Explosion Proof

2009

What is the difference between explosion proof and intrinsically safe equipment?

Intrinsic Safety: This method of protection limits the power to pass into the danger zone. The limitation of energy is provided by the use of barriers security which are mounted in the safety zone. Due to the limitation of energy, regardless of fault in the danger zone, an energy may not be sufficient to ignite the released explosive atmosphere. Explosion-proof: It is the most popular method of protection. When an explosive gas between an enclosure containing electrical equipment of an explosion could occur. With the speaker properly installed and tight tolerance between housing and cover, the flame will cool enough when it reaches the outer atmosphere.
