Gas detectors are common explosion-proof products, including intrinsic safety, explosion-proof, and both explosion-proof and intrinsic safety types. The choice of explosion-proof type depends on the structure, electrical parameters, installation method, and usage location of the product.

It is recommended to obtain an intrinsic safety explosion-proof certificate for portable and handheld devices, as they are relatively lightweight. In addition, if it is a gas detector used in Zone 0, it can only be used for intrinsically safe IA explosion-proof level. When doing intrinsic safety type, consideration should be given to the intrinsic safety design of the circuit, the material of the casing, battery temperature rise testing, etc.

Fixed ones can be considered as explosion-proof. Explosion proof products are relatively bulky, mainly achieved through explosion-proof enclosures. Even if sparks are generated by internal components, the explosion-proof shell can block the propagation of explosions. On the other hand, the shell can also prevent external explosion sparks from entering the interior of the equipment.

Of course, there are also some gas detectors that cannot achieve explosion-proof performance simply by intrinsic safety or explosion-proof. In this case, it is necessary to consider composite explosion-proof types such as explosion-proof and intrinsic safety.

Zhongnuo TestingAt present, we have obtained domestic and international explosion-proof certificates for gas detectors, alarms, transmitters and other instruments for our customers. We have rich experience and cases in evidence collection. Welcome to communicate with us by private message!
