The XP95 Dual IR Flame Detector is sensitive to low-frequency, flickering infra-red radiation emitted by flames during combustion. Since it responds to fl ickering radiation the XP95 Dual IR Flame Detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour or ice.
The XP95 Dual IR Flame Detector is set to respond to low-frequency radiation at 1 to 15Hz (1 to 2.7µm) in order to detect all fl ickering fl ames, including those invisible to the naked eye, eg, those emitted by hydrogen fires.
The XP95 Dual IR Flame Detector has two IR sensors that respond to different IR wavelengths in order to discriminate between fl ames and spurious sources of radiation. False alarms due to such factors as fl ickering sunlight are avoided by a combination of fi lters and signal processing techniques.
