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

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MAR

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MAR

Apollo Marine Intelligent Base Mounted UV Flame Detector 55000-027MARThe Marine Intelligent Base Mounted UV Flame Detector is designed to protect enclosed indoor areas where open fires may be expected. The detector has a fast-acting response to flames up to 25m away and is equipped with a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation.ApplicationUV flame detectors are used when detection is required to be unaffected by convection currents draughts or wind. These include engine rooms in ships factories affected by draughts or wind and warehouses. They are fast reacting and respond to a flame more than 25m away. The UV flame detector is affected by arc welding electrical sparks lightning nuclear radiation and UV light sources. For applications where these phenomena are present a UV flame detector should not be used.OperationThe detector is sensitive to ultraviolet radiation emitted by flames during combustion. Since it requires only UV radiation the detector responds even to stationary flames with no flicker like cigarette lighters and blue gas flames.The detector is set to respond to ultraviolet radiation 185260nm emitted by almost all flames including those invisible to the naked eye e.g. hydrogen fires. The detector has a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation and is designed for internal fully enclosed areas. Caution The detector will also detect electrical discharges from lightning or arc welding.Key FeaturesResponds to stationary flames with no flickerSensitive to UV radiation emitted by flames during combustionCompact flame detector which fits into Discovery Marine baseLoop-powered

Apollo Marine Intelligent Base Mounted IR3 Flame Detector 55000-029MAR

Apollo Marine Intelligent Base Mounted IR3 Flame Detector 55000-029MAR

Apollo Marine Intelligent Base Mounted IR3 Flame Detector 55000-029MARThe Intelligent Base Mounted IR3 Flame Detector is designed to protect all indoor areas even in dirty or smoky conditions where open flaming fires may be expected. The detector has three IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation.ApplicationThe triple IR flame detector is also fast reacting but is also tolerant of fumes vapours steam dust and mist while being unaffected by the phenomena listed above. It may however be affected by modulated IR radiation. Triple IR flame detectors are used in waste handling colour printing and paper manufacturing.OperationThe detector is sensitive to low-frequency flickering infra-red radiation emitted by flames during combustion. Since it responds to flickering radiation the detector can operate even if the lens is contaminated by a layer of oil dust water-vapour or ice. The detector is set to respond to low-frequency radiation at 1-15Hz 0.75-2.7ym in order to detect all flickering flames including those invisible to the naked eye e.g. those emitted by hydrogen fires.The detector has three IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms due to factors such as flickering sunlight are avoided by a combination of filters and signal processing techniques.Key FeaturesResponds to stationary flames with no flickerSensitive to low-frequency flickering IR radiation emitted by flames during combustionCompact flame detector which fits into Discovery Marine mounting basesLoop-poweredFalse alarms due to factors such as flickering sunlight are avoided by a combination of filters and signal processing techniques
