UA84594U - 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. The finishes of the output windings of the ferro-sensitive elements placed at one side of the source of magnetic field are connected together, two additional single sources of magnetic field, one of those is connected with the same pole to the main source of magnetic field. Between the main and the other additional sources of magnetic field an identical to the main one source of magnetic field is placed, this is connected to those with the similar poles. Both pairs of ferro-sensitive elements are placed one with respect to another at distance equal to the length of the main source of magnetic field, and the third pair of ferro-sensitive elements is placed at the side of the poles of the additional sources of magnetic field. The output windings of those are connected in differential circuit and connected in series to the output windings of the main pairs of the ferro-sensitive elements.
