MEMS-Based SS Pressure Sensor Ideal for High Purity Applications


Mt. Olive, NJ - American Sensor Technologies offers the AST4900, a competitively priced, high-quality pressure sensor for use in the measurement of gases and liquids in high purity applications. Utilizing Krystal Bond™ Technology, these stainless steel sensors are free of oil-fill, welds and internal O-rings, all of which eliminate the risk of system contamination in extreme conditions. The AST4900 media isolated pressure sensor also holds a CE EN61326 Certification and UL/cUL508 Approval.The AST4900 is available in two standard fittings: 1/4" NPT Male and 1/4" VCR Male. Each sensing element is machined from 316L stainless steel and electropolished to remove any contaminates. “This process polishes the metal surface by removing a microscopic amount of material from the work piece. Moreover, electropolishing is a process which uses an acidic viscous medium for the transportation of ions to allow surface undulations to form a more planar surface finish.” This one-piece design can also be manufactured with Inconel718, a nickel alloy that holds a wide range of chemical compatibility ...

New SCHMIDT® Flow-Sensor SS 20.500 for Dusty Environments


SCHMIDT Technology presents for the first time the new flow sensor SS 20.500 for application in chemical processes on the international exhibition ACHEMA in Frankfurt. The measurement of flow velocity in dusty environments results in particular sensor requirements. Dirt tolerant design and easy cleaning are of high importance to guarantee measuring accuracy and reproducibility. Unwanted accumulation of dust and contamination on the sensor tip can be avoided by an optimized aerodynamic flow. Therefore, the sensor dumb-bell tip was developed and the patented system has been proved in many applications ...

 New Retractable pH Sensor for Tough Industrial Applications


Warminster, PA, April 02, 2009 - ABB has announced the release of the Endura TBX587 Retractable pH sensor. Responding to customer requests, the Endura TBX587 targets 1-inch NPT process connections found in sample lines in refineries, chemical plants, and other industrial applications. The Endura TBX587 incorporates many innovative design elements into one convenient pH measurement system. The temperature compensation element has been moved to the tip of the sensor to provide response times up to 6x faster then conventional gel-filled pH sensors. An optional IP68 Vario Pin style cable connector simplifies sensor replacement without complicated wiring or terminal strips. The mechanical design of the Endura TBX587 includes a large “T” style handle to aid in insertion and retraction into pressurized process pipelines ...

Absolute Encoders Go Wireless


BEI Industrial Encoders introduces the SwiftComm Wireless Interface for SSI absolute encoders. No need to incur the expense and maintenance of long cable runs - go wireless! Using SSI communications protocol at the transmitter and receiver end, users can connect the wireless receiver directly into the SSI port in the controller, just like a conventional wired system. The interface works with any SSI position device; single or multi-turn encoders, linear scales, magnetostrictive devices or any other SSI sensor. A robust and secure wireless interface, SwiftComm has the built-in reliability needed for real-time industrial control. Able to interface with any SSI absolute or incremental sensor, SwiftComm allows critical position and speed feedback data to be seamlessly sent to control systems without expensive cabling. The SwiftComm system includes the transmitter-receiver pair, which communicates using a point-to-point frequency-hopping 2.4 GHz RF protocol. SwiftComm is ideal for a wide variety of industrial applications where cable runs are expensive to install and maintain ...

Encoder Devices for Various Angle Sensors


The new encoder device iC-TW4 is a highly integrated sine-to-digital converter for the evaluation of magnetic or optical linear and angle sensors. Two setup pins deter-mine the chip function, the signal gain and the rate of interpolation within a range of x2 to x64; the sine/cosine sensor signal can be divided up into 256 angle steps and output as an encoder quadrature signal via the RS422 drivers. iC-TW4 combines all the necessary encoder functions in a tiny QFN package measuring just 4 x 4 mm; signal gain, conditioning, A/D conversion and serial line drivers are integrated in the device. Apart from the angle sensor a measurement system does thus not require any further active external circuit components for operation. The chip is configured using two configuration pins. A static network of resistors consisting of two resistors apiece defines the factor of interpolation, the converter hysteresis and the input voltage range, making a digital interface or an external EEPROM for the storage of the configuration superfluous ...

Extended Testing of Landing Flap Gearbox with CoMo Torque Evaluation System


Aircraft flaps take the form of extendable extensions on the trailing edges of the wings. During the approach they allow the lift necessary to make it possible to reduce flying speed for landing. Liebherr-Aerospace also manufactures flight control, actuation, hydraulic and a variety of other systems for use in business jets, feeder aircraft, wide-bodied civil aircraft, helicopters and military aircraft. Special gearboxes with differential output drives are used in flap actuation components. To enable them to meet stringent service life and wear requirements these gearboxes have to be tested on a special stand, with drive and load machines applying specific load profiles to simulate realistic flap movements. To enable reliability assessment the input torque is measured as a function of speed with a Kistler sensor Type 4503A. Incorporation of the speed measuring system into the sensor allows a compact, clearly arranged configuration of the drive train in the test bay ...
