Magnetic position sensor using a flux collector and measurements of the magnetic field direction

摘要

Relates to a magnetic position sensor using a flux collector and measurements of the magnetic field direction, the present invention, the amplitude ratio of the two components by adjusting a flux collector amplitude of the magnetic induction components of the two measured positions and the same single In order to propose to about 1, the flux collector of the one or more pairs and (3) detecting one or more elements that detect the magnetic field direction and (1) one or more permanent magnet for generating a magnetic field (2a, 2b and a), permanent magnet (1) is movable in the displacement direction, to provide a non-contact position sensor which indicates the direction of magnetization can be varied continuously along the displacement direction. (2a, 2b) is, at least some of the ends (8, 9) extend substantially along the displacement direction of the magnet (1) the flux collectors. Ends (2a, 2b) of the flux collector of the pair (8,9) defines an air gap in a direction along the displacement direction of the magnet (1) and (7). Detection element (3) is disposed substantially equidistant two ends from (8,9) air gap (7) outside.
