Overview of Flameproof Thermocouples
2011-12-24 10:12:55

是一种温度传感器,在化学工业自控系统中应用极广,通过温度传感器, 可将控制对象的温度参数变成电信号,传递给显示、记录和调节仪,对系统施行检测、调节和控制。 Industrial explosion-proof thermocouple is a kind of temperature sensor. It is widely used in the chemical industry automatic control system. Through the temperature sensor, the temperature parameter of the control object can be converted into an electric signal, which is transmitted to the display, record and adjuster to implement the system. Detection, regulation and control.


The structure, principle and assembly method of flameproof thermocouple and thermal resistance 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. Mechanical strength of rubber seals

Thermal stability meets national explosion-proof standards. Therefore, when the explosive mixed gas inside the junction box explodes, the pressure within the period will not damage the junction box, and the thermal energy generated by it will not be able to diffuse outward-transfer explosion. As long as the user strictly adheres to the product usage rules, the product can reach

Reliable explosion protection


特点: Flameproof thermocouple features:


Multiple explosion-proof types, good explosion-proof performance


Compressed spring-type temperature-sensitive original, good vibration resistance


Wide temperature measurement range


High mechanical strength and good pressure resistance

工作原理: Flameproof thermocouple working principle:


The fireproof thermocouple is based on the principle of gap explosion protection, designed with sufficient strength of the junction box and other components, all parts that will produce sparks, arcs and dangerous temperatures are sealed in the junction box cavity. When an explosion occurs in the cavity, it can pass through Quenching and cooling of joint gaps,

The flame and temperature after the explosion can not be transmitted outside the cavity, so that the explosion is isolated
