The working principle of the temperature controller is to automatically sample and instant monitoring the ambient temperature through the temperature sensor. The temperature controller starts the control circuit when the ambient temperature Tamper-proof Thermostat is higher than that of the control setting value, and the control returns can be set.If the temperature is still rising, when the setting temperature point is rising to the set thermal alarm, start the over -limit alarm function.
When the controlled temperature cannot be effectively controlled, in order to prevent the destruction of the device, the device can be stopped to continue running by the door.It is mainly used in various high and low voltage switch cabinets, dry transformers, box -type substations and other related temperature use areas used by the power sector.
