<p>A potentiometer for the redundant measurement of the rotation angle of a shaft (2) with respect to a stationary part has two concentric arc-shaped resistance tracks (4, 5) on a stationary disc (1). Two concentric circular collector tracks (14, 15) are arranged on a disc (3) which is parallel to the stationary disc and rotates with the shaft (2). Two collector brush grinders (17, 18) are in contact with the two resistance tracks (4, 5). Two redundant measurements are made at two terminal lugs (10, 11) attached to the stationary disc (1), which are connected to the collector tracks (14, 15) through two collector brush grinders (12, 13).</p> |
