A force sensor includes a source of magnetic field arranged as two single permanent magnets attached to each other with same poles and placed between the first, second pairs of ferro-sensitive elements, between the third, fourth pairs of the ferro-sensitive elements placed in same way in plane normal to the plane of placement of the first and the second pairs of ferro-sensitive elements, and the output windings of each of four pairs of ferro-sensitive elements are connected in differential circuit and connected to each other in series. The first and the third pairs of the ferro-sensitive elements are placed with respect to the second and the fourth pairs of ferro-sensitive elements at distance equal to the length of the single permanent magnet. In the sensor an additional fifth pair of ferro-sensitive elements is placed, this is placed at the side of the poles of the source of magnetic field, the output windings of those are connected in differential circuit and connected in sequence to the output windings of the first-to-fourth pairs of ferro-sensitive elements. |
