Abstract

Ein Sensorkopf (2) eines Wirbelstromsensors (4) ist radial auf eine Welle (1) gerichtet. Die elektrische Leitfähigkeit der Welle (1) verändert sich entsprechend eines an der Welle anliegenden Drehmoments. Diese Änderung führt zu einer Änderung der Einkoppelstärke des Wirbelstromsensors (4), was in einer Auswerteelektronik erfasst wird. Dadurch ist es möglich, das Drehmoment der Welle (1) ohne erhebliche konstruktive Eingriffe an der Welle sicher zu erfassen.
