61-4892-2 Fireye Scanner

Overview

The Fireye 61-4892-2 (45RM1) is a specialized flame scanner designed to work in conjunction with fiber optic assemblies. It is specifically engineered to detect flames in obstructed or high-heat burner zones where a standard line-of-sight scanner cannot be utilized. By using a fiber optic bundle to transmit flame radiation to a remote sensor, the 45RM1 is ideal for isolating individual flames within large boiler fireballs, ensuring reliable monitoring and safety in complex industrial combustion environments.

Features

• Remote flame sensing capabilities for obstructed or high-heat combustion zones.
• Accurate detection and isolation of individual flames even within large fireballs.
• Fiber optic bundle technology for transmitting radiation to a remote detector housing.
• Durable construction featuring a cast aluminum housing and stainless steel fiber optic sheathing.
• Support for skew lens angles to optimize signal acquisition.
• Compatible with Fireye flame amplifier modules and 45FS1 series control systems.

Specifications

• Part Number: 61-4892-2 (Scanner Head Assembly 45RM1)
• Detection Method: Fiber optic transmission with remote detector.
• Housing Material: Cast aluminum.
• Sheathing: Stainless steel for the fiber optic bundle.
• Temperature Rating: Up to 800 degrees F (427 degrees C).
• Mounting: Objective lens mounts near the windbox-furnace interface.

Applications

The 61-4892-2 is primarily used in industrial and utility boilers, fossil fuel-fired furnaces, and refinery or petrochemical burner systems. It is particularly effective in large combustion chambers containing multiple burners where individual flame discrimination is required. It is designed for use with Fireye’s range of flame safeguard controls, providing a critical safety link by monitoring the presence or absence of flame in demanding industrial settings.
