The figure shows the hatch temperature control circuit. This circuit is composed of the temperature detection circuit, temperature control circuit and power outages alarm circuit etc. The temperature measurement circuit is an unbalanced bridge, and it uses gauge head A for instructions. The electric bridge is a negative temperature coefficient and has high sensitivity MF51 thermal resistor. Along with the hatch of the temperature in the cabinet constant temperature is different, the resistance of the MF51 changes. The potential of corresponding bridge two points A and B changes. It passes the 50 ttA magnetoelectric meter pointer to reflect the change of the temperature changes.
