Abstract

PURPOSE: To enable a plunger to be maintained always at a right position, by means of detecting the change of position of the plunger against a movable york circuit, and of regulating the current of the movable coil.
CONSTITUTION: A plunger assembly 5 connecting to the control rod within a pressure tube, is controlled in the positin by the magnetic combination of a movable coil york assembly 6, and a relative dis placement detector 11 is set up at the coil 6. Connections 1,2 connected to the coil 6 from a current feeding circuit 13, and a relative position signal 14 from the displacement detector 11 is conducted to an connection 3, and emerges a control rod position signal 17 by means of receiving at an amplitude compensating / temp. correccting / adding circuit 15 along with an absolute position signal. A compensating current for the purpose of correcting to a right position is flowed on the basis of te change of impedance of a circuit 13 due to the relative positon displacement and a signal from th detector 11 to the circuit 13
