Gas sensors are an important part of many industries. People rely on these tools to keep them safe.
It's easy to think that these sensors are all the same, but they're not. Some are more accurate than others. Some are safer than others. In terms of safety, explosion-proof sensor housings are an important part of the sensor design. Because the reality is that when you use gas sensors, you may be placing electrical equipment near hazardous gases. All it takes for these gases is a spark to start a fire—or worse—explode. Without an explosion-proof sensor housing, you could be in for disaster.
So how do explosion proof sensor enclosures work?
Explosion proof sensors allow explosions to occur inside electrical instruments, so they do not prevent ignition. However, the housing is designed and constructed to prevent explosions from escaping the instrument. Although an internal explosion occurs, it does not spread into the explosive atmosphere. These explosion proof enclosures can incorporate a number of different design elements to achieve their goals. HENGKO's gas sensor housing supports that they can choose the appropriate thickness to achieve detection on the housing wall, which meets the gap size and installation specifications.
These sensor housings do not protect against explosions, but they do prevent their spread into the atmosphere.

Explosion-proof sensor assemblies are made of 316 stainless steel for maximum corrosion protection. A sinter-bonded flame arrestor provides the gas diffusion path to the sensing elements while maintaining the flame-proof integrity of the assembly. Sensing elements are specially designed for maximum poison resistance and long life in harsh industrial environments, with sensor life typically 2 years or more.
