Patent ID: 6853179

Claim:
An arrangement for measuring field strength of a magnetic field to be measured, hereinafter referred to as measuring field, comprising: an angle sensor which can be magnetically influenced and is arranged in a predetermined alignment with field lines of the measuring field at a position of the field strength of the measuring field, which position is hereinafter referred to as measuring position, and substantially annular magnet means positioned for generating a magnetic auxiliary field at the measuring position, the magnetic auxiliary field having a predeterminable field strength in a direction deviating from that of the field lines of the measuring field at the measuring position, the auxiliary field being impressed on the measuring field and the angle sensor, so that, at the measuring position, a resultant magnetic field is formed with a field line direction that defines an angle measuring value, and so that the angle measuring value is measured by the angle sensor as a measure of the field strength of the measuring field.
