Abstract

Die Erfindung betrifft eine Sensoranordnung für eine in einem Magnetlager (2) gelagerte Welle (1), umfassend eine magnetische Abschirmung, die unter Ausbildung eines magnetisch abgeschirmten Bereiches das Magnetlager (2) abschirmt, eine in dem magnetisch abgeschirmten Bereich an der Welle (1) angeordnete magnetische Codierung (10), und mindestens einen Empfänger (11), der mindestens eine Änderung eines Magnetfeldes der magnetischen Codierung (10) erfasst. Die vorgenannte Sensoranordnung löst erfindungsgemäß die Aufgabe, für eine in einem Magnetlager (2) gelagerte Welle (1) eine Sensoranordnung anzugeben, die anhand einer magnetischen Codierung (10) der Welle (1) die Position der Welle (1) möglichst in der Nähe des Magnetlagers (2) zu erfassen ermöglicht.
