Principle of explosion-proof thermocouple
2011-12-6 8:55:41

的特点 Features of explosion-proof thermocouples

Wide temperature measurement range

High mechanical strength and good pressure resistance

Spring-loaded temperature sensor with good anti-vibration performance

Multiple explosion-proof forms, good explosion-proof performance

、热电阻作为温度测量和控制的传感器与显示仪表配套,以直接测量和控制生产过程中的气体、液体和蒸汽的温度。 Industrial explosion-proof thermocouples and thermal resistors 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.


,热电阻的结构、原理与装配方式基本相同,主要区别是隔爆产品接线盒(外壳)在设计上采用高强度铝合金压铸而成,并具有足够的内部空间,壁和 The structure, principle and assembly method of the flameproof thermocouple are basically the same. The main difference is that the flameproof product junction box (housing) is designed by die-casting high-strength aluminum alloy and has sufficient internal space.

The mechanical strength and the thermal stability of the rubber seal ring meet the national explosion-proof standards. Therefore, when the explosive mixed gas inside the junction box explodes, its internal pressure will not damage the junction box, and the resulting thermal energy cannot be diffused outwards-

-Passing. As long as the user strictly adheres to the product usage rules, the product can achieve a reliable explosion-proof effect.
