The OTT RLS (radar level sensor) is a radar sensor for non-contact water level measurements at surface waters. The sensor uses impulse-radar technology to determine the water level.

The RLS is mounted above the water surface e.g.: at bridges or auxilliary constructions. Its solid, relatively light and water-proof housing is easy to install. Its extremely low energy consumption (active: <12mA @12V), the large power supply range and standardized interfaces make the OTT RLS very flexible for different of applications.

The RLS covers a measurement range of up to 35m. It is specifically designed for the use in open air locations that have no requirement for mains power supply. The special flat antenna design construction and its minimal energy consumption makes the OTT RLS a economical, practical and reliable alternative to conventional level gauges.

The OTT ADC (Portable Acoustic Digital Current Meter) is designed for point velocity measurements in natural streams, rivers, creeks and open channels. Using the latest acoustic measuring principles and combined with a high end signal processor the instrument provides accurate and reliable data.

The instrument is equipped with a built-in pressure sensor that provides automatic depth readings for the determination of both individual vertical depths and prompting the user to set the correct sensor position.

The instrument easily attaches to different types of wading rods and features an automatic discharge computation based on the internationally recognized ISO and USGS standards.

It does not matter whether it is drizzle, sleet, hail or snow, the new OTT Pluvio² reliably and accurately measures both, the amount and the intensity of liquid, solid, and mixed precipitation.

It works according to the balance principle, taking account of external factors such as temperature and wind that could distort the results. Both, digital outputs (impulse/0.1 mm and frequency/status) and the serial interface, freely configurable as SDI-12 or RS-485, are available for transferring the data.

High-precision technology and robust design provide high accuracy and complete reliability.

Load cell and sensor electronics are hermetically sealed against damaging environmental influences. We have designed the carrier, bucket and protective housing parts to be particularly robust and we have ensured the use of high-quality materials.

The compact groundwater data logger OTT ecoLog 500 combines three features in one instrument: measurement, data storage and data transmission. The outstanding price-performance ratio is impressive - not only for qualities like longevity, precision and efficiency but also thanks to quick maintenance and comfortable handling.

Perfectly protected, all components fit into pipes from 2“. The state-of-the-art pressure probe is equipped with a rugged, ceramic-capacitive measuring cell, a precise temperature sensor and the data logger. The communication unit at the top end of the system holds batteries and data transfer components. The two units are connected with a Kevlar-reinforced cable with pressure compensation capillary.

The data telecommunication concept of GSM/GPRS-modem and antenna allows for great versatility (HTTP, FTP, SMS…). In addition to the measured data also alarm- and status messages can be transmitted.

A clearly structured operating program with online-help simplifies the configuration and data read-out on site. The infrared-interface of the communication unit is connected with the laptop via a special reading head; contact plugs which could corrode or deform don’t exist.

Thanks to the maintenance-friendly design, the battery, SIM-card and the desiccant capsule can be changed on site without any tools. A clever power concept makes the system stupendously energy-saving. Depending on the measurement- and transmission intervals, a lithium battery pack will last up to 10 years. This saves maintenance time and reduces data loss due to power cuts. Alkaline batteries might be used alternatively.

When the pressure in technical gas systems is to be kept constant, special safety valves are used, these blowing off gas at even the smallest pressure increases. To this end, the German manufacturer WITT has developed the new AV919 with a previously unavailable performance spectrum.

Even the smaller AV619 version is impressive. It blows off unwanted overpressure in a very low range from 5 to 500 mbar with the greatest reliability and consistency. As a comparison: Standard valves corresponding to the Pressure Equipment Directive 97/23/EEC applicable for this product group often only respond after an overpressure a hundred times greater. The new AV919 also masters these low setting pressures, while keeping a blow-off volume ten times greater at 967 m³/h under control. The opening pressure of the new development, still very compact despite being around 90 x 170 mm larger, is set precisely at the factory. The manufacturer can provide a TÜV (Technical Inspectorate Authority) test on request. This component weighing only around 1500 grams can be used with all technical gases in a wide temperature range from -40 to +300 °C.

