Fuji transmitter flameproof and intrinsically safe explosion-proof difference
In the industrial scene often need to use the explosion-proof function of the pressure instrument, and the general industrial explosion-proof instrument is mainly explosion-proof and flameproof type.
Explosion-proof type is generally used in flammable and explosive environment, such as coal mine, gas station and other fields, divided into flameproof type and intrinsically safe explosion-proof two, the function is similar, but essentially different explosion-proof type.
Flameproof explosion-proof technology is on the structure, isolated from the rest of the circuit and the surrounding environment with isolation measures, make the heat generated by the circuit in the normal work and electric spark and high temperature in fault state, are restricted within the shell of seal, in order to prevent the surrounding flammable and explosive gas ignition, popular point, is the product with a layer of explosion-proof box, Keep gases or sparks that could cause an explosion in the environment out of the air.
Intrinsic safety technology is generally used in the instrument, by limiting the energy in the electrical circuit and with the structural design of electrical equipment, so that in normal and accident conditions, the possible electric spark or thermal effect is smaller than the minimum ignition energy and spontaneous combustion temperature of explosive dangerous gas.
Petroleum, chemical, coal and many other industrial sectors, in the production, processing, transportation and storage of various processes, often may leak or spill out a variety of flammable and explosive gas, liquid and dust and fiber. After mixing with air, this kind of substance may become a mixture with the risk of explosion. When the concentration of the mixture reaches the range of explosion concentration, once there is an ignition source, it will cause serious accidents such as explosion and fire. All instruments and instruments used in such dangerous environments must be certified by professional institutions with explosion-proof properties.
Fuji explosion-proof pressure transmitter, with intrinsically safe explosion-proof ExiaⅡCT6 Ga and flameproof ExdⅡCT6 Gb double certificate, intrinsically safe, compact volume, convenient installation, can run smoothly in the environment of explosive gas mixture, to solve customers' worries.
