4-290-1 Fireye UV Tube

Overview

The Fireye 4-290-1 is a precision replacement ultraviolet (UV) tube flame sensor designed for use in industrial burner management systems. As a critical component for flame supervision, it detects the specific UV radiation emitted by fossil fuel flames while ignoring infrared signals from hot refractory. This vacuum-sealed bulb is engineered to restore peak signal strength to controls, ensuring accurate flame verification during ignition and continuous monitoring for operational safety.

Features

• High-sensitivity ultraviolet sensing technology for precise flame detection
• Specifically tuned to detect wavelengths between 185 and 260 nanometers
• Direct OEM replacement design ensures seamless integration and simplified maintenance
• Standard 4-pin base for rapid and hassle-free field replacement
• Capable of restoring consistent 10-25 microamp DC readings to safeguard controls
• Non-self-checking design optimized for intermittent burner operation
