Inductive linear sensor and inductive angle sensor

摘要

Described is an inductive linear sensor and an inductive angle sensor for a motor vehicle with an oscillator circuit that generates a periodic alternating voltage signal and couples it into an excitation coil, with several receiving coils and an evaluation circuit for evaluating the signals induced in the receiving coils and a movable inductive coupling element, which is the strength the inductive coupling between the excitation coil and the receiving coils is influenced, starting from an inductive coupling element with a simple geometric shape, the geometric shape of at least one of the boundary lines of the inductive coupling element is changed, so that errors that occur due to the inhomogeneities of the magnetic field generated by the coupling element , be minimized.
