?? The industrial used explosion-proof thermal resistance takes the temperature survey and the control sensor and the display instrument necessary, by direct measurement and in control production process gas, liquid and steam temperature.
??? Our company produces the chemical special-purpose explosion-proof thermo-element, the explosion-proof thermal resistance product explosion-proof performance according to the national promulgation “the explosive environment with the permissible electrical equipment” the modular design manufacture, the thermoelectricity characteristic conforms to the international IEC standard, and is qualified after the country instruments and meters explosion-proof safety surveillance station test. The explosion-proof thermo-element, the explosion-proof thermal resistance's structure, the principle and the assembly way basic same, the main difference is the flame-proof product connecting box (outer covering) uses the high strength aluminum alloy compression casting in the design to become, and has the enough inner space, wall thickness and the mechanical strength, the rubber seal packing collar's thermostability conforms to the national explosion-proof standard. When therefore the connecting box internal explosivity gaseous mixture has the detonation, its intrinsic pressure will not destroy the connecting box, but produces from the heat energy cannot the outward diffusion--Detonation. So long as the user observes the product use rule strictly, the explosion-proof thermal resistance product can achieve the reliable explosion-proof effect.
