Designed for demanding industrial environments, this module provides continuous flame monitoring with a built-in SPST relay and optically isolated 4–20mA analog output. The advanced optical filter covering 310–500 nm ensures reliable ignition and flame supervision.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications – Fireye 85UVF1-1CEX-K3\u003c\/h2\u003e\u003cp\u003eKey parameters define its performance in harsh conditions:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpectral Range:\u003c\/strong\u003e 310–500 nm (advanced optical filter) – optimized for hydrocarbon flames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection:\u003c\/strong\u003e IP66 (NEMA 4X) – resists water and dust ingress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range:\u003c\/strong\u003e Ambient -40°F to 180°F; scanner internal -40°F to 150°F – suitable for extreme environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Relay:\u003c\/strong\u003e SPST (N.O.), 2A @ 30V DC or 2A @ 230V AC – direct control of burner safety circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalog Output:\u003c\/strong\u003e Isolated 4–20mA DC (max load 750Ω) – proportional flame signal for DCS\/PLC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAll specifications are directly from the Fireye 85UVF1-1CEX-K3 datasheet.\u003c\/p\u003e\u003ch2\u003eWhere the Fireye 85UVF1-1CEX-K3 Excels\u003c\/h2\u003e\u003cp\u003eCommon applications include industrial boilers, process heaters, and furnace burner management. The IP66 enclosure and wide temperature tolerance allow mounting directly on the windbox or combustion chamber. In dirty environments, the purge air requirement of 4 SCFM (up to 15 SCFM) keeps the optical path clean. The 4–20mA output enables trending and remote monitoring, reducing false trips and maintenance visits.\u003c\/p\u003e\u003ch2\u003eInstallation and Mounting Considerations\u003c\/h2\u003e\u003cp\u003eMount the Fireye 85UVF1-1CEX-K3 using the 8-pin quick-disconnect connector. Ensure a clean, dry, cool air supply for the purge – volume 4 SCFM at sufficient pressure to overcome furnace pressure. For heavy soot conditions, increase purge to 15 SCFM. The cast aluminum housing with gray powder coat provides corrosion resistance. Verify that the ambient temperature does not exceed 180°F internal or 150°F external during operation.\u003c\/p\u003e\u003ch2\u003eMinimizing Downtime Through Durable Design\u003c\/h2\u003e\u003cp\u003eThe Fireye 85UVF1-1CEX-K3's IP66 rating and robust construction reduce the need for frequent inspections. However, regularly check purge air flow and pressure; clogged filters can lead to false flame signals. The humidity tolerance of 95% non-condensing ensures operation in moist environments. With proper installation, this scanner delivers long service life, lowering total cost of ownership.\u003c\/p\u003e\u003ch2\u003eBuying the Fireye 85UVF1-1CEX-K3\u003c\/h2\u003e\u003cp\u003eBefore ordering, confirm your system's input voltage (24V DC nominal, 200 mA). The 8-pin connector must match your cable assembly. The Flame Relay is normally open; verify compatibility with your safety logic.
