The difference between flameproof thermocouples and ordinary thermocouples
2011-12-26 9:59:38

和普通热电偶的结构基本相同,其区别在于:隔爆型产品的接线盒在设计上采用特殊防爆结构,接线盒用高强度铝合金压铸而成,并且有足够的内部空间,壁厚和机械强度, The structure of explosion-proof thermocouples and ordinary thermocouples is basically the same. The difference is that the junction box of explosion-proof products is designed with a special explosion-proof structure. Wall thickness and mechanical strength,

The thermal stability of the rubber seals meets national explosion-proof standards. Therefore, when the explosive mixed gas inside the Qin junction box explodes, its internal pressure will also damage the junction box, and the heat generated by it cannot be diffused outward. Explosion-proof thermocouples have explosion-proof function.

通常使用在会产生火花、电弧和高温危险的生产现场,这类现场存在大量的碳氢化合物等爆炸物,防爆热电偶通过将会产生火花、电弧、和高温的零部件密封在高强度的接线盒腔内。 Explosion-proof thermocouples are usually used in production sites where sparks, arcs, and high-temperature dangers occur. There are a lot of explosives such as hydrocarbons on such sites. The strength of the junction box cavity.

Utilizing the principle of gap explosion isolation, when an explosion occurs in the cavity, the flame is extinguished and cooled through the gap of the joint surface, so that the flame and temperature after the explosion cannot be transmitted outside the cavity, thereby performing explosion isolation. Explosion-proof thermocouples are often used together with display instruments, recording instruments, and electronic meters.

特点 Flameproof Thermocouple Features


Designed according to the latest explosion-proof regulations GB3836 in compliance with international IEC standards


Adopt two-chamber flameproof structure, easy to replace temperature measuring element, safe and reliable to use

Explosion-proof mark dⅡCT6, suitable for temperature measurement below IIC level, ignition temperature above T6, and in the presence of explosive gas.
