Temperature controller refers to a series of automatic control elements, which have physical deformation inside the switch according to the temperature change of the working environment, so as to produce some special effects, and produce on or off action. It is also called temperature control switch, temperature protector and temperature controller, referred to as temperature controller. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends the switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect.

Temperature controller is widely used in many products, such as household appliances, motors, refrigeration or heating, etc.



Its working principle is that the ambient temperature is automatically sampled and monitored by the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit starts and the control return difference can be set. If the temperature is still rising, when the temperature rises to the set temperature point, the overrun alarm function will be started. When the controlled temperature can not be effectively controlled, in order to prevent the damage of the equipment, the device can be stopped by tripping function. It is mainly used in all kinds of high and low voltage switchgear, dry-type transformer, box type substation and other related temperature application fields.
