Rosemount 975HR Multi-spectrum Infrared Hydrogen Flame Detector Product Data Sheet Multi-spectrum Infrared Hydrogen Flame Detector The Rosemount 975HR Multi-spectrum Infrared Hydrogen Flame Detector is specifically designed for detection of hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and gas fires at long distances with the highest immunity to false alarms. The 975HR can detect a gasoline pan fire at 215 ft (65m) or a hydrogen flame at 125 ft (38 m) in less than 5 seconds. The Rosemount 975HR is the most durable and weather resistant flame detector on the market. Its features include a heated window to eliminate condensation and icing, HART®, lower power requirements and a compact lighter design. Features & Benefits ■ Multi spectrum design - for long distance detection of hydrocarbons and hydrogen flames ■ High false alarm immunity ■ Sensitivity selection - to ensure no zone crossover detection ■ Automatic and Manual Built-in-Test (BIT) - to assure continued reliable operation ■ Heated window - for operation in harsh weather conditions ■ Multiple output options for maximum flexibility and • Relays (3) for Alarm, Fault and Auxiliary • HART® Protocol for maintenance and asset ■ High Reliability - MTBF - minimum 150,000 hours ■ Approved to Safety Integrity Level 2 (SIL2 - TUV) ■ User Programmable via HART® or RS-485 Rosemount 975HR Multi-spectrum Infrared Hydrogen Flame Detector. ■ Oil & Gas - Offshore & Onshore process facilities ■ Storage Tank farms ■ Power Generation facilities ■ Waste Disposal facilities ■ Hydrogen Fuel Cell Industry ROSEMOUNT EMERSON.
