Product Details

The Fireye UV1AL-6 is a non-self-check ultraviolet flame scanner belonging to the UV1AL series, fitted with a 6 ft TC‑ER rated integrated cable compliant with UL 1569 standard. This ultraviolet flame scanner detects UV radiation emitted during combustion and transmits reliable flame presence and flame loss signals to Fireye burner safeguard controllers. As a dependable burner UV detector, it adopts a 1/2 inch NPT threaded coupling for direct sight pipe mounting and can withstand furnace pressure up to 1 PSI without extra sealing accessories; a quartz window coupling is available for high positive pressure applications. This Fireye UV1AL sensor is stocked as genuine replacement spare part, widely used for gas and light oil burners equipped with BurnerPRO, MBCE and NXF4000 burner management systems.

Supported Functions

This ultraviolet flame scanner continuously captures UV radiation generated by stable combustion. The burner UV detector converts optical flame signals into valid electrical feedback for the flame safeguard unit. It sends flame-loss alarm once combustion disappears to trigger fuel shutoff and burner lockout sequence. This Fireye UV1AL sensor supports continuous long-term monitoring for steady and intermittent industrial burners.

Core Functions

High-sensitivity UV sensing tube distinguishes genuine flame ultraviolet signals and suppresses false alarms from hot refractory surfaces. The ultraviolet flame scanner features robust crush and impact resistant cable suitable for exposed tray routing. Its threaded sight pipe design ensures reliable sealing and convenient alignment adjustment. Standard electrical definition enables drop-in substitution for a faulty UV1AL-6 without heavy rewiring modification.
