Contelec debuts rotary encoder

Contelec has launched its Vert-X 05E ultra-compact rotary encoder with physical architecture designed for extremely tight spaces. Encapsulated in a high-grade, temperature-resistant epoxy resin, it is impervious to contamination. With IP68 protection rate and an operating temperature range of ” 40 à‚°C to + 125 à‚°C, it is intended to stand up to the harshest environments.

Just 5 mm high, the extremely slim angle sensor catches the eye with its unusually compact size and arrangement of its measurement system only 6 mm from the edge, according to Contelec. This allows the Vert-X 05E to be used in applications with a rotation centre close to a wall and enables angle measurement in hitherto inconceivable places.

Selection of the direction of rotation (clockwise/counter-clockwise) is easier than ever, according to the machine’s maker. The Vert-X 05E can simply be installed flipped through 180 degrees, completely eliminating the need to program the angle sensor.

ExxonMobil extends its multi-purpose Mobil SHC 600 series of oils

ExxonMobil Lubricants and Petroleum Specialties Company (L&S) has launched its next generation of Mobil SHC 600 Series lubricants. These high-performance, synthetic gear circulating and bearing oils are the latest addition to the Mobil SHC brand of high-performance synthetic lubricants designed to increase productivity, reduce costs and lower energy consumption.

In extensive laboratory and in-service testing, next-generation Mobil SHC 600 Series lubricants exhibited energy savings of up to 3.6 per cent compared with conventional oils, said their maker. In addition, featuring the latest Mobil SHC technology with advanced synthetic base fluids and a proprietary additive system, the enhanced Mobil SHC 600 Series oils can deliver a service life up to six times longer than competitive mineral-oil based gear and bearing lubricants, according to their maker.

The enhanced Mobil SHC 600 Series lubricants are designed to deliver other benefits including outstanding low temperature fluidity to enable start-up and operation at low temperatures, and excellent resistance to rusting and corrosion. Also, the multi-purpose potential of Mobil SHC 600 Series oils can enable companies to reduce their overall lubricant inventory, delivering additional cost-savings and storage benefits.

“The next generation of Mobil SHC 600 Series oils have been developed to push the boundaries of lubricant performance and outstanding equipment protection while delivering sustainability related benefits such as reduced energy consumption and increased oil drain intervals,” said Michael J. Hawkins, Mobil SHC global brand manager, L&S.

The Mobil SHC 600 Series oils are recommended for use in 1800 applications by more than 500 major equipment builders, including Siemens, for use in Flender gearboxes, according to ExxonMobil Lubricants and Petroleum Specialties Company. In addition, the enhanced series is approved by leading gearbox manufacturer SEW-Eurodrive for factory-fill and service-fill worldwide, said the firm.

They are also fully compatible with system components and materials used in equipment normally lubricated with mineral oils, which helps maintenance professionals minimise equipment issues during the conversion process.

GE introduces portable scanner

The CRx25P computed radiography (CR) imaging solution from the Inspection Technologies business of GE Energy’s Measurement & Control Solutions is designed to combine high scanning resolution and throughput with compact design and light weight.

Martin Sauerschnig, product manager at GE, said: “Weighing just 21 kg, the CRx25P represents the latest generation of portable scanners. It features an upgraded plate transport system, which optimises plate handling, and it accepts flexible phosphor imaging plates up to 35 cm wide and of virtually any length, with one plate being fed into the unit while the other plate is being scanned.”

The CRx25P can be operated at 50 micron or 100 micron, suitable for corrosion/erosion inspection. It can also be operated at scan resolutions of 17 micron and 25 micron, making it qualified for weld inspections in compliance with international standards. A battery-powered version enables autonomous operation in special environments.

Sensonics extends DN803X range

Machine Protection and Condition monitoring specialists Sensonics has enhanced its range of DN803X series shaft vibration and thrust position transmitters following approval for intrinsically safe applications.

The DN8031 (vibration) and DN8033 (thrust position) proximity probe systems are now suitable for Ex ia IIC T4 applications when used with Sensonics ATEX approved range of AECP proximity probes and AEXC extension cables.

The 4-20mA loop powered modules provide easy integration with either the local machine PLC or a plant wide DCS since they are powered through the safety barrier measurement loop.

All signal processing is carried out within the unit, providing an output current proportional to either peak-to-peak shaft vibration or relative position to the probe face. The module permits the adjustment of both gain and offset for ease of calibration to suit the application.

Kistler presents Type 4550A KiTorq

Kistler, a worldwide supplier of precision sensors, systems and instrumentation for the dynamic measurement of pressure, force, torque and acceleration, has introduced the Type 4550A KiTorq rotor torque flange measuring unit.

Featuring an accuracy class of 0.05, the bearing and slip-ring free design of the Kistler Type 4550A KiTorq system consists of a combination of both the Type 455x KiTorq rotary torque measuring unit and the Type 454x KiTorq stator torque evaluation unit.

Both rotors and stators within the KiTorq system with the same speed option may be used in any combination with one another. The rotor may also be purchased individually ” or as part of a fully calibrated torque measurement chain ” together with a KiTorq stator. The stator automatically detects a change in the rotor and then automatically sets required measurement parameters.

All KiTorq rotors capture torque using strain gauges (DMS), with their generated signal amplified and then processed at approximately 35 kSample. This high-speed scanning rate means that widely dynamic torque parameters can be measured to high degrees of accuracy and repeatability.

In addition, various calibration options are available for the configurable output signals of the KiTorq system, said the unit’s manufacturer. All calibrations are conducted within a high-precision calibration system that is fully traceable to recognised standards.
