Abstract:
1. A magnetic position sensor in at least two directions comprising: at least one moveable magnetised element and a probe comprising at least two magnetosensitive elements located substantially at the same point and each of the magnetosensitive elements measuring one of the components of the magnetic field generated by the magnetised element, the magnetised element being moveable relative to the magnetosensitive element, and at least one processing circuit that calculates a plurality of angles and moduli from algebraic combinations of the components of the magnetic field and that supplies at least two independent signals representing the position of the magnetised element in respectively each of the two directions; the magnetisation vector of the magnetised element being variable with respect to the vector normal to the surface of the magnetised element disposed opposite the probe on at least a first one of the dimensions of the magnetised element so as to define a position of the probe vis-à-vis the magnetised element in the first dimension.
