Apollo Marine Intelligent Base Mounted UVIR2 Flame Detector 55000-028MAR

Apollo Marine Intelligent Base Mounted UVIR2 Flame Detector 55000-028MARThe Marine Intelligent Base Mounted UV Dual IR Flame Detector is designed to protect open indoor areas where open flaming fires may be expected. The detector has a UV and dual IR sensors responding to different wavelengths in order to discriminate between flames and spurious sources of radiation. They are used in aircraft hangers generator rooms diesel and gas turbines and paint works.OperationThe detector is sensitive to ultraviolet and low-frequency flickering infra-red radiation emitted by flames during combustion. Since it requires both UV and IR radiation the detector can operate in applications where a basic single UV or single IR detector would be inappropriate. The detector is set to respond to ultraviolet 185 - 260nm and low-frequency flickering infra-red 0.75 - 2.7ym radiation at 1 - 15Hz in order to detect all flickering flames including those invisible to the naked eye e.g. those emitted by hydrogen fires.The detector has one UV and two IR sensors responding to different wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms due to electrical discharges from lightning or arc welding and flickering sunlight are minimised by combining the UVIR signals.Key FeaturesResponds to stationary flames with no flickerSensitive to low-frequency flickering IR radiation emitted by flames during combustion.Compact flame detector which fits into Discovery Marine basesLoop-poweredFalse alarms due to factors such as flickering sunlight are avoided by a combination of filters and signal processing techniques
