The FL500-H2 optical flame detector monitors for radiation emitted by a hydrogen flame in both the ultraviolet (UV) and infrared (IR) spectral ranges. This combination of UV/IR provides a fast response time and increased false alarm immunity to radiation sources for reliable protection.

Features:

• Proven technology. UV / IR flame detection uses an ultraviolet and an infrared detector to monitor for hydrogen flames, increasing false alarm immunity by measuring two different flame spectra
• Wide field of view. The 130° field of view covers a greater distance
• Self-Check for safety integrity. Continuous Optical Path Monitoring (COPM) performs a self-check every two minutes to ensure the optical path is clear and the electronic circuitry is functional.
• Test anytime, anywhere. Test easily with our exclusive TL105 test lamp, allowing the FL500 UV/IR flame detector to be safely tested in real fire conditions with simulated flame flicker.
• Resistant to extremes. The wide operating temperature range (-55°C to +85°C) allows use in extreme environments
• Status at a glance. Three LED status indicators for warning, alarm and normal operation.
• Robust housing. 316 stainless steel housing to withstand the toughest environments.
• Multiple output options. Industry standard 4-20 mA (source or sink analog), Modbus, HART, relays
