Abstract:
A magnetic position sensor may include a coil arrangement, a magnetic coupling element, and a test element movable along a measurement path. The coil arrangement may include at least one transmitter coil and at least one receiver coil. The at least one transmitter coil may provide an alternating magnetic field. A magnetic flux provided via the at least one transmitter coil may at least partly pass through the at least one receiver coil. The magnetic coupling element may be configured to at least one of amplify the magnetic flux and at least partly guide the magnetic flux to the at least one receiver coil. The test element may provide a magnetic field large enough to locally magnetically saturate the magnetic coupling element. The magnetic coupling element may include at least one of a high-resistance material that is magnetizable, and a magnetizable material and a material with a specific electrical resistance.