Safety valves with an opening pressure below 0.5 bar are regarded as a technical challenge with the result that many systems work less accurately as the pressure decreases. Yet reliable functioning is not only crucial for economic viability but also for safety: Sensitive and expensive systems as well as their tanks and pipes for gas supply are relieved prior to reaching their operating limits, should the gas pressure rise unexpectedly. WITT is one of the few manufacturers with a complete programme comprising mixing, metering and control systems along with analysis and safety technology for almost all gas plants.

KM-Flow is the new WITT gas mixer with digital mass flow controllers (MFC) for packaging using a protective atmosphere in the food industry (Modified Atmosphere Packaging = MAP). Combined with permanent gas analysis, you receive online quality control for optimum packaging quality and reduce your gas consumption by up to 30%.

Depending on the model, the KM-Flow mixes two or three gases. The digital mass flow controllers (MFC) meter the selected gas mixture with highest precision and reliability.

A highly efficient packaging workflow can be realised with the innovative KM-Flow with MFC technology. In combination with an analysis instrument that continually measures the gas concentration in the packaging during the packing process, the KM-Flow can adjust the gas ratio and gas mixture flow rate to optimize the process. The result: maximization of the packaging quality along with a minimization of the gas consumption. Thus, the WITT gas mixing system helps to reduce costs and at the same time minimizes the uncontrolled escape of CO2 protecting employees.

The KM-Flow is easily operated by touch screen. Freely programmable gas mixtures can now be selected at the touch of a button or by barcode reader. Another advantage of the MFC technology: At all times the user has full overview of the exact mixing ratio, the flow rate of the mixed gas as well as the gas consumption. The digital data-bus also makes evaluation and documentation of the measuring data easier. You comfortably receive full transparency for your packaging process.

The KM-Flow offers highest flexibility. Naturally, the gas mixing system is suitable for all types of packaging machines. Thanks to the MFC technology, it is easy to configure and suit your individual needs.

WITT has a lot of experience with using mass flow controllers. For example, this technology has been used for supplying burners in the glass industry for many years. Of course, the KM-Flow gas mixing systems are certified according to ISO 22000 for food safety and the EG-Directive 1935/2004. Besides the food industry, the KM-Flow with MFCs can also be used in further applications.

R+W's standard program for its model family MK (miniature bellows coupling) is getting a new member, the model MKH. This new coupling features a half-shell clamp and is designed for torque moments from 0.1 to 10 Nm and shaft diameters of 1 to 28 mm.

Because it can be installed radially (made possible by the half-shell clamp), this coupling can be positioned exactly. No complex axial shifting of components is necessary. This coupling's lack of backlash makes it suitable even for highly dy-namic applications and confined installation spaces..
Like every R+W metal bellows coupling, the MKH is stable over its entire service life when correctly assembled and used.

With the introduction of this new model, R+W is now able to offer economical, optimally-dimensioned, metal bellows couplings with the advantageous half-shell clamp that cover a torque range from 0.1 Nm to 1500 Nm.

The use of ST series safety couplings substantially reduces downtime in the aftermath of a machine crash, thereby increasing the availability and production performance of the equipment.

Designed for use in shredders, crushers, rolling mills, steel mills, conveyor equipment and extruders, the compact, simple, yet robust design of the coupling makes maintenance-free operation possible throughout its entire service life. In comparison to other couplings currently available on the market, an ST coupling possesses as little as 25% of the mass.

The fact that disengagement torque can be very easily adjusted is another advantage. This can be changed simply, without any aids (such as a datasheet for example), by virtue of the force range, marked on the indi-vidual actuation segments.

The company R+W, headquartered in Klingenberg, Germany, presents the new model MKS - the most recent member in its product line of miniature bellows couplings (MK). This coupling's attachment via a special conical hub makes it well suited for very high speeds up to 150 000 RPM. The extremely high speed rating is made possible by pre-centering, by the clamping hub's very smooth running accuracy, by highly precise fabrication of the metal bellows and by the backlash-free principle of R+W couplings.

Standard balance quality ratings of 6.3 and 2.5 are possible. The coupling's symmetric structure also permits Q 1 dynamic balancing in special cases. The model MKS is designed for torque loads of 0.1 to 10 Nm and shaft diameters from 1 to 28 mm.

R+W, the coupling's manufacturer, has even made disassembly of this new mod-el's conical bushing easy by virtue of an extraction thread as a standard feature.

