Miniature Accelerometer Weighs 0.20 Grams

 

October 5, 2007, Depew, NY, USA PCB Piezotronics (PCB) has introduced Model 357A19, a very miniature charge output accelerometer, designed for performing shock and vibration studies in space-restricted locations and on small, lightweight structures. The unit occupies a 0.11 x 0.16 x 0.27 inch (2.8 x 4.1 x 6.9 mm) envelope, and weighs a mere 0.007 ounces (0.20 grams), for minimal mass loading of a test article. The unit connects to laboratory-style charge amplifiers or in-line charge converters, which condition an output signal for recording or analysis.

 

Model 357A19 features an operating temperature range of -100 to +350 F (-73 to +177 C) and is ideally suited for thermal cycling and vibration stress screening of circuit boards, disk drive mechanisms, mobile phones, PDAs, and other electronic devices. Other applications include NVH studies on automotive parts and modal analysis of small structures and satellite components ...

Wet/Wet Differential Pressure Sensor Ideal for Monitoring Cleanliness of Filtration Systems

 

Mount Olive, NJ, American Sensor Technologies offers a wet/wet differential pressure sensor ideal for monitoring the cleanliness of filters in either liquid or gas applications.  When installed within a water filtration system, the Model 5000 Wet/Wet Differential Pressure Sensor can detect the difference between the upstream pressure, that drives the water through the filter, and the downstream pressure, that leads the filtered water through the system, to notify the system when the filter is clogged.

 

For example, in a 100 PSI pump using a filter to purify water for drinking, if the pressure in the downstream side of the system drops to 80 PSI, the filter should be changed.  With a 24VDC supply powering the Model 5000 wet/wet different pressure sensor and a selected 4-20mA output signal, the sensor can be calibrated with a 100 PSI line pressure and a 20 PSI differential pressure ...

Smart Laser Level Transmitter Features Explosion-Proof Ratings and HART Protocol

 

Houston, TX (October 3, 2007) - K-TEK, announced at ISA Expo 2007 the SureShot 140XP Explosion-Proof, Smart Laser Level Transmitter. The device is designed for precise level, distance, and position measurement of dry bulk solids, opaque liquids, and slurries in challenging environments. High performance optics include a measurement laser and an aiming laser to assist with alignment. The device is capable of measuring over extended distances, up to 240 ft (75 m) with narrow beam. No beam divergence means no false echoes so accurate targeting is easy, even in silos or vessels that have complex internal structures or mixing equipment. An integrated graphic display provides easy readout viewing and the user-friendly setup menu supports a wide range of languages for quick setup in virtually any region of the world. Housed in an explosion-proof assembly with screw-on, glass cover for quick and easy access, the SS 140XP meets the requirements for use in hazardous areas and is rated for IP67 or NEMA 4X, Class I Div. I Group A, B, C, & D ratings ...

Contact-free DC-Operated Rotary Position Sensors Features 0.1% Linearity

 

Pennsauken, NJ, October 11, 2007 - Macro Sensors introduces its new RS 1500-120 series of Fractional-Turn Contactless Rotary Position Sensors for measuring the angular displacement of rotating elements such as quarter-turn ball and butterfly valves, air flow dampers, and diverter gates used in packaging and postal sorting machinery. Available as the RSE 1500-120 with a 24 V DC input and a 0-to-10 V DC output, or as the RSI 1500-120 with a 2-wire 4-20 mA loop-powered transmitter I/O, these units are adaptable to a wide variety of industrial automation and process control applications.

 

Although their shafts can rotate a full 360, the RS 1500-120 rotary position sensors utilize contactless inductive technology to measure shaft angle position over a nominal range of 120 with excellent accuracy and repeatability and exceptional reliability. These units exhibit a linearity error of less than 0.10% of full range output, have an IEC IP-66 environmental rating, and operate at temperatures from 0F to 185F (-20C to 85C) ...

Sensors Take Accuracy to New Heights in De Havilland Pilot Watches

 

Pilot watches made by Swiss De Havilland use VTI Technologies' pressure sensors for precision barometer and altimeter functions. The De Havilland pilot watches record times of take-offs and landings, flight duration, allowing the user to register both block to block and total flight time.

 

De Havilland pilot watch models DH-01 and DH-02 have been developed specifically for pilots by pilots, says Jean-Daniel Carrard, aviator and managing director of JDC Electronic SA. "De Havilland watches feature unique innovations that enhance flight data accuracy and usability of the watch. The DH-02 model is equipped with VTI's SCP1000 pressure sensor enabling altitude to be estimated to the accuracy of one foot. This entirely new interface, based on a rotating bezel, allows the user to adjust altitude and pressure (as in instrument panels) and to set the time - one of the intelligent features seen for the first time in the watch. Also, a completely new proprietary control system based on the magnetic fields has been introduced to give precise control of the functions of De Havilland watches" ...

Multifunction Small Format Measuring Instrument

 

BASEL Following on from the success of its MSR 12 hand-held measuring instrument, technology company MSR Electronics GmbH, Henggart, introduces a further miniaturised datalogger, the MSR 145. The thumb-sized MSR 145 can store over 2,000,000 measurement parameters and is capable of capturing and saving a range of different physical measurements simultaneously.

 

The MSR 145 (MSR = Modular Signal Recorder) combines all the necessary sensors for measuring and recording the most important physical quantities in the smallest possible space. It has a temperature sensor, a humidity sensor with integrated thermometer, a pressure sensor with integrated thermometer and a 3 axis acceleration and position sensor (X, Y and Z axes). The measurement parameters can be transferred to a PC both during the measurement process and later. Three further ports are available for optional use, two of which can be used as analogue inputs and one as a digital trigger input (e.g. for external sensors). Whether as a supplement to the MSR-12 or as a stand-alone miniaturised datalogger, the new MSR 145 impresses with its robust design and versatile fields of application ...
