45RM1-1001EX Fireye HOUSING & Scanner

Overview

The Fireye 45RM1-1001EX is a high-performance infrared (IR) flame scanner assembly integrated into a rugged explosion-proof housing. Designed for the most demanding industrial and utility environments, this system is specifically engineered to monitor flames from fuels that produce strong infrared signatures, such as pulverized coal and oil. By combining the 45RM1-1000 scanner with a specialized NEMA 7-rated enclosure, the 45RM1-1001EX provides reliable flame detection and safety monitoring in hazardous locations where explosive gases or dust may be present.

Features

• Infrared (IR) Sensing Technology optimized for the detection of oil and coal flames by monitoring the primary combustion zone.
• Explosion-Proof Housing rated NEMA 7 for Class 1, Div 1 & 2 (Groups C, D) and Class 2, Div 1 & 2 (Groups E, F, G) hazardous environments.
• Self-Checking Circuitry ensures the scanner and electronics are functioning correctly by utilizing a mechanical shutter to periodically block the sensor’s view.
• Advanced Discrimination capabilities allow the system to distinguish between the target burner flame and background radiation or fireballs from other burners.
• Quick-Disconnect Design on the internal scanner electronics allows for easy removal and installation for maintenance and lens cleaning without disturbing the sight pipe.
• Durability featuring a die-cast aluminum housing designed to withstand harsh industrial conditions and high temperatures.

Applications

The Fireye 45RM1-1001EX is ideally suited for monitoring fossil fuel-fired burners in large utility boilers, industrial power plants, and chemical processing furnaces. Its robust design and explosion-proof rating make it the standard choice for refineries, petrochemical plants, and any facility requiring flame safeguard protection in hazardous zones. It is particularly effective for monitoring steam-atomized oil or coal flames where traditional ultraviolet scanners may be less effective due to high background radiation or signal attenuation.
