There are three channel of temperature sensor in the sensor box. One channel is for reading hood temperature to remain the temperature at setting temperature.
Another temperature sensor is an individual circuit for prote-ction only.
The third sensor is used to compare the reading with the other two sensors.
If the reading of sensor is differ from 0.8 degree, the alarm will be triggered
The incubator is equipped with both thermocouple and mechanical temperature switch to protect the heating source of heating system and evaporator.
Thermocouple is reading the real time temperature and limits the temperature in safety range bwbedback temperature value to control module.
While, mechanical temperature switch is in series circ-uits, if the heating source temperature goes abnormal level, temperature switch cuts off the circuit physicaliy.
