PRESSURE SENSING DEVICE FOR ROTATABLY MOVING PARTS AND PRESSURE DETECTION METHOD THEREFOR

摘要

A magnetic pressure sensing device for rotatably moving parts, of the type including at least one magnetic field source element associated to said rotatably moving part and a magnetic field sensing element associated to a fixed part to measure parameters of a magnetic field determined by said magnetic field source element, said parameters of the magnetic field being a function of the pressure applied to said rotatably moving part. The magnetic field source element includes means for rotating around at least one axis the direction of said magnetic field as a function of the pressure applied to said rotatably moving part.
