SB49602-91 Fireye UV Scanner

Overview

The Fireye SB49602-91 is a high-performance, self-checking ultraviolet (UV) flame scanner engineered for continuous monitoring in demanding industrial combustion environments. Designed as a replacement for the Eclipse 49602-91, this scanner is a critical component for industrial burner control systems, ensuring secure and efficient combustion by detecting UV radiation emitted by burner flames. It features an integrated mechanical shutter that performs automatic self-checking routines every ten seconds to verify the operational integrity of the scanner and the electronics, enhancing overall system safety by detecting potential sensor failures or “runaway” conditions.

Features

• Ultraviolet (UV) flame sensing technology for accurate and reliable detection of gas and oil flames.
• Automatic self-check function with a long-life push-pull electromagnetically driven mechanical shutter that verifies scanner integrity every 10 seconds.
• High-quality fused silica quartz lens for superior signal transmission and durability.
• Rugged machined alloy housing with seals designed to withstand demanding industrial conditions.
• Continuous operation capability, making it suitable for burners that are not periodically cycled.
• Easy maintenance design that allows for replacement without disturbing existing wiring.

Applications

The SB49602-91 is designed for use in commercial and industrial combustion systems, including boilers, furnaces, and process heating equipment. It is specifically compatible with Eclipse-series burner control systems and Fireye SB-Series (MB-Series) burner management systems. It is ideally suited for continuous combustion monitoring where the burner remains ignited for long periods, providing real-time flame verification and protection for both gas and oil-fired equipment.
