61-6625 Fireye Scanner

Overview

The Fireye 61-6625 is a 45FS1 infrared flame scanner specifically designed for use with fiber optic assemblies in industrial burner management systems. It is engineered for applications where a direct line-of-sight is difficult to achieve or where the environment is too harsh for standard scanners. This scanner provides reliable flame detection by monitoring infrared radiation, making it ideal for detecting coal, oil, and gas flames in complex boiler or furnace configurations.

Features

• Designed for seamless integration with Fireye fiber optic bundles and light pipes.
• Utilizes a lead sulfide cell (infrared detector) for high-sensitivity flame sensing.
• Provides reliable flame discrimination in multi-burner environments.
• Remote detection capability allows the scanner electronics to be mounted away from high-heat zones.
• Rugged construction suitable for demanding industrial combustion applications.

Specifications

• Model Number: 61-6625 (45FS1)
• Sensor Type: Infrared (IR) Lead Sulfide
• Compatibility: Fireye Type 25SU3 (Models -2000, -2100), 4170, and 4172 controls.
• Mounting: Requires fiber optic adapter kit (e.g., 61-6702) for specific installations.
• Operating Temperature: Scanner electronics typically rated for -40 degree F to 140 degree F (-40 degree C to 60 degree C).
• Voltage: Usually 24VDC when used with compatible amplifiers.

Applications

The 61-6625 scanner is widely used in power generation, petrochemical plants, and oil and gas refineries. It is specifically intended for burner-boiler applications where the scanner cannot be mounted directly in the blast tube. It is best suited for providing reliable detection and discrimination on coal and oil flames, as well as single-burner or front-fired gas flames in utility boilers, kilns, and large industrial furnaces.
