Product Details

The Fireye UV1A6 is a compact non-self-check miniature ultraviolet flame scanner belonging to the UV1A family, fitted with an integrated 6 ft TC‑ER tray exposed run cable. This miniature ultraviolet flame scanner uses a sealed non-replaceable gas-filled quartz UV tube to detect ultraviolet radiation released by combustion flame and transmits pulse flame signals back to Fireye M-series and BurnerPRO flame safeguard amplifiers. As a reliable burner UV detector, it features a 1/2 inch NPT threaded fitting for direct sight pipe mounting and is designed for tight installation space on packaged burners, boilers and process heaters. This Fireye UV1A flame sensor is stocked as original replacement spare part, suitable for natural gas, propane and No.2 light fuel oil combustion monitoring.

Supported Functions

This miniature ultraviolet flame scanner continuously captures UV energy generated by steady or cyclic combustion. The burner UV detector converts optical UV radiation into pulse electrical signals to indicate flame presence. When flame loss occurs, it stops generating pulse signals and triggers the fuel shutoff and burner lockout sequence of the safeguard system. This Fireye UV1A flame sensor supports continuous long-time operation under normal industrial combustion conditions.

Core Functions

The miniature UV sensing tube selectively responds to flame ultraviolet rays and minimizes false alarms caused by hot refractory surfaces. The miniature ultraviolet flame scanner’s compact body is well suited for burners with limited sighting access. Its integrated cable and standard thread simplify field alignment and installation. Standard electrical definition allows drop‑in substitution for a faulty UV1A6 without heavy rewiring modification.
