Abstract
A noncontacting displacement sensor (,) is proposed with a measuring coil (,) to which alternating current can be applied, the measuring coil (,) having at least two voltage taps (,), with an electrically and/or magnetically conductive measuring object (,), and with an evaluation circuit (,) for evaluating and, if need be, determining an output voltage that corresponds to the position of the measuring object (,) with respect to the voltage taps (,). To provide the displacement sensor of a structural form that is as compact as possible, the measuring object (,) is arranged and displaceable in the interior of the measuring coil (,), the total impedance of the measuring coil (,) being independent of the position of the measuring object (,).
