Abstract (en)
[origin: WO2017153074A1] The invention relates to a displacement sensor (10) comprising an induction element (14) having at least one electrically conductive measurement track element (20a, 20b), which extends along a measurement path (M); a sensor element (12), which can be moved relative to the induction element (14) along the at least one measurement track element (20a, 20b); wherein the sensor element (12) comprises at least one measurement coil (24a, 24b), which is arranged over the at least one measurement track element (20a, 20b); wherein an overlap of the at least one measurement coil (24a, 24b) and the at least one measurement track element (20a, 20b) along the measurement path (M) changes in such a way that an induction of the at least one measurement coil (24a, 24b) depends on a position (y) of the measurement coil (24a, 24b) on the measurement path (M); wherein the induction element (14) has two electrically conductive correction track elements (20c, 20d), which are arranged adjacent to each other with respect to the measurement path (M); and wherein the sensor element (12) has two correction coils (24c, 24d), which are arranged adjacent to each other with respect to the measurement path (M) and each over one of the two correction track elements (20c, 20d) and the overlap of which with the correction track elements (20c, 20d) along the measurement path (M) is constant.
