95IRS2-2CG Fireye Scanner

Overview

The Fireye 95IRS2-2CG InSight I is a microprocessor-based, integrated flame scanner designed for industrial burner management. As an “Expanded” S2 model, it features advanced solid-state infrared (IR) sensing technology and is specifically engineered as a fiber-optic version to monitor flames in challenging environments where a direct line of sight is obstructed. By integrating the detector and amplifier into a single unit, it eliminates the need for remote flame amplifiers, providing a direct relay output and 4-20mA signal for flame strength.

Features

• Infrared (IR) Sensing: Solid-state sensor optimized for detecting modulations in coal and oil-fired flames.
• Fiber-Optic Compatibility: Designed for use with fiber-optic inner carrier assemblies to reach inaccessible burner locations.
• Electronic Self-Checking: Includes internal self-diagnosis to ensure fail-safe operation without the need for a mechanical shutter.
• Integrated Design: Houses both the sensor and the flame relay with adjustable ON/OFF thresholds in one compact unit.
• User Interface: Features an eight-character alpha-numeric LED display and a four-button keypad for local configuration and monitoring.
• AutoTune Functionality: Expanded S2 model capability that automatically selects the best modulation frequency and gain for optimal flame discrimination.

Applications

The 95IRS2-2CG is ideally suited for large multi-burner boilers and furnaces in industries such as power generation, petrochemical processing, and pulp and paper manufacturing. It is specifically used in applications firing heavy fuels like coal or oil where the scanner must be mounted remotely via fiber optics. Its high discrimination capabilities make it effective for distinguishing the target flame from background radiation in complex combustion chambers.
