POSITION SENSOR AND MEASURING ARRANGEMENT

摘要

In order to facilitate mounting, servicing and replacing a sensor arrangement for filling level determination in a tank or a position determination of the piston in an operating cylinder with a magnet field sensing sensor and in order to prevent it from being damaged it is proposed to arrange a rod shaped sensor arrangement on an outside of the magnetizable wall and a magnet interconnection made from plural interconnection magnets or interconnection sections in particular a rotation symmetrical magnet interconnection in an interior of the cylinder or of the tank, thus optionally in the liquid included therein like e.g. hydraulic oil. Through a corresponding selection of the pole orientation of the individual interconnection magnets or interconnection sections the operating field of the magnet interconnection is strong enough so that it penetrates the magnetizable wall and reaches the sensor arrangement.

主权项

1. A magnetic field sensitive position sensor (20) that measures in a measuring direction (10), the position sensor (20) comprising:
a sensor arrangement (1) which extends in the measuring direction (10); and a magnet interconnection (4) that is moveable in the measuring direction (10) relative to the sensor arrangement (1) wherein a position of the magnet interconnection (4) in the measuring direction (10) is detectable by the sensor arrangement (1), wherein the magnet interconnection (4) is either integrally configured with plural interconnection sections (2a, b, c) or configured in plural elements with plural interconnection magnets (5a, b, c), pole orientations (6a, b) of the interconnection sections (2a, b, c) or interconnection magnets (5a, b, c) are different, and; the interconnection magnets (5a, b, c) or the interconnection sections (2a, b, c) are arranged at a distance from each other, so that they contact each other so that their magnetic fields overlap.
