Explosion proof thermocouple with pipe connector

Overview of Explosion proof thermocouple with pipe connector

Explosion proof thermocouple with pipe connector are used as temperature measurement and control sensors and display instruments to directly measure and control the temperature of gas, liquid and steam in the production process. The explosion-proof performance of explosion-proof thermocouples and thermal resistors for chemical industry produced by our factory is designed and manufactured according to the standard of "explosion-proof electrical equipment for sexual environment" issued by the state. The thermoelectric characteristics meet the international IEC standards and pass the test of the national instrument explosion-proof safety supervision station The structure, principle and assembly method of flameproof thermocouple and thermal resistance are basically the same. The main difference is that the junction box (shell) of flameproof products is designed It is made of high-strength aluminum alloy die-casting, and has sufficient internal space, wall thickness and mechanical strength. The thermal stability of rubber seal diagram meets the national explosion-proof standard. Therefore, when the mixed gas inside the junction box occurs, its internal pressure will not damage the junction box, and the resulting heat energy cannot diffuse outward - explosion propagation. As long as users strictly abide by the product use rules, the product can achieve reliable explosion-proof effect.

Characteristic of Explosion proof thermocouple with pipe connector
Various explosion-proof forms, good explosion-proof performance;
Pressure spring type temperature sensing element with good anti vibration performance;
Large temperature measurement range:
High mechanical strength and good pressure resistance;
Working principle of Explosion proof thermocouple with pipe connector
The explosion-proof thermocouple uses the principle of gap explosion-proof to design the junction box and other components with sufficient strength to seal all parts that will produce sparks, arcs and dangerous temperatures in the junction box cavity. When it occurs in the cavity, it can extinguish and cool through the gap of the joint surface, so that the flame and temperature can not be transmitted outside the cavity, so as to carry out explosion-proof.
