Product Details

The Fireye UV1A12 is a compact non self‑check ultraviolet flame scanner belonging to the UV1A series. This UV scanner adopts a non‑replaceable quartz Geiger‑Müller UV tube to capture ultraviolet radiation from combustion flame and transmit pulse flame signals to matched Fireye flame safeguard amplifiers. As a reliable flame sensor, it comes with 12 feet TC‑ER tray rated cable and 1/2 inch NPT mounting thread, designed for safe industrial locations. This detector works perfectly for natural gas, propane and No.2 fuel oil burners and is stocked as genuine replacement spare part for boiler and combustion flame supervision.

Supported Functions

This ultraviolet flame detector senses UV emission generated by burner flame and sends valid flame signal to the paired flame safeguard control. When flame loss occurs, the flame signal disappears and triggers safety lockout and fuel shutoff. Without built‑in self‑check shutter, sensor integrity verification is completed by the host burner management system in each firing cycle.

Core Functions

The internal UV tube ionizes under flame ultraviolet radiation and generates pulse flame output. Its long tray rated cable suits long‑distance wiring inside boiler houses. The compact body fits narrow sight tube space, and it supports direct drop‑in substitution for existing UV1A12 scanners on compatible Fireye combustion systems.
