A weight-measuring sensor includes a source of magnetic field placed between the first pair of ferrosensitive elements the output windings of which are connected in differential circuit, and the second pair of ferrosensitive elements the output windings of which are connected by differential circuit as well. Both pairs of ferrosensitive elements are placed one with respect to another at distance equal to half-length of the source of magnetic field, and the ends of the output windings of the ferrosensitive elements placed at one side of the source of magnetic field are connected together. Introduced are two additional single sources of magnetic field and third pair of ferrosensitive elements placed at the line of magnetic neutral of the main source of magnetic field in one plane with the first and the second pairs of ferrosensitive elements. Each ferrosensitive element of the first and the second pairs of the ferrosensitive elements is equipped with an additional output winding, and the additional output windings of the first and the second pairs of the ferrosensitive elements, respectively, are connected in gradient circuit. Starts and finishes of the additional output windings of the ferrosensitive elements placed at one side of the source of magnetic field are connected together. |
