Non-contact torque sensor is one in a million

Thu, 07 Jun 2007 19:34:35 +0200

At the heart of the TorqSense sensor is pair of tiny, interleaved, comb-shaped arrays laid onto one end of a piezoelectric substrate. By passing an alternating voltage across the terminals of these arrays, surface waves are produced in the substrate. The waves are received by a similar array at the other end which converts them back into an electric signal.

Level measurement in control

Wed, 06 Jun 2007 23:59:09 +0200

Vega offers a range of rugged level measurement devices designed to withstand pressure shocks, abrasion, moisture, vibration, pollution and condensation. Tough housings protect the fully potted electronics from the moist, humid ambient conditions and the harsh cleaning processes typical of this industry. To measure up to the increasing demands on operational reliability, SIL (Safety Integrity Level) classified instruments are available.

Sonus supplies small ultrasonic sensors

Mon, 04 Jun 2007 19:47:22 +0200

These sensors are suitable for installation in the smallest spaces or for the assembly of several sensors in the tightest places. Ultrasonic technology permits objects to be detected regardless of their colour or transparency. Due to their small mass of less than 4 grams, the new Sonus sensors are well suited for installation in all light, fast-moving handling units.

All-in-one torque sensor targets OEMs

Mon, 04 Jun 2007 19:34:35 +0200

Unlike traditional slip-ring transducers, the TorqSense sensors provide a simple non-contact technology for measuring the power in drive shafts and other rotating elements. Torsion is sensed by a pair of SAW strain gauges bonded to a shaft at right-angles to each other. One senses compression and the other tension, and this information is transmitted via a radio frequency couple to the decoding electronics which generates outputs for torque, speed, power and angle.
