Rotary Torque Transducer from HITEC Sensor Developments

HITEC Sensor Developments' rotary torque transducers are sensors capable of measuring rotating drive torque using a conventional shaft-to-shaft configuration for in-line placement. The unique design includes a digital non-contact wireless system that supplies power to the rotating electronics mounted on the shaft and transmits the signal back to the receiver in digital format. The torque signal is then signified as a calibrated high level analog voltage. The sensors feature high frequency response, high rotational speed, and high accuracy. These sensors can also be delivered with an optical encoder to measure speed or angle.
