Resumen
Magnetic position sensor device comprising, at least: (a) excitation means (1) comprising, in turn: - an ac generator (6) that supplies a coil (5) or primary coil, with an alternating current of a given frequency f; (b) a magnetic probe (2) comprised in a movable rod, displaceable longitudinally parallel to the axis x of the coil (5) on the outside thereof; (c) electronic means of signal processing, comprising, in turn, two distinct stages: (I) a first stage comprising a detector in phase which has as one of its inputs the signal of the probe (the response) and which supplies as output a dc signal; (II) a second stage which is a conditioning stage that adapts the output signal of the first stage to the desired levels.
