Abstract
A device for contactless measurement of a displacement path, especially for the detection of position and movement, includes a sensor electronics system for the provision of an alternating current and the evaluation of alterations therein, in addition to an inductive sensor including at least one flat coil. Each coil is configured with a helicoidal conductor disposed on a plane and one of the two flat surfaces thereof forms a measuring surface which variously covers a measuring object, arranged at a distance, according to the movement thereof parallel to the measuring surface.
