Description

This paper presents an analysis of the null voltage compensation of differential transformer which has been applied to the measurement of linear displacement.<BR>A paralleled potentiometer, which has generally been used for null compensation, has not enough stability on zero position. The author has been pushing a study to minimize the zero shift caused by null compensation and has developed, as its result, another circuit which consists of a paralleled potentiometer and a small capacitor connected between the slide contact of the potentiometer and the neutral point of secondary coil of the differential transformer. With this new circuit, zero shift was reduced by approximately one eightieth from that of an ordinary circuit.
