UA68104U - Weight-measuring sensor - Google Patents

Abstract

A weight-measuring sensor includes a magnetic field source placed between the first pair of ferrosensitive elements output windings of which are connected by differential circuit, and the second pair of ferrosensitive elements output windings of which are connected by differential circuit as well, at that both pairs of ferrosensitive elements are placed one with respect to another at distance equal to half of length of magnetic field source. The ends of the output windings of ferrosensitive elements placed at one side of the source of magnetic field are connected. Besides that, two additional unit magnetic field sources are placed, those are connected with same poles to the main source of magnetic field. Additionally, a third pair of ferrosensitive elements is included, this is placed at the line of magnetic neutral of the main source of magnetic field in one plane with placement of the first and the second pairs of the ferrosensitive elements. At that the output windings of the ferrosensitive elements of the third pair are connected by differential circuit and connected in series to the output windings of the first and the second pairs of ferrosensitive elements.
