UV1A12 Fireye Scanner

Overview

The Fireye UV1A12 is a miniature, non-self-checking ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. It detects ultraviolet radiation emitted by fossil fuel flames, such as natural gas and No. 2 oil, while remaining “solar-blind” to infrared radiation from hot refractory surfaces. This scanner is engineered to provide rapid and dependable flame verification, ensuring safe burner ignition and continuous monitoring in demanding heating environments.

Features

• Ultraviolet (UV) sensing technology for accurate, interference-resistant flame detection.
• Compact, miniature design ideal for space-constrained burner fronts.
• Non-self-checking operation suitable for burners that cycle at least once every 24 hours.
• Solar-blind sensor eliminates interference from infrared radiation emitted by hot surfaces.
• Rugged construction with a quartz UV tube and stainless steel housing.
• Rapid response time to ensure safe pilot and main flame authentication.

Applications

The UV1A12 is compatible with a wide range of Fireye controls, including M-Series, M-Series II, MicroM, FlameWorx, MB-2, D-Series, Flame-Monitor, BurnerLogix, and Nexus systems. It is widely used in commercial and industrial boilers, furnaces, and process heating equipment requiring continuous flame supervision for gaseous fuels and light oils. It is particularly effective for installations where line-of-sight access to the flame is required via a straight sight pipe.
