Abstract
The disclosure relates to a magnetic position sensor including at least one permanent magnet. The disclosure also relates to a magnetic device for detecting a torque between a first shaft and a second shaft that are connected via a torsion bar. The aim of the disclosure is to provide a device for determining the multi-periodic absolute position of a magnetized unit. The subject of the disclosure is therefore a magnetic position sensor including at least the following: a magnetized unit, a first magnetosensitive probe and a second magnetosensitive probe. The second magnetosensitive probe is capable of measuring a number of complete rotations of the magnetic field in an absolute, incremental and reversible manner so as to determine a second datum relating to the position of the magnet, whether or not this second magnetosensitive probe is powered. The sensor further includes a module for calculating the absolute position of the magnet on the basis of the first and second data coming from the first and second probes respectively.
