102531-004 Fireye Fiber Optic

Overview

The Fireye 102531-004 is a high-performance metal-sheathed quartz fiber optic bundle designed for industrial flame monitoring systems. This 100-inch (97.5-inch nominal) assembly is engineered to transmit ultraviolet and infrared radiation from the burner flame to a remotely located flame scanner. It is specifically designed for applications where a direct line-of-sight between the scanner and the flame is obstructed by diffusers, burner internals, or complex sight pipe alignments. The durable metal sheathing provides essential protection for the quartz fiber core against the extreme heat and mechanical stresses typical of combustion environments.

Features

• High-temperature quartz fiber core optimized for both UV and IR signal transmission.
• Flexible metal sheathing protects the delicate optical fibers from heat, abrasion, and physical damage.
• 100-inch length provides significant reach for remote scanner mounting away from high-heat zones.
• Designed to maintain optical signal clarity and stability in demanding industrial settings.
• Facilitates flame detection in complex burner geometries where traditional mounting is impossible.
• OEM-level construction ensures seamless compatibility with specific Fireye scanner series.

Applications

The Fireye 102531-004 is primarily used in large-scale industrial and commercial combustion systems, including power plant boilers, recovery boilers, and furnaces. It is the ideal solution for burners with internal obstructions like diffusers or where the scanner must be located outside a windbox for maintenance access or protection from ambient heat. It is specifically utilized in Fireye InSight and Phoenix series scanner installations that require specialized fiber optic routing to ensure reliable flame safeguard monitoring.
