Method and device for measuring valve stroke

The method involves producing electrical output signals by a sensor device (MS) i.e. magneto-resistive sensor device, corresponding to a valve stroke of a valve (VA) under the influence of a ferromagnetic periodically modulated structure. A periodically sinusoidal modulated voltage signal (SIN) is p...

Beschreibung
Zusammenfassung:	The method involves producing electrical output signals by a sensor device (MS) i.e. magneto-resistive sensor device, corresponding to a valve stroke of a valve (VA) under the influence of a ferromagnetic periodically modulated structure. A periodically sinusoidal modulated voltage signal (SIN) is provided as one electrical output signal with a period (P). An appropriate cosinusoidal modulated voltage signal (COS) is provided as the other electrical output signal. The sensor device is integrated in a wall of a shell-shaped valve guide device (FH). An independent claim is also included for a device for detecting a valve stroke.
