Design according to the latest explosion-proof regulations GB3838 that comply with international IEC standards; Adopting a two chamber explosion-proof structure, it is easy to replace temperature measuring components, and uses the safe and reliable explosion-proof symbol d Ⅱ CT6. It is suitable for temperature measurement in situations below IIC level, ignition temperature T6 or above, and containing explosive gases.
Seal all components that can generate sparks, arcs, and hazardous temperatures inside the junction box. When an explosion occurs inside the box, it can be extinguished and cooled through the gap between the joint surfaces, preventing the flame and temperature from being transmitted outside the box.
Overview of Explosion proof Thermocouples: Industrial explosion-proof thermal resistors are used as sensors and display instruments for temperature measurement and control, to directly measure and control the temperature of gases, liquids, and vapors in the production process.
If a closed circuit is composed of two homogeneous conductors (thermoelectric electrodes) with different compositions, and there is a temperature gradient at both ends of the explosion-proof thermocouple, there will be current passing through the circuit. Therefore, there is a thermoelectric potential between the two ends of the explosion-proof thermocouple. The principle of gap explosion-proof is used to prevent explosion
