The detector converts the information signal and the integrator singles out constant component and gives it in the shape of quasi constant voltage on the flux-gate and on the measuring arrangement. 
     EFFECT: using of only one winding, only one circuit of excitation and a discharge practically excludes unbalance of processing of the signal and reduces requirements to identity of the elements of the processing system and this increases temperature stability and accuracy of measuring.
