Abstract

A sensor system has a rotational angle sensor for detecting a rotational angle and a torque sensor for detecting a torque. The rotational angle sensor has a rotatable rotational angle transmitter having index elements. The torque sensor has a rotatable torque transmitter having magnets, which generate a magnetic field, and a magnetic flux unit for amplifying the magnetic field. The index elements and the magnetic flux unit are connected to one another in a rotationally fixed manner.
