Explosion proof thermal resistance wzp-241 thermal resistance PT100 protection tube

The explosion-proof thermal resistance uses the principle of gap explosion-proof to design the junction box and other components with sufficient strength. All the components that will produce sparks, arc and dangerous temperature are sealed in the junction box cavity. When there is an explosion in the junction box cavity, it can extinguish and cool through the gap of the joint surface, so that the flame and temperature after explosion can not be transmitted outside the cavity, so as to measure the temperature.
