Abstract
A device having two mutually spaced sensor loops is provided. The device includes a magnetostrictive sensor structure coupled to a plurality of transmitters and a plurality of receivers, and along which a magnet that is secured to the rotating component moves. Each sensor loop has a shape corresponding to a rotating direction of the rotating component. Two saturation zones are in both sensor loops. Each transmitting element is provided for simultaneously coupling two current pulses in opposite direction into one respective sensor loop. Each receiving element is positioned to receive a reflected pulse by the magnet at the respective saturation zone. The receiving elements are connected to evaluation electronics configured to for determine an angular position of the rotating component based on transit times for the current pulse to travel along the respective sensor loop from the respective transmitting element to the respective saturation zone and for each reflected pulse to travel along the respective sensor loop from the respective saturation zone to the respective receiving element.