The coupling manufacturer R+W Antriebselemente GmbH in Klingenberg, Ger-many presents a world premier in the field of safety couplings. This innovation combines intelligent lightweight design with high-tech materials and the latest production techniques.

The new SL coupling series is fabricated from high-tech materials in combination with uniquely plated surfaces. This permits weight to be reduced by up to 60 % in comparison to a standard series coupling. A coupling rated for a torque limit of up to 160 Nm weighs only 370 gram and has a 0.8 * 10-3 kgm2 moment of inertia. This ratio of torque rating to dimensions and weight is currently unique.

There are currently no other comparable safety couplings on the market which can guaran-tee this power density. This series of couplings includes 4 sizes. The series begins with safe torque limit ratings of 5 Nm and extends to far beyond 700 Nm.

ZMD AG (ZMDI), a global supplier of energy-efficient analog and mixed-signal solutions for automotive, industrial, and medical applications, today introduced four smart sensor signal conditioner ICs. ZMDI designed the ZSSC3131, ZSSC3135, ZSSC3136 and ZSSC3138 for the signal conditioning of resistive bridge sensing elements, like silicon or ceramic-based piezo-resistive transducers or thin-/thick-film or gauge-type sensor elements. The devices are ideal for automotive and industrial pressure sensing applications such as HVAC, cooling, pneumatic brakes and other hydraulic systems.

“Sensor system designers can select among four pin-compatible products to obtain the best fit in terms of sensor type, system safety and module cost requirements,” states Steffen Huettner, automotive SSC Product Marketing Manager at ZMDI. “The different feature sets allow for applications ranging from under and over pressure switches for hydraulic and pneumatic systems all the way to failsafe, SIL compliant switches and high accuracy pressure monitoring systems for HVAC and pneumatic brake applications”.

Diagnostics functions range from a basic sensor connectivity check with the ZSSC3135 and ZSSC3138 to a complete set of SIL compliant sensor diagnostics with the ZSSC3136. The ZSSC3135 and ZSSC3136 provide an external sensor temperature measurement for an on-chip compensation of sensor temperature effects and increased system accuracy.

When used in ceramic sensor based systems, the ZSSC3138 with its on-chip offset compensation capability eliminates the need for sensor laser trimming in production and allows sensor system suppliers to reduce manufacturing costs while increasing long-term offset and temperature stability of the sensor system.

The devices are available in a SSOP-14 package. Pin-compatibility allows system designers to develop several designs in parallel enabling shorter time to market and flexibility.

An automatic end-of-line procedure, communicating via digital one-wire-interface (I2CTM / ZACwireTM), compensates sensor offset, sensitivity, temperature drift and non-linearity within a single calibration pass sequence.

All devices have an analog ratiometric voltage output and they operate with supply voltages between 4.5V to 5.5V. They are available for temperature ranges from -40°C to +125°C and -40°C to +150°C.

Input signal measurement accuracies are within +/- 0.25% full-scale operational range at -25 to +85°C and +/- 0.50% full-scale operational range at -40 to +125°C. All devices have integrated high-voltage protection up to 33V, robust ESD and EMI stability, reverse polarity and short circuit protection and meet automotive AEC-Q100 standard.

Packaged parts in volumes of 1,000 devices are priced at € 2,95 / USD 4,28 (ZSSC3131), at € 3,03 / USD 4,39 (ZSSC3135), at € 3,19 / USD 4,62 (ZSSC3136), and at € 3,25 / USD 4,71 (ZSSC3138).

ZMD AG, a global supplier of analog and mixed-signal solutions for automotive, industrial, and medical applications, is introducing its first step-up converter with integrated 35 V power switch for high brightness LEDs. It is optimal for driving multiple white LEDs connected in series from a low voltage supply. The ZLED7015 can also drive devices that require a constant voltage and the wide input voltage range of 6V to 30V supports applications with input voltage from multi-cell batteries or regulated 12V and 24V power rails. A low voltage feedback mechanism helps maximize the operating efficiency and the device’s soft-start function and open circuit detection protects the application circuit and extends the LED life.

