Explosion-proof fixed thread thermocouple
1. Explosion-proof fixed thread-type thermocouple - applications
Explosion-proof thermocouples are usually used in conjunction with display instruments, recorders, electronic computing, and similar devices. Directly measures the surface temperature of liquids, vapors, gases, and solids in the 0°C~1300°C range for explosives such as hydrocarbons at the production site.
2. Features of explosion-proof fixed threaded thermocouples
Multiple explosion-proof types, excellent explosion-proof performance, spring-type temperature sensing elements, excellent vibration resistance, wide temperature measurement range, high mechanical strength, and good pressure resistance
3. Explosion-Proof Fixed Thread Thermocouple - Working Principle
Explosion-proof thermocouples utilize the explosion-proof principle of gaps, designed with sufficiently strong junction boxes and other components. All components that may generate sparks, arcs, or hazardous temperatures are sealed inside the junction box chamber. When an explosion occurs inside the chamber, the flame can be extinguished and cooled through the gap at the joint surface, preventing the flame and temperature from passing outside the chamber, thus providing explosion protection.
