In order to achieve application monitoring in explosive environments live or study in many parts of the industrial enterprises in petroleum, chemical, coal and scientific research,military,Explosion-proof cameras have come into being.
The current international mainstream way is flameproof explosion-proof cameras.
Wherein the conventional ordinary camera placed in a special housing that has the spark and arc shell casing outside electrical components produced an explosive mixture to isolate the effect, and can withstand the explosive mixture into the shell is the shell spark electrical equipment, explosion pressure generated by detonation of an arc, while the housing is not destroyed, the outer shell does not cause an explosive mixture of combustion and explosion.
This camera has a flameproof enclosure is the “Explosion-proof cameras,” and this special enclosure called “flameproof enclosure”, we usually call it “proof shield.”
That is, the explosion-proof camera that is “proof shield” + ordinary camera + lens. For Explosion-proof camera, it plays the role of the main Explosion-proof enclosure, just the right size, contractors can freely choose the built-in camera, lens, while also reducing costs. For future maintenance, but also facilitate a lot, opening the lid off the power to pull out the camera lens. This is also a large flameproof camera currently popular.
Explosion-proof enclosure can be a spark and arc with electrical components inside the shell of the body to produce an explosive mixture outside the isolated and can withstand the pressure of an explosive mixture into the shell explosion was shell detonated electrical sparks and arcs produced while preventing shell booster explosives inside to the outside world.
