IFD-E (IS) | Hochiki's EN Approved Fire Detection

Intrinsically Safe Industrial IR³ Infra-Red Flame Detector | Intrinsically Safe & Explosion Proof

IFD-E (IS) Description 


IFD-E (IS) is an Intrinsically Safe IR³ flame detector designed for use where open flaming fires may be expected and responds to the light emitted from flames during combustion. The detector discriminates between flames and other light sources by responding only to particular optical wavelengths and flame flicker frequencies.


This enables the detector to avoid false alarms due to such factors as flickering sunlight. Ideal for the detection of flames from the burning of Aviation Fuels (kerosene), Butane, Grain & Feeds, Hydrogen, Paper, Natural Gas, Petrol (gasoline) etc.
