WRN2-240 Explosion Proof thermocouple


WRN2-240 Explosion Proof thermocouple is usually used with display instrument, recording instrument, electronic computer, etc. It is often used to directly measure the surface temperature of liquid, steam, gas medium and solid in the range of 0 ℃ ~ 1300C when there are explosives such as hydrocarbons in the production site.

Working principle

WRN2-240 Explosion Proof thermocouple uses the principle of gap explosion-proof to design the junction box and other components with sufficient strength. 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.


Good explosion-proof performance and various explosion-proof forms

Temperature sensing element is spring loaded, with good vibration resistance

The temperature range is large
