Fireye UV1A12 Ultraviolet Flame Scanner with 12' Cable and 1/2" NPT Connector

The Fireye UV1A12 is a miniature ultraviolet (UV) flame scanner designed for reliable combustion monitoring in industrial burner applications. This non-self-checking scanner features a 1/2" NPT mounting connector and comes equipped with a 12-foot flexible conduit cable rated for Tray Cable - Exposed Run (TC-ER), complying with UL 1569 standards for metal-clad cable crush and impact requirements.

Key Features:

• Ultraviolet flame detection technology for accurate combustion monitoring
• Non-replaceable quartz UV tube filled with gas that ionizes when struck by UV radiation
• 12-foot TC-ER rated cable with 1/2" NPT threaded connector
• Compatible with multiple Fireye control systems including M-Series, M-Series II, MicroM, FlameWorx, MB-2, and D-Series
• Works with Flame-Monitor, BurnerLogix, and Nexus systems
• Operating temperature range: -40°F to 200°F (-40°C to 94°C)
• Operating voltage: 560 VAC at 120V or 230V, 50/60 Hz

Application: The UV1A12 scanner is recommended for detecting flames from standard fuel gases, some waste gases, and light oil fuels such as No. 2 oil. During combustion, UV radiation ionizes the gas in the tube, causing current pulses to flow between internal electrodes. These pulses generate a flame signal transmitted to the amplifier in the control system, where it's processed to energize the flame relay. This scanner requires a compatible flame amplifier for operation.

Note: For heavier fuel oils (above No. 2) or certain waste gas applications, infrared detection may be more suitable to prevent nuisance trips caused by fuel shrouding.
