Explosion-proof thermal resistance is usually used in conjunction with display instruments, recording instruments, electronic calculations, etc. Directly measure the surface temperature of liquid, vapor and gaseous media and solids in the range of -200°C~500°C where hydrocarbons and other explosives exist at the production site.
Features of explosion-proof thermal resistance
Compression spring type temperature sensing element, good anti-vibration performance;
High measurement accuracy;
No need to compensate the wire, saving cost;
Imported thin film resistor elements, reliable and stable performance.
Working principle of explosion-proof thermal resistance
It uses the principle of gap explosion isolation to design junction boxes and other components with sufficient strength. All parts that generate sparks, arcs and dangerous temperatures are sealed in the junction box cavity. When an explosion occurs in the cavity, it can pass through the gap of the joint surface. Extinguish and cooling, so that the flame and temperature after the explosion can not pass to the outside of the cavity, so as to isolate the explosion.
