Sensor Technology will take advantage of this year's mtec platform to
launch its innovative E400 non-contact, real time torque measuring
device. Using surface acoustic wave devices as frequency dependent strain
gauges to measure the change in resonant frequency caused by strain in
the drive shaft, the E400 offers digital and analogue outputs for torque,
speed and power. The unit can be connected to a PC via serial or USB
interfaces, and offers in-built peak torque sampling, storage and torque
averaging.
