How does the temperature controller work?
Through the electrical signal fed back by the temperature probe or thermocouple, the temperature controller converts the obtained electrical signal into a temperature value, and according to the set temperature value, controls the heater on and off to achieve the control temperature range:
1. When the temperature probe or thermocouple is subjected to temperature changes, a weak current will be generated;
2. When the temperature controller receives the electrical signal from the temperature probe or thermocouple, it will convert the current signal into the temperature value according to its current size;
3. In order to control the temperature range, people will set a temperature range on the temperature controller, and the temperature controller will reach the upper limit set by the temperature controller according to the temperature converted by the electrical signal transmitted from the temperature probe or thermocouple. When the limit value is set, the temperature controller will cut off the power supply of the control circuit that controls the heater, so that the heater stops heating. When the temperature value drops to the lower limit set by the temperature controller, the temperature controller will turn on the control heater The control circuit power supply, and the heater work for heating, as long as the thermostat is continuously powered, this process will cycle again and again.
In summary, the working principle of the temperature controller is the electrical signal fed back by the temperature probe or thermocouple. The temperature controller converts the obtained electrical signal into a temperature value, and controls the heater to turn on according to the set temperature value. And disconnect to reach the control temperature range.
