Abstract

PURPOSE:To enable a constant correcting of an operation neutral point of a tranducer, which is incorporated in a servo-device performing a process gap control, to a correct value irrespective of load flactuation and a processing speed, and to enable an automating of the device. CONSTITUTION:An amplifier 14 amplifies a potential difference between a reference signal and a feed back signal as a result of turning on a switch 16. A resistance 18 and a condenser 19 work as a time lag circuit of first order. An output volatage of the amplifier 14 can be considered to be a full direct current volatage against an answering frequency of a servo-device. Consequently, the output voltage can be considered to be a reference voltage which automatically corrects an operation neutral point of a servo- valve. If voltages across a resistance 5B are higher in comparison with the reference signal being set by a potentiometer 8, a process gap shall be selected so that it will act in such a direction as decreases the process gap, and on the contrary, if the volatage are lower, it shall be selected so that it will act in such a direction as increases the process gap. A follow-up control of the process gap can thus be performed so that the feed back signal becomes equal to the reference singal.
