ABB UR600IR/BGT Infrared Flame Scanner Module

Product Overview

The UR600IR/BGT is a high-precision infrared (IR) flame monitoring module engineered for continuous supervision in demanding industrial combustion environments. By analyzing both infrared radiation intensity and specific flame flicker characteristics, this scanner effectively discriminates between an active burner flame and background thermal interference or refractory glow. The UR600IR/BGT is a critical safety component for boilers and furnaces, featuring an integrated self-checking mechanism that performs continuous internal diagnostics to eliminate the risk of false-flame signals. Its robust, explosion-proof construction ensures reliable performance in high-temperature zones and hazardous areas.

Advanced Flame Discrimination and Safety

The UR600IR/BGT utilizes advanced spectral filtering to focus on the infrared signature of combustion. Unlike standard sensors, it does not rely solely on light intensity; it processes the "flicker" or dynamic frequency of the flame. This dual-parameter approach prevents the system from being "fooled" by hot refractory brickwork, which emits steady IR radiation but lacks the characteristic flicker of a live flame. For restricted or extremely high-temperature mounting locations, the module’s compatibility with fiber-optic assemblies allows the sensitive electronics to be positioned away from direct heat while maintaining a clear "view" of the ignition zone.
