Principle of explosion-proof electric heating tube

- Aug 22, 2019-

Usually used with display instruments, recording instruments, electronic calculations, etc. Direct measurement of liquid, vapor and gaseous media and solid surface temperatures in the range of 0 °C to 1300 °C for explosives such as hydrocarbons at the production site.


2, Features · A variety of explosion-proof forms, good explosion-proof performance; · Pressure spring type temperature sensing components, good anti-vibration performance; · Large temperature range; · High mechanical strength, good pressure resistance;


3, working principle Explosion-proof thermocouple is to use the gap explosion-proof principle, design a junction box and other components with sufficient strength, all the parts that will generate sparks, arc and dangerous temperature are sealed in the junction box cavity, when the cavity explosion When the joint surface is extinguished and cooled, the flame and temperature after the explosion are not transmitted outside the cavity, thereby performing explosion-proof.
