SYSTEM FOR DETERMINING THE POSITION OF AN ORGAN

摘要

The invention relates to a system comprising an encoder (1) comprising a main magnetic track (2) and a secondary magnetic track (3) and a sensor (4) having two patterns (5) of sensitive elements which are able to detect signals delivered by the tracks (2, 3) of the encoder (1), each pattern (5) being intended to be placed at a reading distance from a track (2, 3) to form a signal representative of the position of said track , said sensor further comprising a device (6) for processing the signals originating from the patterns (5) to determine the position of the organ, the sensitive elements of a first pattern (5) being based on a magnetoresistive material of which the resistance varies according to the magnetic signal of the track (2, 3) to be detected, the sensitive elements of the second pattern (5) being of a different nature with regard to the technology of detection of the magnetic signal delivered by the track (3, 2) to detect.
