Rotary transducer for transmission of static signal, has rotary part with conductor arrangement loaded by transmission device, and stationary part with coupler device loaded by receiving device, where coupler device has sensor

摘要

The transducer (3) has a rotary part (1) with a transmission conductor arrangement (6) loaded by a transmission device (8) of the rotary part, and a stationary part (2) with a receiving coupler device (7) loaded by a receiving device (9) of the stationary part, where the receiving coupler device has a giant magneto resistance (GMR)-sensor. The transmission device produces a difference signal with a constant component. The transmission conductor arrangement has a conduction loop with a conductor arranged along a path of movement.
