Intrinsic safety and explosion-proof

These are two different types of explosion-proof protection

Explosion proof is generally protected by an explosion-proof shell,Explosion proofThe shell should have sufficient thickness and strength, so that even if an explosion occurs inside the equipment, the flame will extinguish due to the width, gap, and roughness of the explosion-proof shell joint surface, and will not ignite the external hazardous environment; On the other hand, even in the event of an explosion in a hazardous location outside, the explosion-proof enclosure still has blast resistance.

Overall, the shell is both blast resistant and blast resistant. The equipment will be relatively bulky.

Intrinsic safetyEssentially safe, the equipment achieves intrinsic safety by limiting circuit energy, etc. Intrinsic safety products have relatively high requirements for the circuit and working power of the equipment, and are generally suitable for handheld devices, low-power products, etc.
