Zusammenfassung:A linear displacement sensor includes an induction element, measuring sensor element, and correction sensor element. The induction element has a first side with an electrically conductive measuring track running along a measurement path. The measuring sensor element is positioned over the first side, is movable relative to the induction element along the path, and includes a measuring coil positioned over the measuring track such that an overlap between the measuring coil and the measuring track changes along the path so that an induction of the measuring coil is dependent on a position of the measuring coil on the path. A second side of the induction element has an electrically conductive correction track running along the path. The correction sensor element is rigidly connected to the measuring sensor element, is positioned over the second side, and has a correction coil with a constant overlap with the correction track along the path.
