The characteristics of the detecting unit of displacement are closely studied, following the previous report.
The minimum value of the resultant valtage, i.e. emin, which is closely connected with the accuracy of control, is reduced almost to zero by means of a simple CR circuit not to interfere with the practical use, and for tele-metering or remote controling use emin iss similarly reduced almost to zero by a simple electronics circuit. Characteristics of these circuits are examined and the feature of this detecting unit is detailed comparing with that of the moving core type deferential transformer which has become of general use for the detection of displacement.
