Magnetic angular position sensor, has probe that determines variation of magnetic field based on angular position of ferromagnetic transmission unit made up of ferromagnetic material having specific coercive force
The sensor has a ferromagnetic transmission unit (3) to transmit rotational movement of a butterfly valve. A magnetoresistive probe (4) that determines the variation of a magnetic field based on the angular position of the unit is placed in a plane perpendicular to a rotation axis of the unit. The unit has an end segment opposite to the component, and is made of a ferromagnetic material with a coercive force between 30 and 500 Oersted.
