The adjustable constant temperature controller circuit is asbelow. REF01E provides TMP17 with 10V high steady power supply, it can obtain a voltage singal from resistor R1, the voltage is in direct proportion t0 the measured temperature t. AD790 is a voltage comparator. If t represents the measured temperature and to represents the set value, when t>t0, the output of constant temperature controller is low level, when t<t0, it is high level. The value of to can be adjusted by potentiometer PR. C1 is denoising capacitance, C2 is accelerate capacitance. The output terminal of temperature control circuit controls the electric heating device by means of all kinds of actuators, then to achieve temperature control.
