Introduction to self-limiting low temperature tracking zone

Self-limiting temperature zone is also called self-controlled electric tracing zone or self-controlled temperature zone. This is the annular temperature limiting heater whose output power is adjusted with the temperature of the system software. That is to say, the electric heating belt itself has the characteristics of automatic temperature limit, which can automatically adjust the heating power according to the temperature change of the heating system, so as to ensure the normal operation of the working system within the set working temperature range. The automatic thermoelectric belt can also be shortened or lengthened within the required range. It has the advantages of excellent dielectric strength, aging resistance, bottom pressure operation, trustworthiness, good flexibility, convenient installation, application and maintenance.

Self-limiting low temperature with tropical characteristics

PTC effect, power self-regulation. The electric heating element of the automatic temperature control electric heating belt is a core strip made of PTC semiconductor heating material squeezed between two parallel wires. When the PTC core is energized, its resistance will automatically increase. When the temperature rises to a certain value, the resistance is large enough to almost block the current, and the PTC core temperature no longer rises. At the same time, the PTC core belt transfers heat to the heated body through the sheath, and the temperature drops. At this time, the resistance of the core band gradually decreases, and the heating temperature of the core band rises again. This cycle can keep the temperature of the heating system constant, thus exerting its excellent performance.
