Key Features and Advantages
The **Fireye 85UVF1-1CEX** provides explosion-proof UV flame detection for critical combustion systems. Its solar-blind UV tube technology eliminates false alarms from sunlight or hot surfaces, achieving 99.9% immunity to non-flame radiation. The detector’s hermetically sealed stainless steel housing withstands corrosive atmospheres in offshore and chemical processing applications.
Advanced diagnostics: Continuous self-checking circuitry monitors tube integrity and window cleanliness, triggering maintenance alerts. Dual relay outputs support both alarm and fault signals, while the 4–20mA output provides real-time flame intensity data for burner optimization. ATEX/IECEx certification ensures safe operation in Zone 1/21 hazardous areas with gas groups IIB+H2.
Application Areas
Application AreasThe **Fireye 85UVF1-1CEX** is essential for refinery flare stacks, providing reliable flame monitoring under high wind conditions. Cement kilns utilize its high-temperature tolerance for rotary burner supervision. Offshore platform heaters rely on the IP66 rating and marine-grade construction for salt spray environments.
Power generation plants deploy this detector for auxiliary burner control in combined-cycle units. Waste incineration systems benefit from its immunity to false triggers from hot particulates. Petrochemical reformers use the SIL 2-certified design for safety instrumented systems (SIS).
