Produced by Jinhu Dahua Automation Instrument Co., LtdExplosion proof thermistor (thermocouple)The explosion-proof performance of the product is designed and manufactured according to the national standard of "Explosion proof Electrical Equipment for Explosive Environments". The thermoelectric characteristics comply with the IEC standard and have been tested and qualified by the National Instrument Explosion proof Safety Supervision Station. The structure, principle, and assembly method of the explosion-proof thermistor (thermocouple) are basically the same. The main difference is that the explosion-proof product junction box (shell) 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 also meets the national explosion-proof standard. So when the explosive mixed gas inside the junction box explodes, its internal pressure will not damage the junction box, and the resulting heat energy cannot spread or explode outward. As long as users strictly follow the product usage rules, explosion-proof thermal resistance (thermocouple) products can achieve reliable explosion-proof effects.
