[0002] The working principle of the heating pipe dry burning prevention device is mainly based on temperature sensing and control technology. The device usually contains one or more temperature sensing elements, which can monitor the temperature of the heating pipe in real time. When the water level in the heating pipe is too low or completely without water, the temperature of the heating pipe will rise rapidly. Once the temperature reaches the preset threshold, the temperature sensing element will immediately send a signal to trigger the control circuit to cut off the power supply of the heating pipe, thereby stopping heating and preventing dry burning.

When dry burning occurs, the temperature of the heating pipe is transmitted to the thermal overload protection element through the air. The transmission temperature is not sensitive enough, and the circuit cannot be disconnected in time, which may cause the heating pipe to continue dry burning and damage the heating pipe. Most heating pipes are sealed with sealant. If power is not turned off in time during dry burning, the sealant will melt over a long period of time, causing the heating pipe to tilt.
