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).
