Variohm EuroSensor has launched a new range of heavy duty, sealed linear position sensors for extreme operational environments. The new LWX series from Novotechnik builds upon the successful LWG rod actuated potentiometric design with additional sealing to IP67 protection rating and features a new patented pressure equalisation technology that prevents 'pump effect' pressure build up.

Electro-Sensors, Inc. announces the ST420, a loop-powered, stainless steel analog shaft tachometer. The ST420 requires no user calibration, providing a dependable shaft speed monitoring solution right out of the box. The rugged, compact ST420—only 18mm in diameter—reliably detects magnetic pulses from a rotating shaft-mounted pulser disc or wrap. Then, the ST420 uses quartz crystal-based digital processing to convert pulses to a smooth, continuous 4-20mA analog signal directly proportional to the pulse frequency. The result is a plug-and-play solution that allows users to accurately and simply monitor rotating shaft speed in industrial applications.

By incorporating the second generation “in-cell” amplifier (ICA) from LCM Systems, engineers can convert a strain gauge input to a voltage or a current output. This high performance, sub-miniature amplifier can be used for internal amplification of strain gauge based load cells, pressure transducers or torque transducers.

Analytical Technology Inc. announces that it has added 24VDC powered and digital options of the Profibus DP (Decentralised Peripherals) standard across its full range of monitors, including its extensive chlorine range, in response to customer demand. The addition of Profibus DP standard to Analytical Technology’s monitors enables water and wastewater treatment plants to optimise maintenance and achieve a high level of confidence in chlorine measurements.

Deeter Electronics, announces the introduction of a Wireless Router to increase the range and reliability of their recently launched Deeter Wireless Sensor System for industrial measurement and control.

PI Ceramic -- a leading manufacturer of piezo ceramic materials, piezo components and custom engineered piezo products -- has released a new website.

VPInstruments has changed the design of her proprietary flow sensor. Due to this new flow sensor design and a review of our calibration protocol, we offer now our insertion flow meters with one flow range; with good accuracy over the entire flow range. This flow range combines the accuracy in the low flow ranges of the old version with flow range up to 80 mn/sec, with the flow range extension of our model up to 150 mn/sec. The new flow range, 0.5..150 mn /sec, combines all benefits. With only one model you are now equipped for all your compressed air and gas flow measurements. Selecting the right flow meter has never been so easy!

Cypress Semiconductor Corp. announced that Fujitsu Limited has selected Cypress's TrueTouch(tm) solution to implement the touchscreen in the world's first separable handset from NTT DOCOMO, the docomo PRIME series F-04B mobile phone. The new phone leverages Cypress's CY8CTMG200 controller to power the robust multitouch interface with a slim 9.8-mm form-factor that can operate separately from the keyboard. By detaching the phone's keyboard from the display, users can easily send e-mails, watch TV broadcasts or search address books using the touchscreen interface while talking on the baseband.

Gems Sensors & Controls, introduces the RFO type of the RotorFlow Series of fluid flow sensors. RFO stands for “RotorFlow Output”, and is designed for flow rate monitoring or metering applications. RotorFlow RFO type sensors provide a pulsed DC voltage output that is proportional to the rate of flow. The 4.5 to 24VDC pulsed output is easily integrated into most digital logic units. What makes RotorFlow sensors unique is the highly visible paddlewheel that provides verification at a glance to confirm that fluids are moving. Typical applications for RotorFlow RFO type sensors include water purification, dispensing systems, chemical metering, laser and welders, semiconductor processing, water injection systems, and chillers and heat exchangers.

Sensor Developments Inc's rolling resistance load cells are able to precisely measure the low drag forces while supporting the very high overturning moments and radial loads that occur during testing.
