Fireye 85UVF3-1 Ultraviolet Flame Detector
Fireye 85UVF3-1 Ultraviolet Flame Detector – Product Overview
The Fireye 85UVF3-1 ultraviolet flame detector is a high-performance flame sensing device designed for industrial combustion safety systems. It plays a critical role in burner management systems by confirming flame presence and enabling rapid shutdown in the event of flame failure.
Fireye has long been recognized as a global leader in flame monitoring and combustion control technology. The 85UVF3-1 model continues this legacy by offering precise ultraviolet flame detection, rugged construction, and dependable operation in demanding industrial environments.
This detector is widely used in applications where safety, reliability, and fast response times are essential, including power generation, oil and gas processing, petrochemical plants, steel mills, cement kilns, and large industrial boilers.
How Ultraviolet Flame Detection Works
Ultraviolet flame detectors operate by sensing UV radiation emitted by hydrocarbon flames during combustion. Unlike visible light or infrared sensors, UV detectors are highly selective, responding only to the specific wavelength range produced by active flames.
The Fireye 85UVF3-1 is engineered to detect ultraviolet radiation typically between 185 and 260 nanometers, allowing it to quickly and accurately confirm flame presence. This narrow detection range helps minimize false signals caused by ambient light, hot surfaces, or electrical noise.
Because UV radiation disappears almost instantly when a flame is extinguished, the 85UVF3-1 provides rapid flame failure detection, enhancing overall system safety.
