Flame detectors keep personnel and facilities safe

19 July 2016

Emerson has introduced  the Rosemount 975 flame detectors, a range of optical flame detectors designed to perform in harsh environmental conditions and connect directly to alarm or automatic fire extinguishing systems.

The new range incorporates a variety of flame detection technologies designed to provide optimal coverage for a wide range of process industries, including upstream oil and gas installations, chemical plants, and refineries. 

Multi-spectrum infrared sensor technology detects hydrocarbon fuel and gas fires as well as ‘invisible’ hydrogen fires with wide area coverage and strong false alarm immunity. Integrated ultraviolet and infrared sensor technology rapidly detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires with robust false alarm immunity.

The  Rosemount 975 flame detectors feature heated windows for operation in harsh weather conditions, such as snow, ice, or condensation; broad operating temperature ranges from -55 to +85 degrees  C; and multiple output options for maximum flexibility and compatibility. 

The range is also approved to Safety Integrity Level (SIL) 2 (TÜV). The detectors can be tested in-field with a specially designed flame simulator at distances of up to 12m from the detector, eliminating the need for personnel to stand on scaffolding or supports to access the detector.
