A weight-measuring sensor includes a source of magnetic field placed between the first pair of ferro-sensitive elements output windings of which are connected by differential circuit, and second pair of ferro-sensitive elements, output windings of those are connected in differential circuit as well. Both pairs of ferro-sensitive elements are placed one from another at distance equal to half of length of the source of magnetic field. The ends of the output windings of ferro-sensitive elements placed at one side of the source of magnetic field are connected. Two additional single sources of magnetic field are placed, those are attached with same poles to the main source of magnetic field. In the sensor at the side of the poles of additional sources of magnetic field the third pair of ferro-sensitive elements is placed, output windings of those are connected by differential circuit. |
