NET SAFETY/ROSEMOUNT offers the most comprehensive and advanced detection technologies available.
IR flame detectors can detect hydrocarbon or hydrogen flames. It functions as a sensing device to detect and indicate if 975 flame detector manual flames are burning or ignition has been lost. The mechanisms used to detect flames can make flame detectors faster to react than smoke or heat detectors. The FSL100 Series of flame detectors delivers robust, fast, and reliable detection of flaming fires in a wide range of applications.

Flame Detectors Rosemount Analytical 975UR Flame Detector Incorporates ultraviolet and infrared sensors for detecting hydrocarbon-based fuel and gas fires with high false alarm immunity.
Flame detectors respond to the radiant emissions from a flame — so, the first and perhaps most important consideration when selecting detectors is that they accurately and reliably identify flames. Because ethylene glycol flames produce little infrared (IR) light, the IR flame detectors installed to detect natural gas flames didn’t offer sufficient coverage to protect against alcohol fires. Detection equipment must suit the particular hazard; the devices’ spectral responses must match the spectral emissions of the flames to be detected. Flame Detectors Rosemount Analytical 975MR Flame Detector Multi-spectrum infrared sensing detects hydrocarbon fuel and gas fires with superior reliability and high false alarm immunity.
UV detectors do best when detecting clean flames (i. The detector discriminates between flames and other light sources by responding only to particular optical wavelengths and flame flicker. The ApolloMAR signals to the Control and Indicating Equipment using an interrupt feature within the Apollo Digital Protocol. Few plants fail to choose devices based on the process fluids present in the coverage area but many sites often don’t consider other fire hazards.
