UV90L-1 Fireye Scanner

UV90L-1 Fireye Scanner

UV scanner, Front and side (90°) lateral view, terminal block hook-up

The UV90L Series Scanner is designed for front and lateral (90°) mounting which, in some applications allow the scanners to obtain a clearer view of the flame.
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.

Overview

The Fireye UV90L-1 is a high-sensitivity, non-self-checking ultraviolet (UV) flame scanner designed to detect flame presence in industrial and commercial combustion applications. It is part of the UV90L Series and is engineered to work seamlessly with Fireye BurnerPRO, MBCE, and NXF4000 burner management systems. The scanner utilizes a quartz UV tube filled with gas that ionizes in the presence of UV radiation, transmitting a signal to the control amplifier to maintain or energize the flame relay. Its design is particularly effective for gaseous fuels like natural gas and propane.

Features

• Dual Mounting Options: Supports both front and lateral (90-degree) mounting for a flexible and clear view of the flame.
