time and pressure in the water-supply piping. The FLOMIC meters include internal memory units used to store all measured data available to the network operators not only for the water consumption monitoring purposes, but also for identification of the network status and localisation of any leaks or defective network functions.
The battery-powered ultrasonic water meters of the FLOMIC type series have been developed in response to the requirements of potential customers who need a reliable system for monitoring the key parameters of their water-supply networks. While offering the advantage of several functions combined in a single piece of equipment, application of the FLOMIC water meter permits reduction of investment costs per metering location, as well as lower costs of operational maintenance, control, communication and data transfer, if required. Among the advantages of the FLOMIC water meters are:

Thanks to its in-built power source, the meter can be used even at locations where no external electric power network is available, such as locations between communities or uninhabited or generally inaccessible places. Given that, the operator still has to resolve the problem of data collection and processing.
In this respect, an ideal solution for any far-off place is the use of the a mobile-phone GSM network. At present the GSM-signal coverage is almost complete and both the acquisition costs of the necessary equipment and operation tariffs are sufficiently low to justify this solution in comparison with construction of own independent radio-wave or wire transfer systems for the purposes of data or meter-output signal communication.

Utilisation of a GSM Network for Data Transfer from the FLOMIC Ultrasonic Water Meters Manufactured by ELIS PLZEŇ a.s.
Utilisation of a GSM network for data transfer from the FLOMIC ultrasonic water meters manufactured by ELIS PLZEN a.s.
Reliable monitoring of the operational conditions in water supply networks at reasonably low investment and operational costs is undoubtedly a wish of all water-supply operators. However, increasing numbers of measuring locations and demands on quality of the collected data necessitate advanced technical solutions where “manual” data reading becomes unsupportable both in terms of speed or frequency and running costs. Higher reliability of data transfer and cost cuts can be achieved by application of systems including wireless data transfer modules making possible easy and inexpensive monitoring of water-supply networks with automated data-reading without physical presence of the company staff. This article describes an advanced technical solution of a metering location using a FLOMIC water meter and data transfer via a GSM network.
The FLOMIC and GSM-module functions
The GSM module is now offered as an accessory of the FLOMIC water meter. It has been designed to ensure data transfer from the measuring point to the operator station via a GSM network at minimum operational costs. The module is powered by a battery with a long lifetime so that it can be used at measuring locations with no alternative electric power source.
The GSM module co-operates with the FLOMIC meter in that it reads at specified times the measured data from the memory unit, rearranges them into a suitable format and sends them via a GSM network to the associated database server. The data format has been selected so that the volume of data transferred be as small as possible and the transfer costs be kept at the lowest level.
From the database server, the data are then sent to the customer station in the CSV format. The final data processing is dictated by the customer needs. Using a table processor, the data can be visualised in the form of a graph or table, or they can be communicated to a superior information system (control station) to be eventually included into comprehensive operational reports on the whole water-supply network.
data diagramme With daily data reading and transfer using a GSM network, the operational costs per one measuring point, depending on the choice of tariff and mobile-phone operator, may amount to several CZK. If compared with the standard monthly “manual” reading of the data at various measuring locations, the operational costs of a communication system using GSM will be significantly lower than the aggregate costs of staff time, fuel and depreciation of service vehicle in the case of “manual” data collection.
Apart from transferring packages of measured data, the GSM module may be used to send SMSs and/or notify the operator of specific operational conditions. The transferred data may further include information on the GSM signal level in the given location, condition of the meter batteries and similar things.
If correctly used, the FLOMIC water meter in combination with a GSM module may bring to the operator detailed information on the condition and/or behaviour of the water-supply network and, at the same time, decrease the operational costs normally associated with personal inspections and data collection at far-off locations. The GSM module may further facilitate reporting of selected irregular or emergency conditions such as flooding of the measuring pits, disturbance at the network facilities or similar events.
The FLOMIC battery-powered ultrasonic water meters in combination with a GSM module ensure high measurement reliability, operator comfort and high speed of data transfer at very low running costs. The FLOMIC water meters are available in sizes DN 32 through to DN 300, and they can be designed as compact devices or with remote electronic unit and protection class up to IP68. The meters have been certified for use in drinking-water supply systems, and can serve the purpose of invoicing meters.

MECOSA Demonstrates the Future of Sensor Technology
Arc vitalArc versaArc vision On Wednesday, 27th of January 2010, MECOSA (Pty) Ltd launched the HAMILTON ARC System, a revolution in sensor technology. HAMILTON is an American Company with Research and Production Facilities in the USA and Switzerland. Their analytical sensor development and manufacturing takes place in Bonaduz, a small town in the Swiss Alps.
Dr. Andreas Müller, the head of sensor development at HAMILTON, came over to introduce and present the innovative ARC Sensor System at the Benvenuto Conference & Training Centre in Kelland, Johannesburg.
The visitors were welcomed by Henning Springer, Managing Director of MECOSA (Pty) Ltd in true South African tradition by blowing the Vuvuzela. Thereafter the Chairman Erich K. Springer gave a short introduction of the company MECOSA.
Dr. Müller then explained the ARC System to the visitors and calls it a “Bridge between process sensors and the process control system”.  Hamilton manufactures analytical sensors for pH, redox, conductivity and dissolved oxygen measurements. In the ARC sensors the functionality of a traditional transmitter has been replaced by a microprocessor integrated in the sensor shaft. The output includes a conventional dual 4 – 20 mA signal and a digital networking signal. A wireless sensor management via a handheld station includes sensor set-up, on- or offline calibration, fault-finding and data monitoring. ARC sensors’ built-in direct connectivity to the PLC means no more  weak and sensitive signals and no in-between transmitter.
After the ARC presentation a short hands-on session was provided to give the visitors a closer look and a first experience of the ARC.
