SUPERIMPOSED FERROPROBE SHUNT Russian patent published in 2017 - IPC G01R33/02 

FIELD: physics.

SUBSTANCE: device contains a core of a material with a magnetic permeability closed up for the excitation flux, exceeding the conductivity of the article material by tens or more, is made in the form of a truss with transverse arched magnetic circuits with two contact pads connected by a longitudinal magnetic bearing windings of the excitation, measurement and feedback applied to them. Between the longitudinal magnetic circuits of the superimposed ferroprobe shunt core, parallel to it, a ferroprobe insulated from the ferromagnetic material with its excitation windings and a measuring one is installed, and its negative feedback winding simultaneously covers the longitudinal magnetic circuits of the superimposed ferroprobe shunt core and the ferroprobe.

EFFECT: increasing the noise immunity of the superimposed ferroprobe shunt.
