95IRS4-1 Fireye Flame Scanner

Overview

The Fireye 95IRS4-1 InSight Series 4 is an integrated, microprocessor-based infrared (IR) flame scanner designed for industrial burner management systems. By combining flame detection, amplification, and safety relays into a single detection head, it eliminates the need for separate flame amplifier modules. This model features a high-performance infrared sensor optimized for detecting the flicker of gas and oil flames while providing superior discrimination in multi-burner environments.

Features

• Integrated Design: Houses the sensor, amplifier, safety determination, and flame relay in one compact unit.
• Advanced Discrimination: Utilizes 21 selectable modulation frequencies (flame flicker) to distinguish the target flame from background radiation or adjacent burners.
• Internal Relays: Includes independently adjustable Flame and Fault relays.
• User Interface: Features a 2-line by 16-character alpha-numeric OLED display with a five-pushbutton keypad for local configuration and status monitoring.
• Memory Files: Supports four selectable memory files to store settings for different fuels or firing rates.
• Auto-Config: Includes an automated setup function to select optimal sensor gain and frequency for reliable flame ON/OFF detection.
• Quick Disconnect: Equipped with a 12-pin male quick-disconnect for simplified wiring and maintenance.

Applications

The 95IRS4-1 is ideal for complex combustion applications requiring high levels of sophistication, including large multi-burner boilers, furnaces, and kilns. It is specifically suited for monitoring infrared radiation produced by the combustion of fossil fuels such as natural gas, propane, and various fuel oils. Common installations include industrial gas burners, duct burners, waste gas units, and incinerators, particularly where space is limited and an integrated solution is preferred.
