UA80936U - Weight-measuring sensor - Google Patents

Abstract

A weight-measuring sensor includes a source of magnetic field placed between the first pair of ferro-sensitive elements, and the second pair of ferro-sensitive elements. Both pairs of ferro-sensitive elements are placed one with respect to another at distance equal to half-length of the source of magnetic field. The ends of the output windings of the ferro-sensitive elements placed at one side of the source of magnetic field are connected. The second and the third sources of magnetic field are placed at both sides of the first source of magnetic field and are connected to it by non-magnetic bridges. Additional fourth and fifth sources of magnetic field are used, those are placed at both sides of the first source of magnetic field in plane normal to the second and the third sources of magnetic field and connected to it by non-magnetic cross-shaped bridges. The additional third and fourth pairs of ferro-sensitive elements placed between the first, fourth and fifth sources of magnetic field one with respect to another at distance equal to the half-length of the source of magnetic field, with the output windings connected in pairs in differential circuit. The ends of the output windings of the ferro-sensitive elements placed at one side of the source of magnetic field are connected. The output windings of all the ferro-sensitive elements are connected in series.
