工作原理

Operating   principles

防爆热电偶利用间隙隔爆原理,设计具有足够强度的接线盒等部件,将所有会产生火花、电弧和危险温度的零部件都密封在接线盒腔内,当腔内发生爆炸时,能通过接合面间隙熄火和冷却,使爆炸后的火焰和温度传不到腔外,从而进行测温。
Explosion-proof thermocouple uses the gap explosion proof principle to design the junction box and other components with enough strength to seal all the components that will produce sparks, arcs and dangerous temperatures in the junction box cavity. When an explosion occurs in the intracavity, it can achieve extinguishing and cooling the surface gap, so that the flame and temperature after the explosion can not pass outside the cavity, so as to measure temperature.
