UA80934U - 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 output windings of which are connected in differential circuit, and the second pair of ferro-sensitive elements output windings of which are connected in differential circuit as well. Both pairs of ferro-sensitive elements are placed one with respect to another at distance that is equal to half-length of the source of magnetic field, and the ends of the output windings of the ferro-sensitive elements placed at one side of the source of magnetic field are connected. Additional third and fourth pairs of ferro-sensitive elements are used, those are placed at the side of the ends of the source of magnetic field, output windings of those are in pairs connected in differential circuit. The ferro-sensitive elements of each of those pairs are displaced one with respect to another by distance equal to half-thickness of the source of magnetic field. The ends of the output windings of the ferro-sensitive elements placed at one side of the axis of the source of magnetic field are connected.
