95IRS2-1 Fireye Scanner

Overview

The Fireye 95IRS2-1 InSight I is a microprocessor-based, integrated infrared (IR) flame scanner designed to detect the presence or absence of a target flame in single or multi-burner applications. As an “Expanded Model S2,” it features advanced signal processing and internal flame relays, eliminating the need for a remote amplifier. It is engineered to replace older Fireye models like the 45FS1 and 45RM4, providing reliable monitoring through the analysis of flame flicker modulations.

Features

• Infrared (IR) solid-state sensor optimized for coal and oil-fired applications.
• AutoTune technology automatically selects the best modulation frequency and sensor gain with manual override capability.
• Internal flame relay with adjustable ON/OFF thresholds for integrated control.
• Electronic self-checking system ensures continuous operation without a mechanical shutter.
• Eight-character alphanumeric LED display and four-button keypad for local parameter viewing and setpoint selection.
• Four selectable programmable files to store setpoints for different fuels or firing rates.
• Remote communication capability via Fireye Windows-based software.
• Twelve-pin electrical quick-disconnect for simplified wiring and maintenance.

Applications

The 95IRS2-1 is ideal for industrial and commercial burner management systems, particularly those using coal or oil as fuel. It is commonly employed in power stations, steel mills, cement kilns, and multi-burner furnaces where precise flame discrimination is required. The scanner’s ability to store multiple profiles makes it suitable for complex systems with varying fuel types or firing rates.
