975UR Ultraviolet Infrared Flame Detector

Dual-spectrum UV/IR flame detector — senses radiant energy in both the short-wave UV and short-wave IR portions of the spectrum simultaneously, providing high false-alarm immunity (welding, lightning, sunlight reflection) while detecting hydrocarbon-based fuel and gas fires. The workhorse 975 variant for general process / refining / petrochemical fire detection. SIL 2 prior-use FMEDA. Variable-area coverage from a single detector reduces installed sensor count vs. older single-spectrum detectors.
