WRN-240 WRN2-240 WRN-440 WRN2-440 Explosion proof thermocouple

Working principle

WRN-240 WRN2-240 WRN-440 WRN2-440 Explosion proof thermocouple, Seal all parts that can produce sparks, arcs and dangerous temperatures in the junction box. When explosion occurs in the cavity, it can be flamed out and cooled through the gap of the joint surface, so that the flame and temperature after explosion cannot be transmitted outside the cavity, so as to conduct explosion-proof.uses the principle of gap explosion-proof to design the junction box and other components with sufficient strength.
