The working principle of thermostat is based on the synergistic effect of temperature sensor, controller and actuator.
First of all, the temperature sensor is the core component of the thermostat, which can sense the temperature change of the system or equipment and convert it into an electrical signal. Common temperature sensors include thermocouples, thermistors and infrared sensors. The choice of sensor depends on the requirements of the specific application.
Secondly, the controller is the intelligent part of the thermostat, which receives the electrical signal from the temperature sensor and makes judgments and decisions according to the preset temperature range and requirements. The controller usually includes microprocessor, circuit and algorithm, which can monitor, compare and control the temperature.
Finally, the actuator is the output part of the controller, which adjusts the working state of the system or equipment according to the instructions of the controller to achieve the purpose of temperature control. The actuator can be solenoid valve, motor, heater or cooler, etc. The specific choice depends on the requirements of the application.
