SharpEye 20/20U (UB)-1

20/20U-UB UV Flame Detector The SharpEye UV Optical Flame Detectors 20/20U and 20/20UB (which includes a BIT function) are designed to meet the strict industry performance requirements. The UV sensor has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire. Flame is detected typically within 3 sec. for a 1ft.2. (0.1m2) pan gasoline fire. A unique Fast UV Flame Detector Model (20/20FU) detects within several milliseconds a saturated UV signal caused by an explosion or a large fire. The microprocessor design allows for unique field programmability making these flame detectors easily adaptable to all environments, applications and requirements. systems or automatic fire extinguishing systems. The SharpEye UV Flame Detector incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. The UV detectors are particularly useful for detection of invisible flames from fuels such as: Hydrogen, Hydrides, Ammonia, Silane and other inorganic fuels. Both U and UB models are self-contained, optical flame detectors that function as stand-alone units directly connected to external devices such as alarm * It is important to note that this detector must not be exposed to UV radiation sources such as: electrical arcs, sparks and welding, etc. Main Features • UV Spectrum Design • Typical 3 second Response • User Programmable Configuration • Automatic and Manual Built-In Test (BIT) - UB • Standard 4-wire Connection • 4-20mA source (3-4 wires) configuration • MTBF Minimum 100,000 Hours • 3-Year Warranty • FM, CSA, ATEX and Gost K Approved Applications • Aerospace Industry - Hydroxy, Hydrogen and Hydrazine fuels • Automotive - manufacturing, paint spray booths • Chemical Industry - production, storage, transportation • Explosives & Munitions - handling and storage • Paint - manufacturing facilities • Petrochemicals - production, storage, shipping facilities • Pharmaceutical Industry • Polymers, Solvents and Glue - manufacturing and curing • Power Generation Facilities - pump areas, generator rooms, unmanned stations, gas-fired and coal-fired reactors • Printing Industry - solvent handling, presses, drying processes • Warehouses - storage facilities for flammable materials 218 Little Falls Road | Cedar Grove | NJ 07009 | USA Tel: +1 (973) 239-8398 | 1 (800) 452-2107 (Toll free US only) | Fax: +1 (973) 239-7614 E-mail: [email protected] | Web-site: www.spectrex-inc.com
