40/40D-M Flame Detector
The SharpEye 40/40D-M is a multispectrum QuadSense IR3 flame detector engineered for hydrogen applications while maintaining extended hydrocarbon fire coverage. It detects hydrogen flames at distances up to 50 m and hydrocarbon-based fuel and gas fires up to 90 m, with response times under 50 milliseconds. Built on proven Triple IR technology with four integrated infrared sensors, the 40/40D-M delivers enhanced flame discrimination, high sensitivity and exceptional immunity to false alarms. Designed for harsh industrial environments, it provides reliable performance where hydrogen and hydrocarbon risks coexist.

Optimised for hydrogen and hydrocarbon fire detection
The SharpEye 40/40D-M is specifically engineered to detect hydrogen flames at distances up to 50 metres, while also delivering long-range hydrocarbon detection up to 90 metres. This makes it ideal for facilities handling hydrogen production, storage or fuel cell applications alongside traditional hydrocarbon processes.
QuadSense IR3 technology for superior discrimination
Using four infrared sensors, the QuadSense platform enhances the detector’s ability to differentiate true flame signatures from background radiation. This results in strong immunity to false alarms while maintaining high sensitivity and rapid response in demanding industrial conditions.
Engineered for harsh and hazardous environments
With an operating temperature range from minus 60 C to plus 85 C, heated optics and continuous built in testing, the 40/40D-M is designed for extreme environments. It is SIL3 compatible and certified for hazardous areas worldwide, supporting safety critical applications across oil and gas, hydrogen facilities, petrochemical plants and power generation.
