Spectrex 40/40UFI Ultra Fast Triple IR (IR3) Flame Detector


The Spectrex 40/40UFI is an Ultra-fast multispectrum IR3 flame detector, that detects hydrocarbon fuel and gas fires at long distances. The Spectrex 40/40UFi is designed to detect an explosive 1 ft (0.3m) diameter gas cloud explosion in max. 50 msecs for 1ft diameter sphere methane-air mixture explosion at 66 ft (20m) with the highest immunity to false alarms. The Spectrex 40/40UFI IR3 can also detect a 1 ft2 (0.1m2) gasoline/n-Heptane pan fire at up to 300 ft (90m).

Spectrex 40/40UFI Ultra Fast Triple IR (IR3) Flame Detector

The Spectrex 40/40UFi is part of the Spectrex 40/40 Series, which are the most durable and weather resistant range of flame detectors. The 40/40UFi has a heated window to eliminate condensing and icing, HART capability for digital communications; lower power requirements; and a compact, lighter design. Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved per IEC 61508.
