Abstract
Position sensor having a holder, a force measuring device permanently connected to the holder, and a winding device, which is permanently connected to the force measuring device and has a drive having an electric motor. Winding device is configured to unwind and wind a cable and to determine an unwinding length of the cable. Guide device permanently connected to the holder has a centering device for passing through the cable, an outlet apparatus which is mounted on universal joints and is intended to pass through the cable with a variable direction, and a position sensor for determining an angular position of the outlet apparatus. Position sensor is set up to determine position of a predetermined point of the cable relative to holder on the basis of determined angular position and unwinding length.
