Abstract

Die vorliegende Erfindung offenbart einen Kraftsensor (1) sowie ein Verfahren zum Erfassen von Zug- und/oder Druckkräften. Der induktive Kraftsensor (1) besteht aus einem ringförmigen Spulenkern (10) mit einem Luftspalt (20). Die an dem Spulenkern (10) in dem Befestigungspunkten (12) angreifenden Zug- oder Druckkräfte verändern die Breite des Luftspalts (20), so dass aus einer sich daraus ergebenden Induktivitätsänderung des Kraftsensors (1) die angreifenden Kräfte bestimmbar sind.
