Abstract:
The present disclosure relates to a sensor assembly for simultaneously capturing an angular position and a torque of a rotatable shaft. The sensor assembly comprises, for determining the angular position, a main body, two additional bodies, which are arranged coupled for rotation on the main body, and two angle resolvers, which are arranged on a circuit board in the immediate vicinity of the additional bodies. In this arrangement, the angles of the additional bodies are determined by the angle resolvers and passed as an angle signal to an evaluation unit arranged on the circuit board. The sensor assembly further comprises a direct coating, which captures a torque signal from the rotating shaft and passes this signal over a connection line to the evaluation unit. The connection line has a section wound multiple times around the shaft to permit a rotation of the shaft by at least +/−900°.
