40/40D-L4B Flame Detector

40/40D-L4B Flame Detector

The SharpEye 40/40D-L4B is an ultra-fast UV/IR flame detector featuring selectable UV and IR channels that can operate independently or combined, delivering detection speeds under 20 milliseconds for hydrocarbon-based fuel and gas fires. Unlike IR3-based models in the 40/40 range, the 40/40D-L4B uses dual optical sensing technology to provide rapid response and reliable discrimination in applications where UV/IR detection is preferred. Designed for extreme industrial environments, it offers exceptional false alarm immunity, wide operating temperature capability and long-term reliability to keep a SharpEye on your safety.

Ultra-fast UV/IR detection for hydrocarbon fires

The 40/40D-L4B delivers detection speeds under 20 milliseconds, providing critical early warning for hydrocarbon-based fuel and gas fires. Its dual optical sensor design allows it to respond rapidly while maintaining reliable performance in complex industrial environments.

Selectable detection modes for flexible deployment

With independent UV and IR channels, the detector can be configured to suit different site conditions. This flexibility helps optimise detection performance while maintaining strong immunity to nuisance alarms caused by non-flame radiation sources.

Engineered for harsh and hazardous environments

Built to operate in temperatures from minus 60 C to plus 85 C, the 40/40D-L4B is suited to oil and gas, petrochemical, power generation and other high-risk sectors. With continuous built-in testing, heated optics and SIL3 compatibility, it provides dependable flame detection where safety integrity is critical.
