Abstract
A sensor for measuring torque and position of a shaft having an internal torsion bar. The sensor has a torque sensor, located in the housing and connected to the shaft. The torque sensor has a rotor in electrical contact with a first and second resistive track disposed on an opposed disc. A position sensor is located in the housing and is connected to the shaft. The position sensor has a third contactor mounted to the housing in electrical contact with a third resistive track located on the disc. Several electrical terminals are located in the housing and are electrically communicated with the contactors to provide an electrical signal indicative of the torque and position of the shaft to an external electrical circuit. A slip ring is attached between the rotor and the housing. The slip ring has a fourth and fifth contactor in contact with the torque sensor. The slip ring is adapted to electrically connect the torque sensor to the electrical terminals.
