Title
(DE) Drehwinkel-Potentiometer
(EN) Rotation angle potentiometer
Abstract
(DE) Ein Potentiometer für die redundante Messung des Drehwinkels einer Welle (2) gegenüber einem feststehenden Teil weist auf einer feststehenden Scheibe (1) zwei konzentrisch zueinander angeordnete kreisbogenförmige Widerstandsbahnen (4, 5) auf. Auf einer zu der feststehenden Scheibe parallel angeordneten und zusammen mit der Welle (2) umlaufenden Scheibe (3) sind konzentrisch zueinander zwei kreisringförmige Kollektorbahnen (14, 15) angeordnet. Zwei mit den Kollektorbahnen (14, 15) verbundene Stromabnehmer-Schleifer (17, 18) stehen in Kontakt mit den beiden Widerstandsbahnen (4, 5). An zwei auf der feststehenden Scheibe (1) befestigten Anschlußfahnen (10, 11), die über zwei Stromabnehmer-Schleifer (12, 13) mit den Kollektorbahnen (14, 15) in Kontakt stehen, werden zwei redundante Meßwerte abgegriffen.
(EN)

A potentiometer for the redundant measurement of the rotation angle of a shaft (2) with respect to a stationary part has two resistance tracks (4, 5) on a stationary disc (1), which resistance tracks (4, 5) are in the form of circular arcs and are arranged concentrically with respect to one another. Two collector tracks (14, 15) in the form of circular rings are arranged concentrically with respect to one another on a disc (3) which is arranged parallel to the stationary disc and rotates together with the shaft (2). Two current pick-off wipers (17, 18) which are connected to the collector tracks (14, 15) are in contact with the two resistor tracks (4, 5). Two redundant measurements are picked off on two connecting tabs (10, 11) which are mounted on the stationary disc (1) and make contact with the collector tracks (14, 15) via two current pick-off wipers (12, 13). <IMAGE>
