ABSTRACT:
A device for monitoring both position and torque variations in a torque carrying member such as a shaft or flywheel functions by using a magnetostrictive torque sensor to monitor both torque variations and rotational position. The torque carrying member is structured with cutouts, protuberances, or material variations which cause the path reluctance for the flux produced by the magnetostrictive sensor to be different for different rotational positions of the shaft. This manifests as an output signal variation in the sensor which is dependent on position, and which can be used in conjunction with the magnetostrictively induced variations in signal to permit monitoring of both torque and position. The device is suitable for use with automotive engines and provides cost and space savings.
