Product Details

The Fireye UV90-6 is a non self‑check ultraviolet flame scanner from Fireye UV90 series, equipped with 6 feet flexible conduit and snug‑fit mounting block for frontal or 90‑degree side viewing. This UV scanner captures ultraviolet radiation generated by combustion flame and transmits flame signal to matched Fireye flame safeguard amplifiers for continuous flame supervision. As a reliable flame detector, it suits natural gas, propane and light fuel oil burners and serves as a popular replacement spare for legacy boiler and combustion control systems. This Fireye UV sensor is stocked as genuine replacement spare part for industrial burner flame monitoring.

Supported Functions

This UV flame detector senses UV radiation emitted by burner flame and sends valid flame signal to the flame amplifier. When the flame extinguishes, it stops outputting flame signal and triggers safety lockout and fuel shutoff through the paired burner management chassis. This UV scanner delivers stable continuous flame monitoring during regular combustion operation.

Core Functions

The built‑in quartz UV tube ionizes under flame ultraviolet radiation and produces pulse flame signal. Its side viewing design facilitates installation when direct line of sight is limited. The snug‑fit mounting block removes the need for threaded sight pipe and helps prevent leakage and misalignment. It supports drop‑in substitution for existing UV90‑6 scanners on compatible combustion systems.
