1. Application of Explosion proof Thermocouples

Usually used in conjunction with display instruments, recording instruments, electronic computing, etc. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of 0 ° C to 1300 ° C in the presence of hydrocarbons and other explosives on the production site.

2. Characteristics of Explosion proof Thermocouples

·Multiple explosion-proof forms with good explosion-proof performance;

·Pressure spring type temperature sensing element with good anti vibration performance;

·Large temperature measurement range;

·High mechanical strength and good pressure resistance;

3. Working principle of explosion-proof thermocouple

Explosion proof thermocouple utilizes the principle of gap explosion-proof to design junction boxes and other components with sufficient strength. All components that can generate sparks, arcs, and dangerous temperatures are sealed inside the junction box cavity. When an explosion occurs inside the cavity, it can be extinguished and cooled through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the cavity, thus achieving explosion-proof.
