61-4894-1 Fireye CARRIER Assembly

Overview

The Fireye 61-4894-1 is a high-performance inner carrier assembly designed for industrial flame monitoring systems. As a critical component of a fiber optic scanner system, this 7-foot (2134 mm) assembly houses a glass fiber optic bundle that transmits flame radiation from the burner to the scanner electronics. It is specifically engineered for environments where a direct line of sight to the flame is obstructed by burner components such as movable vanes or air compartments.

Features

• Flexible glass fiber optic bundle designed for high-temperature durability and efficient light transmission.
• 7-foot length provides significant reach for complex burner configurations and deep windboxes.
• Precision-engineered ferrule ends to ensure stable optical alignment and consistent signal strength.
• Rugged construction suitable for the demanding conditions of industrial combustion environments.
• Designed for seamless integration into Fireye outer carrier assemblies and compatible scanner electronics.

Specifications

Applications

The Fireye 61-4894-1 is used in large-scale industrial and utility burner applications, including steam and hot water boilers, power plant boilers, and petrochemical process heaters. It is ideal for monitoring flames in multi-burner furnaces where individual flame discrimination is required and where the burner geometry prevents the use of standard surface-mounted flame scanners.
