45RM4-1001 Fireye Scanner

Overview

The Fireye 45RM4-1001 is a self-checking infrared flame scanner designed for industrial burner management and flame safeguard applications. It utilizes a solid-state lead sulfide (PbS) detector to monitor flame flicker across a wide spectral range. This model is engineered to provide high discrimination between the target flame and background radiation, making it particularly effective in challenging environments. Note: This product has been discontinued and is typically replaced by the InSight II 95IRS2-1 series.

Features

• Infrared (IR) sensing technology with a spectral range of 700 to 2500 nm.
• Electronic self-checking system eliminates the need for a mechanical shutter.
• 16-position rotary selector switch for adjusting flame flicker frequency (30 to 180 Hz).
• Adjustable gain potentiometer for precise sensitivity tuning.
• 10-segment LED bargraph on the rear for real-time flame strength indication.
• BGC (Background Gain Control) to handle variations in background brightness without sensor washout.
• Quick disconnect design for simplified installation and maintenance.

Applications

The 45RM4-1001 is used primarily with Fireye 25SU3 and 25SU5 series amplifiers. It is optimized for detecting “dirty fuels” such as pulverized coal, heavy oil, and gas where high discrimination is required to distinguish the main flame from background radiation or adjacent burner flames. It is commonly applied in single or multi-burner utility and industrial boilers, as well as in low-NOx burner configurations.
