Date Jan. 12, 1989.A potentiometer for the redundant measurement of the angle of rotation of a shaft compared with a fixed member has two resistance paths located concentrically with each other on a fixed disk. Two collector paths having the shape of circular rings are located concentrically with each other on a disk situated parallel to the fixed disk and rotating together with the shaft. Two slide contacts connected with the collector paths are in contact with the two resistance paths. Two redundant measured values are tapped at two terminal contacts fastened to the fixed disk that are in contact with the collector paths through two slide contacts.
