Rosemount 975UF Ultra Fast Ultraviolet Infrared Flame Detector FGD-PDS-975UF-Ultra-Fast-Ultraviolet-Infrared-Flame-Detector Product Data Sheet March 2016 Ultra Fast Ultraviolet Infrared Flame Detector The Rosemount 975 ultra fast ultraviolet infrared flame detector is designed to meet two major requirements: High-Speed Response (20 msec) High Reliability (immunity to false alarm) The Rosemount 975UF ultra fast ultraviolet infrared flame detector can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires. The UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Rosemount 975UF Ultra Fast Ultraviolet Infrared Flame Detector. Features & Benefits Applications (model dependent) UV/IR dual-sensor High-speed response - 20 msec to flash fire Solar blind Automatic Built-In-Test (BIT) - to assure continued reliable operation Heated window - for operation in harsh weather conditions (snow, ice, condensation) Multiple output options for maximum flexibility and compatibility • Relays (3) for alarm, fault, and auxiliary • Analog output for fast detection • 0–20 mA (stepped) • HART® Protocol for maintenance and asset management • RS 485, Modbus compatible High reliability - MTBF - minimum 150,000 hours Approved to Safety Integrity Level 2 (SIL 2 - TÜV) 5 year warranty User programmable via HART® or RS-485 Explosives and Ammunition Offshore Oil & Gas Onshore Oil & Gas Petrochemical plants Storage tank farms Aircraft hangars Chemical plants Power generation facilities Pharmaceutical industry Printing industry Warehouses Automotive industry Waste disposal facilities Aerospace industry Hydrogen Fuel Cell industry Hydrogen Vehicle Parking & Refueling Battery Charging Areas Refinery Hydrogenation Space Industry Hydroxyl Propellant Static F
