A weight-measuring sensor includes a magnetic field source placed between the first pair of the ferro-sensitive elements, second pair of ferro-sensitive elements, output windings of those are connected by differential circuit as well. Both pairs of ferro-sensitive elements are placed one from another at distance equal to half of length of the magnetic field source. The ends of the output windings of the ferro-sensitive elements placed at one side of the source of magnetic field are connected. Additional two sources of magnetic field are placed at two sides of the main source of magnetic field and connected to it with non-magnetic links. The device has a third pair of ferro-sensitive elements placed at the line of magnetic neutral of the magnetic field sources in one plane with placement of the first and the second pairs of ferro-sensitive elements. The input windings of the ferro-sensitive elements of the third pair are connected by differential circuit and are connected in series to the output windings of the first and second pairs of ferro-sensitive elements. |