The low voltage, constant current operation makes the ZLED7015 an ideal choice for safety extra-low voltage (SELV) applications with less than 24V in damp environments. The device is also an ideal driver for multifaceted reflector (MR16) lamps, frequently found in residential and retail lighting applications. Other key application areas include low voltage retrofit lighting, replacement tubes, LED backlighting, aftermarket automotive lighting products, low voltage general purpose industrial and consumer applications, as well as signage, outdoor, architectural and building lighting.

„The step up topology of the ZLED7015 enables applications using multiple high brightness LEDs strings while being driven from a low voltage source“, stated Andy Smith, Product Manager at ZMDI. “This is particularly attractive for designers of low voltage high brightness lighting products. Other benefits include simplified manufacturing, lower cost, higher efficiency and greater reliability.“

The ZLED7015 is ideal for customers using 6-30V supply to drive multiple high brightness LEDs. The device includes an integrated power switch to minimize system cost and reduce component count for size optimized applications. The output current is programmable via external components and features PWM, Linear and DC voltage dimming.

The ZLED7015 operates with a switching frequency up to 1MHz allowing the use of smaller, less expensive external components. A low 0.3V feedback voltage minimizes power loss in the current setting resistor for better efficiency. With an adjustable over voltage protection, the chip and the system operates safely even if the load is not connected or the output is short circuited.

A built-in soft start circuit significantly reduces the inrush current during start-up and extends the LEDs lifetime. Further features include an under voltage protection as well as an over temperature protection.

The operating temperature range of the ZLED7015 is -40°C to 85°C. Samples and a complete evaluation kit are available now. The ZLED7015 comes in a MSOP-10 package and is RoHS compliant. For 5,000 pieces, the ZLED7015 is priced at €0.35/$0.46.

OSIL have supplied a unique water sampling system of innovative design for use in the offshore oil industry.

OSIL were approached by a well known oil major to assist with a unique water sampling requirement off the West African coast. The system was required to retrieve multiple samples, with space for a CTD probe (or similar instrument to collect background data), and had to be fitted to and operated by ROV under difficult conditions. The samples were to be collected at fixed depth, and had to be collected in conjunction with other ROV samples.

This prevented the use of traditional wire water sample collection methods, due to the risk of entanglements.

OSIL used the industry standard Niskin bottle due to its robustness, and designed a sampling system to secure 6 primed 5L Niskin bottles, with space for an AML Oceanographic CTD Plus V2 in the centre of a stainless steel frame, which could then be mounted to the ROV.

OSIL specialise in providing cutting edge solutions for marine and environmental problems, and the ROV sampling system is a further example of how they cater to their customers needs and ensure that they provide each application with the most appropriate instrumentation at the highest standard possible.

The system is being used off the coast of Nigeria in the exploration for offshore oil.

OSIL are delighted to offer a new upgrade to their MiniBAT underwater towbody system.

OSIL have fitted a custom-built splashproof housing for the electronic controls. This will now provide a fully wet-mateable system, with all controls in a single, rugged, corrosion proof suitcase. OSIL are also able to provide the same housing for any ancillary systems the MiniBAT have, such as underwater video, or water quality sensors.

The OSIL MiniBAT is an extremely lightweight, remotely controlled towed instrumentation platform designed for use with a wide variety of data collection instruments. It provides an extremely flexible profiling system for use in estuaries, lakes, rivers, and coastal areas, and is easily deployed by 1 person from virtually any size of vessel.

The MiniBAT is software controlled and can be set to undulate over a desired depth range, maintain a constant depth, and can even be programmed to follow the seabed with the MiniBAT automatically altering its depth. With an operational depth of 60 m and profiling speed of up to 10 knots, the MiniBAT enables users to collect large spatial datasets quickly and efficiently saving both time and money. The software allows continuous measurement and real time display of the data, transmitted with water quality data from other sensors.

The MiniBAT offers the ultimate in rapid inshore data collection bodies.

Internationally recognised sunglasses brand, Polaroid, have chosen to carry out product testing using OSIL’s Atlantic Seawater Conductivity Standard.

The tests are designed to simulate the ageing of the product, and include various products and chemicals encountered in the usual life of the sunglasses, such as sun lotion and hair products, as well as the stresses imposed on the products when being opened and put on.

The sunglasses are subjected to the equivalent of about 2 years worth of use, and are exposed to OSIL’s Atlantic Seawater to replicate the familiar scenario of dropping sunglasses in the sea, swimming in the sea, or sailing.

