The principle and characteristics of explosion-proof thermocouple

The principle of explosion-proof thermocouple:

The structure and principle of explosion-proof thermocouples are basically the same as those of assembled thermocouples. The difference is that the explosion-proof product junction box (housing) is designed with high-strength aluminum alloy die-casting, and has sufficient internal space, wall thickness, and mechanical strength. The thermal stability of the rubber sealing ring meets national explosion-proof standards. So when the explosive gas mixture inside the junction box explodes, its internal pressure will not damage the junction box, and the resulting heat energy cannot diffuse outward - the explosion cannot be transmitted. As long as users strictly follow the product usage rules, the product can achieve reliable explosion-proof effect. Industrial explosion-proof thermocouples are widely used as temperature sensors in chemical industry automation systems.

Characteristics of explosion-proof thermocouple:

Multiple explosion-proof forms with 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; Adopting a two chamber explosion-proof structure, it is easy to replace temperature measuring elements, safe and reliable to use, and suitable for temperature measurement in explosive gas environments. Pressure spring type temperature sensing element with good anti vibration performance; High measurement accuracy; No need to compensate for wires, saving costs; Imported thin film resistor components with reliable and stable performance.
