Abstract:
A contactless analog sensor of angular offset, comprising:a first portion forming a detector, comprising at least one substrate plate carrying at least one flat spiral winding, at least one core layer of a material of high magnetic permeability and low saturation field, on at least a portion of said winding, the detector being adapted to coact with a device for processing the electric signal measured at the terminals of the winding, two rotors each comprising at least one magnet, disposed along a predetermined angular sector, the rotors being movable about a same axis identical to the axis of the winding, each magnet generating in the plane of the core layer a magnetic field of a value greater than the saturation field of said core layer over at least a portion of the surface of the winding, wherein the detector comprises two core layers on opposite sides of the winding.
