Inductive displacement sensor (position encoder, pickup)

An inductive displacement sensor (so-called short-circuiting ring sensor) is proposed, by means of which a mechanical displacement can be converted into an analog electric output variable. The sensor consists of an open core on which there is mounted a fixed coil, and the mechanical displacement to be detected is transferred to a single or double short-circuiting ring which is supported displaceably without contact on the core. In order to achieve high flexibility, in particular in the shaping and the characteristic of the sensor, use is made in this case of a core made from packed (stacked) metal glaze (enamel). It is possible in this way to implement displacement sensors, phase-angle sensors and the like.
