Abstract
A displacement sensor includes an induction element and sensor element. The induction element has an electrically conductive measurement track element extending along a measurement path, and two electrically conductive correction track element positioned adjacent to each other relative to the path. The sensor element is movable relative to the induction element along the measurement track element, and has a measurement coil positioned over the measurement track element and two correction coils positioned adjacent to each other relative to the path. A position change of the measurement coil on the path changes an overlap of the measurement coil and the measurement track element along the path such that an induction of the measurement coil is configured with reference to the position of the measurement coil on the measurement path. Each correction coil is positioned over a respective corrective track element such that an overlap of the correction coil over the respective corrective track element is constant.
