1. Explosion-proof thermocouple application
Usually it is used with display instrument, recording instrument, electronic calculation and so on. The temperature of liquid, vapor and gas media and solid surface in the range of 0 C ~ 1300 C where hydrocarbons and other explosives exist in the production site are measured directly.
2. Characteristic of Explosion-proof Thermocouple
· A variety of explosion-proof forms, explosion-proof performance is good;
· Pressure spring type temperature sensor has good anti-vibration performance.
· The range of temperature measurement is wide.
· High mechanical strength, good pressure resistance;
3. Working Principle of Explosion-proof Thermocouple
Explosion-proof thermocouple is based on the principle of gap flameproof. It designs junction boxes with enough strength to seal all components that will generate sparks, arcs and dangerous temperatures in the junction box. When explosion occurs in the cavity, it can extinguish and cool through the gap of the junction surface, so that the flame and temperature after explosion can not pass out of the cavity, so that explosion-proof can be carried out.
4. Main technical parameters of explosion-proof thermocouple
Product Execution Standards
5. Insulation Resistance of Explosion-proof Thermocouple at Room Temperature
The insulation resistance of the thermocouple between the 500+50V (DC) electrode and the outer bushing is more than 1000_.m. The relative humidity of the thermocouple is not more than 80% and the ambient temperature is 20+15 degree C.
