Abstract

PURPOSE: To reduce the cost of device, by enabling to use a thermister which has long response time constant, through the provision of a preceding rate element for response delay compensation for a process variable signal.
CONSTITUTION: A set value TUP is set with a set value setter 4. An output TWOB of a process variable signal detector 5 is inputted to a preceding rate and differentiator 9 to obtain TWOV, which is operated with the TUP to obtain a deviation TER. It is inputted to an output signal controller 8. An output signal TC is inputted to a control variable process 1. The insertion of the device 9 allows the use of a thermister having alow response time for the detector 5, allowing to suppress the overshoot and to reduce the settling time with a low cost.
