Ultra-fast detection with extended coverage
The SharpEye 40/40D-I delivers ultra-fast flame detection in under 50 milliseconds, providing critical early warning in high risk environments. Its extended detection range of up to 90 metres significantly increases coverage area, reducing system complexity while enhancing overall protection.
QuadSense technology for superior false alarm immunity
Integrating four infrared sensors, the QuadSense platform improves the detector’s ability to distinguish real flame events from non-flame radiation sources. This results in proven immunity to false alarms while maintaining the highest sensitivity to hydrocarbon based fires.
Built for extreme industrial environments
Engineered for operation in temperatures from minus 60 C to plus 85 C, the 40/40D-I is designed for onshore and offshore oil and gas, petrochemical facilities, power generation, hydrogen production, mining and other hazardous applications. With heated optics, continuous built in testing and SIL3 compatibility, it ensures reliable performance where safety is critical.
