| 摘要 |
The invention discloses a magnetic detector arrangement with a magnetic sensor element (2) and a magnetic means (4) for imposing a magnetic field on the magnetic sensor element (2) , and also comprises magnetic deflector means (7) operable to direct an external magnetic field in a direction substantially parallel to the magnetic sensor element (2) . The magnetic means (4) comprise two equally polarised magnets positioned at a predefined distance apart next to each other with the polarisation in the same direction so that a magnetic field generated in operation by the two magnets is forced to be substantially parallel to the magnetic sensor element (2) . The advantage of the invention is to provide a magnetic detector arrangement with a reduced sensitivity to an outer magnetic field. |
