Application
It is usually used with display instruments, recording instruments and computers to directly measure the surface temperature ranging from -200°C~500°C of liquid, steam and gas medium and solid containing hydrocarbons and other explosives on various production sites.
Product features
Pressure spring type temperature-sensing element, good vibration resistance; no need for compensation lead, saving cost; high measuring accuracy; imported membrane resistance component, reliable and stable performance.
Working principle
The explosion-proof thermocouple uses the gap flameproof principle. It is designed with such components as junction box that has sufficient strength, sealing all parts subject to the generation of spark, electric arc and dangerous temperature in the junction box. When explosion occurs in the box, the gap between joint faces can extinguish the flame and cool down, so the flame and temperature after explosion will not move out of the box.
Product standards
IEC751, JB/T8622-1997, JB/T8623-1997, JB/T5518-1991, GB3836
Room temperature insulation resistance
When the ambient temperature of the explosion-proof thermal resistance is 15~35°C, the relative humidity is not greater than 80%, and the test voltage is 10~100V(DC), the insulation resistance between the electrode and the outer sleeve≥1000MΩ.m.
Categories of electrical equipment
Category I ------- electrical equipment for underground coal mine use
Category II ------- electrical equipment for factory use
Explosion-proof grade
The explosion-proof grades of explosion-proof thermocouple can be classified into three grades of A, B and C as per the maximum experimental safe gap for explosive gas mixture.
