Fireye UV1A Series UV Flame Scanners. The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from the flame. In the absence of UV radiation, the gas acts as an insulator between two electrodes that are mounted inside the tube. These electrodes are energized continuously by a high voltage. During combustion, UV radiation ionizes the gas, causing current pulses to flow between the electrodes. These current pulses result in a flame signal which is transmitted to the amplifier in the control, where it is processed to energize or hold in the flame relay.

Fireye UV90 Series UV Flame Scanners. The UV90 Series Scanners are state-of-the-art ultraviolet flame scanners specifically designed for both front and lateral (90°) mounting, offering enhanced flexibility and performance in a variety of flame detection applications. These versatile UV scanners are engineered to provide a clearer and more accurate view of the flame in applications where line-of-sight positioning can impact performance.

Fireye UV90L Series UV Flame Scanners. The UV scanner is ideally suited for gaseous fuels (natural gas & propane). However, it can be used in detecting flames from standard fuel gases, some waste gases and light oil fuels such as No. 2 oil. Flames from heavier oils can be detected with UV scanners but the unburned fuel shroud and/or atomization shroud can block the passage of the UV from the flame zone to the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil heavier than No. 2, and some installations where waste gases are burned together with natural gas as the main flame.
