Proven Flame Safety for Industrial Combustion Systems

Flame detection is one of the most critical safety functions in industrial combustion systems. Whether in power generation, oil and gas processing, or heavy manufacturing, accurate flame monitoring is essential to prevent fuel accumulation, equipment damage, and hazardous operating conditions.

The Fireye Ultraviolet (UV) Flame Detector 85UVF4-1 combined with mounting accessory 35-318-1 is a trusted solution designed to provide fast, reliable flame detection in demanding industrial environments worldwide.

Overview of Fireye 85UVF4-1 UV Flame Detector

The Fireye 85UVF4-1 is a high-performance ultraviolet flame detector engineered to sense the UV radiation emitted by hydrocarbon flames. It is widely used in industrial burners and boilers where fast flame recognition and dependable operation are mandatory.

Paired with the 35-318-1 mounting assembly, the detector can be installed securely and aligned precisely for optimal flame viewing, ensuring consistent detection and long-term reliability.

Why Ultraviolet Flame Detection Matters

Ultraviolet flame detectors operate by sensing the specific UV wavelengths produced during combustion. Unlike visible light sensors, UV detectors are largely immune to interference from hot refractory surfaces, sunlight, or incandescent lighting.

This makes UV flame detection particularly effective in industrial environments where false signals must be avoided. The Fireye 85UVF4-1 is designed to deliver fast response times and accurate flame discrimination, supporting safe burner management operations.

Key Features of Fireye 85UVF4-1

One of the most important advantages of the 85UVF4-1 is its high sensitivity to ultraviolet radiation produced by hydrocarbon flames. This allows for rapid flame recognition during ignition and continuous monitoring during operation.

The detector is built with industrial-grade durability, supporting long service life in high-temperature, vibration-prone environments. Its robust construction makes it suitable for both indoor and outdoor installations.

In addition, the 85UVF4-1 is compatible with a wide range of Fireye flame safeguard and burner management systems, enabling seamless integration into existing control architectures.

The Role of the 35-318-1 Mounting Assembly

Proper installation is critical to flame detector performance. The 35-318-1 mounting assembly is designed to ensure correct positioning, alignment, and protection of the UV detector.

This mounting accessory allows installers to aim the detector precisely at the flame root, maximizing signal strength and minimizing false readings. It also supports maintenance access and mechanical stability, which are essential for long-term reliability.
