61-5234 Fireye Scanner

Overview

The Fireye 61-5234 is a high-performance 45RM2 infrared flame scanner specifically designed for use with fiber optic bundle assemblies. This scanner is engineered to detect the low-frequency flickering of infrared radiation from fuel flames, making it ideal for monitoring burner flames in environments where a direct line of sight is difficult to achieve. It works in conjunction with Fireye 25SU3 and 25SU5 flame safeguard controls to provide reliable flame monitoring and discrimination in industrial multi-burner environments.

Features

• Infrared (IR) sensing technology designed to detect flame flicker while ignoring background radiation from hot refractory surfaces.
• Compatible with glass or quartz fiber optic bundles to allow for remote sensing in high-temperature or physically constrained locations.
• Integral self-checking shutter mechanism that continuously verifies the integrity of the scanner’s electronics and sensor.
• High discrimination capabilities to distinguish between the target burner flame and adjacent or background flames.
• Durable construction suitable for rugged industrial applications.

Specifications

• Model Number: 61-5234 (45RM2 type)
• Detection Type: Infrared (IR)
• Compatibility: Fireye 25SU3 and 25SU5 series amplifiers/controllers
• Optical Interface: Designed for connection to Fireye fiber optic assemblies
• Operating Temperature: -40 degrees F to 150 degrees F (-40 degrees C to 65 degrees C) at the scanner housing

Applications

The 61-5234 scanner is primarily used in industrial power plants, refineries, and large chemical processing facilities. It is particularly effective for monitoring flames in utility boilers and furnaces where traditional mounting is not feasible due to burner geometry or extreme heat, requiring the flexibility of a fiber optic extension. It is suitable for flames produced by various fuels, including natural gas, oil, and pulverized coal.
