45RM2-1001 Fireye Scanner

Overview

The Fireye 45RM2-1001 is a self-checking infrared (IR) flame scanner designed for industrial burner management and flame safeguard applications. It is specifically engineered to detect the presence or absence of flames in environments using “dirty” fuels such as oil, coal, or gas. This model is identical in function to the 45RM2-1000 but features a 1-inch BSP (British Standard Pipe) mounting thread instead of NPT. Although now considered an obsolete product by the manufacturer, it remains a critical component in many legacy combustion systems for continuous flame monitoring.

Features

• Infrared (IR) detection using a solid-state lead sulfide detector sensitive to the 700 to 2500 nm range.
• Continuous electronic self-checking mechanism that uses an electronic shutter to verify scanner and signal circuit integrity without moving parts.
• High discrimination capability to distinguish between the target flame and background radiation or adjacent burner flames.
• Integrated 10-LED flame strength bargraph on the rear of the housing to assist with optimal sighting and installation.
• 16-position rotary filter switch to select specific flame flicker frequencies (30 to 180 Hz) for improved signal-to-noise ratios.
• Gain adjustment potentiometer for fine-tuning sensitivity based on specific application requirements.

Applications

The 45RM2-1001 is used primarily with Fireye 25SU3-5166/5168 and 25SU3-2000 amplifiers. It is designed for monitoring burners in large industrial boilers, furnaces, and kilns, especially those utilizing heavy oil or coal where infrared sensing is more effective than ultraviolet. Common industries of use include power plants, pulp and paper mills, and chemical processing facilities. It is suitable for both main flame and pilot monitoring in single or multi-burner configurations.
