Brand : TECHTONGDA
BulletPoint : Replacement For HH18HA416 Furnace Temperature Limit Switch Compatible for with 314679, 95314679 - SRE1-1-957
BulletPoint1 : 【Intelligent Temperature Control System】: It adopts high-precision B-type thermocouples in combination with high-quality heating elements to achieve a temperature control accuracy of ±1℃, with a maximum operating temperature of up to 1700℃. The intelligent PID control system supports a linear heating rate of 0-20℃/min, meeting the strict requirements for temperature curves in ceramic sintering, metallurgy and other processes
BulletPoint2 : 【Gas Control System】: The vacuum level in the furnace chamber can be monitored in real time through a vacuum pressure gauge. It integrates a float-type flowmeter, allowing for intuitive adjustment of gas flow. The inlet and outlet valves support the switching of multiple gases, ensuring safe gas exchange under high-temperature working conditions
BulletPoint3 : 【High Efficiency Energy-saving Structure Design】: The lightweight alumina polycrystalline fiber furnace chamber features excellent heat insulation, high-temperature resistance, and rapid thermal cycling capabilities. Combined with double-layer thickened steel plate furnace doors, it effectively blocks heat transfer, achieving maximum thermal efficiency and saving 60% to 80% of energy
BulletPoint4 : 【Safety Protection Configuration】: The electric furnace adopts modular control with integrated circuits and dual-circuit protection (including over-temperature protection, over-temperature protection, open circuit protection, etc.), ensuring stable and safe operation. Heavy-duty double-layer structure, with built-in cooling fans and thickened steel plate furnace doors, ensures that the inner and outer surface temperatures remain within a safe range during operation
BulletPoint5 : 【Multi-functional Control Panel】: The panel integrates functions such as temperature controller, ammeter, voltmeter, on/off, power indicator light, and open circuit indicator light. It features an intelligent LCD display that clearly shows data and is easy to operate
