Broad-spectrum UV/IR fire detection
The SharpEye 40/40D-LB is engineered to detect a wider variety of fire types beyond standard hydrocarbon flames. In addition to fuel and gas fires, it can identify hydrogen, hydroxyl, metal and inorganic fires, making it suitable for complex industrial environments where diverse ignition sources exist.
Flexible detection with dual optical sensors
The selectable UV and IR channels allow the detector to operate independently or in combined mode depending on application requirements. This flexibility supports reliable detection while maintaining strong immunity to nuisance alarms caused by non-flame radiation.
Built for demanding hazardous environments
Designed to operate in temperatures from minus 60 C to plus 85 C, the 40/40D-LB includes heated optics, continuous built in testing and internal event logging to ensure consistent performance. With worldwide hazardous area certifications and SIL3 compatibility, it is suited to oil and gas, chemical, hydrogen, aerospace and heavy industrial facilities.
