Electric Heat Tracing Product Features
Principle
After power is turned on (note: the end core wires must not be connected), current flows from one core wire through the conductive PTC material to the other core wire, forming a circuit. The electrical energy heats the conductive material, causing its resistance to increase. When the temperature of the core tape rises to a certain value, the resistance becomes so large that it almost blocks the current, and the temperature no longer rises. At the same time, the electric heat tracing transfers heat to the heated system with a lower temperature.The power of the electric heat tracing is mainly controlled by the heat transfer process, automatically adjusting the output power according to the temperature of the heated system, while traditional constant power heaters do not have this function
