Rosemount 975MR Multi-spectrum Infrared Flame Detector Product Data Sheet Multi-spectrum Infrared Flame Detector The Rosemount 975MR multi-spectrum infrared flame detector is based on accurately analyzing the multi-spectral signals by three separate IR sensors. The 975MR detects fuel and gas fires at long distances. For example, this product will detect a 1 ft2 (0.1 m2) gasoline pan fire at 215 ft (65 m) in less than 5 seconds. The 975MR also provides the highest immunity to false alarms at such industry leading detection range. Features & Benefits ■ Multi spectrum design - for long distance detection and 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 • Relays (3) for Alarm, Fault, and Auxiliary • HART® Protocol for maintenance and asset management ■ High Reliability - MTBF - minimum 150,000 hours ■ Approved to Safety Integrity Level 2 (SIL 2 - TUV) ■ User Programmable via HART® or RS-485 Rosemount 975MR Multi-spectrum Infrared Flame Detector ■ Oil & Gas - Offshore & Onshore process facilities ■ Petrochemical process facilities ■ Automotive manufacturing facilities ■ Power Generation facilities ■ Chemical & Pharmaceutical plants ■ Production, loading & unloading facilities ROSEMOUNT EMERSON.
