Abstract

Ein berührungslos arbeitendes Wegmesssystem mit einem eine mit Wechselstrom beaufschlagbare Messspule (1) aufweisenden Sensor (2), wobei die Messspule (1) mindestens zwei Spannungsabgriffe (7) aufweist, mit einem elektrisch und/oder magnetisch leitenden, dem Sensor (2) zugeordneten Messobjekt (4) und mit einer Auswerteschaltung (3), wobei der Sensor (2) und das Messobjekt (4) in Längsrichtung der Messspule (1) relativ zueinander verschiebbar sind, dadurch gekennzeichnet, dass das Messobjekt (4) mindestens eine die Impedanz der Messspule (1) zwischen zwei Spannungsabgriffen (7) beeinflussende Markierung (8) aufweist, so dass die Auswerteschaltung (3) ein mit der Position des Messobjekts (4) in Bezug auf die Spannungsabgriffe (7) korrelierendes Ausgangssignal (9) liefert.