This filtered natural ocean water (S = 35) may be used in a wide range of applications including field probe calibration/checks, chemical analysis, particulate studies, corrosion testing and any other applications which require open-ocean seawater.

The label value is quoted in salinity and in specific conductance (mS/cm) with a confidence of ± 0.2%, and is available in two pack sizes, 4 x 5 litres or 10 x 500 ml bottles.

The Atlantic Seawater “was chosen for its consistency, offering real life replicability at an affordable price”.

Dr Richard Williams, Managing Director of OSIL, commented “yet again this is another fascinating use for our seawater products, which have included thalassotherapy treatment for racehorses, psoriasis treatments, and product testing for marine paints”.

OSIL are pleased to offer a complete Scour Monitoring and Data Review Package for wind farms and other similar structures.

Scour is a significant concern for owners and operators of offshore structures, as erosion of the sediment in the vicinity of a structure can lead to a lowering of the seabed directly surrounding the structure, undercutting foundations and decreasing the stability and lifespan of the structure. Offshore wind farms are now being proposed for, or built in, increasingly hostile hydrodynamic environments, and many candidate sites are located on beds of mobile sediments. In these cases, the interaction of the sediments with the turbine support structure, and the effects of flow- and wave-induced scour of the sediments must be carefully observed.

The package available from OSIL comprises an acoustic Scour Monitor, which is then coupled to the clients own data handling system, or to the OSIL Falcon or Falconet Data to Web Logger – which will then permit instant access to a web-based data display, eliminating the need to re-visit the unit to manually download data, or to perform ship-based surveys (which are restricted in the areas they are able to survey).

The Scour Monitor is mounted directly onto the turbine pile, and comprises four downward looking narrow acoustic beams (fanned out on a single axial plane) which provide a profile of the seabed close to the base of the pile.

Changes in the seabed surrounding the structure, or scour, can therefore be measured and observed in real-time, even during storm periods, thus providing invaluable information for modelers, operators, civil engineers, and all interested parties, of these crucial changes as they occur.

Terahertz ATR spectroscopy can be used for far-infrared analysis of liquid samples, and also to analyze powders without sample preparation. Hamamatsu expects for its new instrument to be used in a wide variety of applications, including pharmaceutical analysis, evaluation of hydrates, and non-destructive spectroscopic inspection of liquids, powders, and solids. Sales of the instrument to research institutes and R&D departments will begin in April 2012.

The technology in Hamamatsu’s new instrument, which was developed with the Innovation Promotion Program of the New Energy and Industrial Technology Development Organization (NEDO) of Japan, will be exhibited at the JAIMA EXPO 2011, one of Japan’s largest trade shows for analytical instrumentation, from September 7 to 9 (Makuhari Messe, Chiba).

Hamamatsu Photonics K.K. has developed three new types of thermopiles for power-saving and security applications, including gas analysis, temperature measurement, and human body detection. The three types of thermopiles consist of area sensors (T11264 series), linear sensors (T11263 series), and dual sensors (T11722 series). Each features CMOS circuitry, and was developed with Hamamatsu’s MEMS technology. Samples will be available to manufacturers of home electronics, industrial equipment, and security devices from October 1, 2011. Product shipments are scheduled to begin from April 2012.

From September 28 to 30, Hamamatsu’s new thermopiles will be exhibited at the InterOpto 2011 international optoelectronics show at the Pacifico Yokohama exhibition center (Yokohama, Japan).

Nikon Corporation (Makoto Kimura, President, Chiyoda-ku, Tokyo) released the latest ArF scanner, "NSR-S320F," with the concept of achieving high productivity and high accuracy.

NSR-S320F ensures early realization of stable operation and high productivity in the customers' fields with its platform proven in Nikon's immersion scanner.

VLSI chips, the backbone of the IT revolution, continue to shrink and get denser. The semiconductor industry is transitioning to development and high volume manufacturing of a 20 nm generation process device. The most critical layer is exposed with an ArF immersion scanner, but other critical layers as well as non-critical layers are normally exposed by an ArF scanner or KrF scanner.

