Explosion-Proof Point Type Smoke Fire Detector – Hazardous Area Certified Flame Detection

Explosion-proof smoke detector certified for hazardous locations, providing reliable flame and smoke sensing in oil, gas, and chemical plants.

Introduction of Explosion-proof point type smoke fire detector

XDT-Y-01 explosion-proof point type smoke fire detector, non-code switch type (relay output) detector. Detector adopts infrared scattering principle to detect fire, the circuit is mainly composed of infrared emitting part and receiving part, the transmitting tube and receiving tube are placed in the optical dark room, the optical dark room can shield the interference of external stray light, but does not affect the smoke into. In the smoke-free state, only receive very weak infrared light, when there is smoke into, due to the scattering effect, so that the received light signal is enhanced, when the smoke reaches a certain concentration, can output alarm signal.

Procurement Recommendation

Explosion-proof smoke detectors for hazardous areas must carry ATEX/IECEx Zone 1 or NEC Class I Div 1 certification. Never substitute standard detectors in flammable vapor environments; perform regular bump tests with certified aerosols. (for reference only)
