Abstract

PURPOSE: To ensure a correspondence to various temperature controls from a wide range to a microranges, by using the differential amplifying circuit to which the negative feedback is applied.
CONSTITUTION: The voltage eT corresponding to the temperature to be controlled and detected through the temperature detecting circuit A plus the voltage ed set through the temperature setting circuit B are supplied to the differential amplifying circuit C having a negative feedback operation. The output eO of the circuit C drives the driving circuit to control the load 17. In such constitution of the circuit, the amplification factor of the circuit C can be varied to the set temperature Td, thus ensuring various temperature controls from a wide range to a microrange. For instance, a high accuracy is secured for the temperature control of an oven cooking tool or the like. When the resistance value of the variable register 8 for setting of temperature is set large enough, the variance of the set temperature can be reduced by the variance of the resistance value.
