45RM4-1000 Fireye Scanner

Overview

The Fireye 45RM4-1000 is a rugged, self-checking infrared (IR) flame scanner designed to detect the presence and absence of flame in industrial combustion systems. It features a solid-state lead sulfide photodetector and a frequency-tuned circuit housed in a durable die-cast aluminum enclosure. This scanner is specifically engineered to provide high discrimination, allowing it to distinguish between a target flame and background radiation or adjacent flames in multi-burner environments. It employs an electronic shutter for continuous self-checking without the wear of mechanical parts.

Features

• Infrared (IR) detection using a solid-state lead sulfide cell with a range of 700 to 2500 nm.
• Continuous electronic self-checking for fail-safe flame monitoring.
• 16-position rotary frequency selector to tune the scanner to specific flame flicker frequencies (30 to 180 Hz).
• Integral 10-segment LED bar graph on the rear of the housing to indicate flame strength and assist in sighting.
• Adjustable gain potentiometer for fine-tuning sensitivity to the application.
• Quick-disconnect electrical connection for easy installation and maintenance.
• Die-cast aluminum housing for protection in harsh industrial environments.

Specifications

• Model Number: 45RM4-1000
• Supply Voltage: 24 VDC (typically provided by a compatible Fireye amplifier).
• Current Rating: 100 mA per scanner.
• Mounting: 1-inch NPT threaded mount.
• Operating Temperature Range: -13 F to 150 F (-25 C to 65 C).
• Humidity Range: 0% to 95% relative humidity, non-condensing.
• Purge Air Requirement: 4.0 SCFM (113L/min) at 3/8 inch threaded inlet.
• Shipping Weight: Approximately 6.8 lbs (3.1 kg).
• Agency Approvals: CSA and FM (CE approved when used with a compatible amplifier).

Applications

The 45RM4-1000 is ideal for monitoring dirty fuels such as pulverized coal, oil, and gas where low to mid-range flicker frequencies are present. It is designed for use in single or multiple burner configurations, including power plant boilers, industrial process furnaces, and electric utility boilers. It is compatible with Fireye 25SU3 and 25SU5 series flame safeguard controls and amplifiers. Typical applications include Lo-NOx burners and installations where high discrimination from background fireballs is necessary for safety.
