Product Details

The Fireye UV90-9 is a non self‑check ultraviolet flame scanner from Fireye UV90 series, fitted with 9 feet flexible conduit and snug‑fit mounting block for frontal or 90‑degree lateral installation. This UV scanner captures ultraviolet radiation generated during combustion and transmits flame signal to matched Fireye flame safeguard amplifiers for continuous flame monitoring. As a reliable flame detector, it works well for natural gas, propane and light fuel oil burners and is widely adopted as replacement spare for legacy boiler and combustion control systems. This Fireye UV sensor is stocked as genuine replacement spare part for industrial burner flame supervision.

Supported Functions

This UV flame detector senses UV radiation from the burner flame and sends valid flame signal to the flame amplifier. If the flame extinguishes, it stops generating UV signal and triggers safety lockout and fuel shutoff via the paired burner management chassis. This UV scanner provides stable continuous flame monitoring for routine combustion operation.

Core Functions

The quartz UV tube ionizes under flame ultraviolet radiation to produce pulse flame signal. Its special side viewing design makes installation easier when direct line of sight is limited. The snug‑fit mounting block removes requirement for threaded sight pipe and helps prevent leakage and misalignment. It supports drop‑in substitution for existing UV90‑9 scanners on compatible combustion systems.
