Abstract
Given a device for contact-free position measurement, a movable or resting part that represents a load in an alternating field or that is designed as an element emitting field lines is spatially neighbored by a sensor carrier that exhibits a plurality of individual sensors that are electrically and spatially separated from one another, whereby each of said individual sensors can be applied to direct or alternating voltage, and whereby an interrogation and evaluation means is provided, to which each of the individual sensors is connectable for the purpose of identifying its output signal that is dependent on the position of the positionally variable or resting position indicator.
