Abstract: A detection device for a position sensor and to a detection system comprising such a detection device. The detection device comprises, in some embodiments, at least one primary winding and a secondary winding circuit. The secondary winding circuit has a plurality of secondary windings which are inductively coupled to the at least one primary winding during operation of the detection device, and the plurality of secondary windings is designed as two sinusoidal coils, each having a center tap.

Abstract: A rotation angle detection sensor system for a rotational body is provided, which has a reduced sensitivity against an interfering magnetic field and an interfering electric field. The rotation angle detection sensor system comprises an encoder structure that is attached to the rotational body of a machine and is movable along with this rotational body. A stationary sensor assembly is positioned opposite to this encoder structure and supplies at least one sensor signal for determining the angle position. The sensor assembly includes a first inductive element, the inductance of which is dependent on the angle position of the encoder structure.
