A CONTACTLESS TWO-SENSOR DC TRANSDUCER – TRANSDUCTION FUNCTION ANALYSIS

Stanislaw Moskowicz

Abstract

In the paper the design and operation principle of a contactless two-sensor DC transducer is presented. The operation of the transducer makes use of the signal yielded by two fluxgate sensors based DC transducer situated at a certain distance from the wire traversed by the current to be measured. The proposed geometrical arrangement of the sensor makes the transduction accuracy less sensitive to inaccurate keeping the distance between the sensor and the wire flowed through by the current to be measured.
