Optical flame detectors for process industry applications
Emerson’s Rosemount 975 optical flame detectors are designed to perform in the harshest environmental conditions and connect directly to alarm or automatic fire extinguishing systems. They can be used in many 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. They feature integrated ultraviolet and infrared sensor technology that is designed to detect 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 C (-67 to 185 F); and multiple output options for maximum flexibility and compatibility. The Rosemount 975 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 (40 ft) from the detector, which is designed to eliminate the need for personnel to stand on scaffolding or supports to access the detector.
