DEVICE, SYSTEM AND METHOD FOR DETERMINING A POSITION OF A MAGNET

A magnetic sensor system comprising a magnet and a sensor device. The magnet has a shape and is movable along an axis (A) between a first position (z1) and a second position (z2), and is optionally also rotatable about this axis. The magnetic sensor device comprises a plurality of magnetic sensitive...

Beschreibung
Zusammenfassung:	A magnetic sensor system comprising a magnet and a sensor device. The magnet has a shape and is movable along an axis (A) between a first position (z1) and a second position (z2), and is optionally also rotatable about this axis. The magnetic sensor device comprises a plurality of magnetic sensitive elements for measuring at least two orthogonal magnetic field components or at least two orthogonal magnetic field gradients, and a processing circuit for determining an axial position of the magnet or whether the magnet is located in said first or second position (z1, z2) based on the first and second magnetic field components or gradients, and optionally also for estimating or calculating an angular position of the magnet. A method of determining said axial and/or angular position. A magnetic sensor device.
