Summary: | The device (1) has a collection point (16) provided for collecting impurities in fluid. Permanent magnets are provided for producing a magnetic field at the collection point. A magnetic flux guiding element of the device is movable via supplying current to a coil, where magnetic field thickness at the collection point is changeable via movement of the element. A concentration element is provided for concentrating magnetic flux at the collection point. The permanent magnets and the coil are arranged co-axial to each other. A housing element (36) comprises a blind hole for arranging the magnets.
Die Erfindung betrifft eine Vorrichtung (1) zum Erfassen der Verunreinigung eines Fluids, insbesondere Vorrichtung (1) zum Erfassen von metallischen Partikeln (10) in einem Fluid, wobei die Vorrichtung (1) aufweist eine Sammelstelle (16) für das Ansammeln der Verunreinigung des Fluids, einen Permanentmagneten (12) zum Erzeugen eines magnetischen Feldes an der Sammelstelle, und eine Spule (20), dadurch gekennzeichnet, dass durch ein Bestromen der Spule (20) ein Element der Vorrichtung (1) bewegbar ist, und dass durch die Bewegung des Elements die magnetische Feldstärke an der Sammelstelle (16) veränderbar ist. |
