IT’S PLUG-&-GO FOR TORQUE TRANSDUCER
September 1st 2005 A dynamometer for testing 180 motors/hour for vehicle electrohydraulic powerassisted steering, uses a non-contact torque transducer from Sensor Technology for ensuring accuracy of readings.
A Tier 1 supply company uses the dynamometer as part of a highly automated test cell that includes conveyors to deliver and remove motors to be tested. Such automation is crucial for maintaining the cycle time, repeatability and validity of the tests.
Torqsense transducers do not need to be physically connected to the test piece via a complicated set of slip rings which would be time consuming to assemble and dismantle between each motor.
The transducer is a 1Nm 310 series Torqsense, an intelligent unit with all signal processing electronics built into its main body, giving it a plug-&-go capability.
The frequency dependent strain gauge operates at ultrasound frequencies and consists of a piezoelectric comb on the test shaft that monitors variations in resonance frequency as the torsional load varies. An RF link is used for wireless transmission of signals to an adjacent pick.

New for 2008 is TorqSense RWT 330/340series, designed for use in applications where space is limited, and provides non-contact measurement of torque, speed, power and position of rotating shafts, such as machine drives, drive shafts for pumps, fans, mixers etc, and in the critical axes of test rigs...
