Abstract
A measuring arrangement is provided with a magnetic field-sensitive sensor (2), which includes a body (10) formed of a magnetic material. The body has a continuous recess (12) and a wall (26) defining same. The sensor (2) has at least one electric conductor (5), which extends between the ends and is passed through the recess (12). A magnet (22), which can be moved relative to the body (10), provides a magnetic field by which the permeability of the body (10) can be varied as a function of the distance between the body (10) and the magnet (22). An analysis means (4), which can be or is connected to the conductor (5) and by which the change in the permeability of the body (10) can be detected. The conductor (5) does not loop around the wall (26).
Claims19
A measuring arrangement comprising:
- a magnetic field-sensitive sensor comprising a body formed of a magnetic material, which has a continuous recess and a wall defining said continuous recess, an electric conductor, which extends between two ends of said body and passes through the recess and a magnet, which is movable relative to the body and by the magnetic field of which the permeability of the body can be varied as a function of a distance between the body and the magnet;
- and
- an analysis means, which can be or is connected to the conductor, said analysis means for detecting change in the permeability of the body, wherein said conductor does not loop around the recess.
A magnetic field-sensitive sensor for a measuring arrangement the magnetic field-sensitive sensor comprising:
- a body formed of a magnetic material, the body having a continuous recess and a wall defining same;
- and
- an electric conductor, which extends between two ends and is passed through the recess, wherein the permeability of the body can be varied as a function of an external magnetic field, wherein the conductor does not loop around the wall.
