Here is to introduce a medical constant temperature box which is fixed with the temperature sensor integrated circuit, and the temperature control range is -25-+100℃.The working principle of the circuitThe medical constant temperature box consists of the temperature detection amplifier circuit, trigger, control circuit and power supply circuit, see as figure 9-40. The temperature amplifier circuit consists of the precise regulated integrated circuit IC1, temperature sensor integrated circuit IC2, computing amplifier integrated circuit IC3 (N1 and N2), resistor R1-R5 and resistors RP1 and RP2.
