20/20L-LB UV/IR Flame Detector The SharpEye UV/IR Optical Flame Detectors 20/20L and 20/20LB (which includes a BIT function) are an improved version of the well-proven Spectrex Ultra Violet/Infra Red (UV/IR) optical flame detectors featuring modern microprocessors and detection algorithms that provide excellent detection sensitivity combined with enhanced immunity to false alarms. These enhanced models were developed in light of our highly successful experience in high-speed flame detection technology for both military and commercial industrial applications. Both models are designed to detect hydrocarbonbased fuel fires, hydroxy and hydrogen fires as well as metal and inorganic fires. The UV/IR flame detector senses energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The sensor band pass has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire, and the lowest degree of matching to non-fire stimuli. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. The IR sensor is sensitive to radiation over the range of 2.5 to 3.0 microns. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous matching of radiant energy in both the UV and IR sensors triggers an alarm signal.
