Principle, scope of application, and selection of self limiting temperature electric heating belt
The self limiting temperature (self limiting) electric heating belt is composed of a conductive polymer, two parallel metal wires, and an insulating protective layer. Its characteristic is that the conductive polymer has a high positive temperature coefficient PTC characteristic and is connected in parallel. It can automatically adjust the output power according to the temperature changes of the heated system, and automatically limit the heating temperature. It can be shortened arbitrarily or extended within a certain range for use, and allows multiple cross overlaps without concerns of high temperature hotspots or burning. Therefore, the above-mentioned strip heating belt is suitable for the heated system, while the traditional constant power heater affects the heated system. Therefore, the self limiting temperature electric heating belt has the following advantages:
1. The electric heating belt is equipped with a corresponding heat tracing system, which automatically adjusts the output power and will not burn out due to its own heating. However, it compensates for the actual need for heat, making it a new generation of energy-saving type and the only strip heater.
2. Low temperature quick start, uniform temperature, all or part of it can be automatically adjusted due to temperature changes at the heat tracing location.
3. Easy to install and maintain, with a high level of automation. Our company's products have completely replaced similar imported products, with low operating and maintenance costs.
4. Safe and reliable, suitable for hazardous environments, widely used for antifreeze and insulation of process pipelines or containers and storage tanks, suitable for ordinary areas, hazardous areas, and corrosive areas, does not pollute the environment, and has a long service life.
