POSITION OR ELEMENT WEAR DETECTION DEVICE

摘要

1. Apparatus for detecting the position of one mechanical member with respect to another, of the type in which a magnetic core (1) whichis fixed to one of the members (27) engages into a coil (3) which is attached to the other member (28) characterized in that there are provided means (7, 11) for passing a stabilized direct current through the coil (3), for cutting it off, and for collecting in a capacitor (13) the energy previously stored in the coil (3) by passing the current through a diode (12) connected in series with the coil (3) and the capacitor (13).