NSR-S320F is the scanner that responds to the need for such a cutting-edge device. By employing Streamlign Platform, which has been proven in our immersion scanner, early realization of stable operation and high productivity is ensured.

Throughput is increased by an approximate factor of two compared to Nikon's existing scanners, and CoO (Cost of Ownership) has been significantly reduced. The level of overlay accuracy achieved is comparable to ArF immersion scanners, and it also has the potential for further expandability in the future.

Renewable energy systems, including solar, wind, wave and tidal power, are ideal applications for composite plain bearings.

In solar energy systems, for example, plain bearings are particularly suitable to the operating conditions, which often involve slow swiveling movements with high loads. In addition, plain bearings are also suitable for operation in media such as water (hydro power) and for dry running applications.

The Schaeffler Group has a rapidly expanding range of plain bearings for renewable energy systems. In addition to its Metal-Polymer Composite Bearings range, Schaeffler also recently launched its ELGOTEX plain bearings.

Metal-polymer composite plain bearings

Schaeffler’s metal-polymer composite bearings are particularly effective in oscillating applications, where the bearings achieve a higher basic rating life than conventional bearings. These products are available as bushes, flanged bushes and thrust washers and are ideal for applications where there are very small radial or axial design envelopes.

The metal-polymer composite material provides low-wear sliding characteristics, as well as a high load carrying capacities and high thermal conductivity. Static load carrying capacities of up to 250 N/mm2 can be achieved. Composite materials can also be used in water or other media due to its high moisture resistance.

Metal-polymer composite bearings are a cost-effective alternative for applications with minimum available space and a comparatively high sliding speed. The plain bearings are available as bushes and flanged bushes, as well as thrust washers and strips. The material can also be easily formed to specific customer requirements for rotary, linear and oscillating movements. All Schaeffler’s metal-polymer bearings are lead-free.

Three different materials are available in the range: a selection of bearings with maintenance-free and low-maintenance materials E40 and E50. The two material structures are similar: a porous bronze-sintered structure is applied to a steel or bronze backing and impregnated with a special plastic compound. The solid lubricant produces a lubricant film between the sliding surfaces, which provides low-noise operation with a constant low friction coefficient throughout the entire service life of the bearing.

E40 bearings are generally maintenance-free, i.e. lubrication is not required over the entire operating life. PTFE and different chemically inert additives are used as the lubricant. E40 is recommended for rotary and oscillating motion applications, as well as for short stroke linear movements.

Bearings with E50 are low maintenance, although initial grease lubrication is required at start-up. The sliding layer comprises mainly polyoxymethylene (POM), a high-molecular thermoplastic characterised by its low friction properties, as well as chemical and thermal stability. E50 is a low wear material that has good damping properties and long relubrication intervals. The material is ideal for rotary and oscillating movements and is also recommended for long stroke linear motion applications.

Bearings with the E60 sliding layer are maintenance-free foil bearings. These have a lattice structure in which a sliding layer of PTFE and other additives is rolled and sintered. The structure functions both as a backing and a sliding layer. The PTFE sliding layer is on both sides of the foil so that the sliding motion can take place on the inside and outside of the bushes. A further advantage is that E60 can be easily moulded.

ELGOTEX plain bearings

Schaeffler’s ELGOTEX® range of plain bushes provides a variety of technical advantages that stem from the product’s unique, entwined double-layer design.

Each bush comprises two layers of wound (twisted) material. The inner, sliding layer is made from synthetic fibres and PTFE fibres in epoxy resin, whilst the outer layer comprises continuous glass fibres (filaments) in epoxy resin. This combined, double wound material is stabilised by applying a specific winding angle to the glass fibres, which significantly increases the strength of the bush.

The result is a host of technical advantages, including extreme robustness, compactness and low wear (due to consistent friction levels). In addition, ELGOTEX® plain bushes are lighter than their bronze equivalents.

The bushes are easy to mount and require no further axial location. Due to their dry-running characteristics, the bushes are also environmentally friendly. The bushes are maintenance-free for life, resulting in reduced maintenance costs for the end user.

ELGOTEX® has already proved itself in many customer applications, including those in which high radial loads or high static loads are present. The new bushes are also insensitive to shock loads and edge pressures.

