975UF Ultra Fast UV/IR Flame Detector

Ultra-fast UV/IR flame detector — detects fire in under 20 milliseconds using a unique dual sensor with selectable UV and IR channels. The fastest detector in the 975 family — built for explosion-suppression and rapid-response fire-control loops where a 100 ms standard detector is too slow (munitions, propellant manufacturing, high-pressure hydrogen storage, fuel-mix piping). UV and IR channels can be used separately or combined for application-specific false-alarm rejection. SIL 2 prior-use FMEDA.
