Emerson has announced the release of the Rosemount 975 flame detectors, a line of optical flame detectors designed to perform in the harshest environmental conditions and connect directly to alarm or automatic fire extinguishing systems.

The range incorporates a variety of flame detection technologies that will provide optimal coverage for a wide range of process industries, including upstream oil and gas installations, chemical plants and refineries. Multispectrum 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, and metal and inorganic fires with robust false alarm immunity.

Built to be durable and weather-resistant, the flame detectors feature heated windows for operation in harsh weather conditions, such as snow, ice or condensation; broad operating temperature ranges from -55°C to 85°C; and multiple output options for maximum flexibility and compatibility. The line is approved to Safety Integrity Level (SIL) 2 (TÜV). The detectors can even be tested in-field with a specially designed flame simulator at distances of up to 12 m from the detector, eliminating the need for personnel to stand on scaffolding or supports to access the detector.