The product is available with integrated seals and is resistant to corrosive media. The bushes also perform well in applications where swivel or axial movement is required. Good vibration damping properties is a further benefit of ELGOTEX®.

INA plain bushes with ELGOTEX® are available with bore diameters from 20-200mm, outside diameters from 24-220mm, and widths of 15-250mm. Custom versions with outside diameters up to 1,200mm are also possible.

A new, groundbreaking sensor has been developed that enables the online condition monitoring of grease in rolling bearings. The sensor is ideal for monitoring critical plant and machinery located in difficult-to-access areas, such as wind turbines and automated assembly lines.

Developed by The Schaeffler Group in conjunction with Freudenberg Dichtungs- und Schwingungstechnik GmbH & Co. KG and lubricants specialist Klüber Lubrication, the new grease sensor incorporates a unique electronic evaluation system, which enables the condition of the grease to be monitored whilst the bearings are operating. The sensor is positioned directly in the rolling bearing immersed in the grease.

This is a significant breakthrough, as the schedule for replacing rolling bearing grease can now be planned precisely into maintenance schedules. Any changes in the condition of the grease are detected early, long before any damage can be caused to the bearings.

Grease operating life is key to maintenance

In preventive maintenance regimes, the operating life of the grease is critical, particularly if the life of the grease is less than the expected life of the bearing. In this case, the bearings would normally be relubricated halfway through the grease operating life. The disadvantage here is that the grease is replaced without knowing anything about the actual condition of the grease. For example, it may have been possible to continue using the grease for a longer time period without affecting the performance of the bearing. Conversely, perhaps damage has already occurred to the bearing due to ingress of water or high temperatures and so the grease should have been replaced earlier.

Up to now, users could only gather information about the condition of the grease inside a bearing by taking a sample and then conducting costly, time-consuming analyses of that sample in a laboratory. However, the new grease sensor enables grease to be replaced according to the actual operating requirements of the bearing and not according to any pre-defined time periods. This is referred to as ‘demand-based’ rather than ‘time-based’ relubrication. The result is a reduction in the cost of lubricants, replacement parts and maintenance, whilst also benefiting the environment in terms of the volume of lubricant used. In addition, operational downtime of plant and machinery will be reduced, whilst process efficiencies and machine utilisation will also improve.

How does it work?

The grease sensor, which has a diameter of just 5mm and a length of 40mm, is able to detect four parameters of the grease: water content, cloudiness (opacity), wear (thermal or mechanical), and temperature. From these parameters, the sensor’s electronic evaluation system utilises complex software algorithms to generate an analogue signal (4-20mA), which then displays the condition of the grease. By setting alarm thresholds (limit values), digital signal outputs can also be generated, indicating whether the grease quality is ‘poor’ or ‘good’. The user can decide at which point in the condition of the grease (from 100% for as-new, to a theoretical 0% for an unusable grease) relubrication or grease replacement should be carried out.

Process development with The Fraunhofer Institute

The sensor operates by using the optical, near-infrared reflection principle. This method – developed in conjunction with the Fraunhofer Institut for Electronic Nano Systems (ENAS) in Germany – is based on an infrared process used by laboratories to measure the quality of grease, but has been adapted for online measurements in rolling bearings.

The know-how involved in developing the grease sensor is not only in the set up of the sensor, but also in how measurements are evaluated.

In terms of evaluating measurements, the method involves the rotationally symmetrical irradiation of the grease at an angle of 45 degrees using certain wavelengths within the infrared spectrum by the sensor. The sensor head is embedded directly in the lubricant during this procedure. The reflected light is measured perpendicular to the grease, which enables any shadow effects or surface anomalies to be completely excluded. The reflected light is then evaluated in terms of the quality of the grease.

In terms of sensor set up, the optimum measurement point will vary depending on the application. Experienced application engineers at Schaeffler will provide advice and guidance to customers and will specify where the sensor should be positioned for each specific application.

Cables are used to provide power to the sensor and to transmit signals from the sensor to the electronic evaluation system. However, if required, a wireless solution can be provided.

Schaeffler, Freudenberg and Klüber have validated the measurement method for around 95 per cent of greases currently available on the market. Online monitoring of the condition of the grease enables users to draw conclusions and to react quickly to any changes that may suddenly occur. It also enables the optimisation of bearing design and position.
