Rosemount 975UR Ultraviolet Infrared Flame Detector FGD-PDS-975UR-Ultraviolet-Infrared-Flame-Detector Product Data Sheet March 2016 Ultraviolet Infrared Flame Detector Rosemount 975UR provides a combination of UV and IR sensors, where the IR sensor operates at a wavelength of 4.5 μm, and can detect hydrocarbon-based fuel and gas fires. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. 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. Rosemount 975UR Ultraviolet Infrared Flame Detector. Features & Benefits UV/IR Dual-Sensor Automatic and Manual 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 • 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 (SIL2 – TÜV) 5-Year Warranty User Programmable via HART® or RS-485 Oil & Gas - Offshore & Onshore process facilities Chemical plants Petrochemicals plants Storage Tank farms Aircraft hangars Power Generation facilities Pharmaceutical Industry Printing Industry Warehouses Waste Disposal facilities Aerospace Industry Paint, Polymer and G
