Device for detecting position of movable element in 2D measurement field arrangement determines resistance between element contact point with measurement field arrangement and measurement connection

摘要

The device has measurement connections (5,6) connected to a resistance measurement field (2) at two or more different points and connected to measurement devices (V2,V3). An electrical parameter is used to determine the resistance between a point (P) at which the element contacts the measurement field arrangement and the relevant measurement connection.
