Product Details

The Fireye UV1A50 is a compact non self‑check ultraviolet flame scanner from the UV1A series, the standard non‑explosion‑proof version of UV1A50EX. This UV scanner uses a quartz Geiger‑Müller tube to capture ultraviolet radiation produced by combustion flame and sends pulse flame signals to compatible Fireye flame safeguard controllers. As a reliable flame sensor, it adopts two‑wire polarity‑free wiring and compact lightweight construction for indoor and safe industrial locations. This detector is widely used for gas and No.2 oil burners and stocked as genuine replacement spare part for boiler flame supervision.

Supported Functions

This ultraviolet flame detector senses UV light emitted by burner flame and transmits valid flame signal to the paired flame safeguard control. Once flame loss occurs, the flame signal disappears and triggers safety lockout and fuel shutoff. Without built‑in self‑check shutter, sensor integrity check 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 small size enables installation in limited sight tube space. The simple two‑wire connection simplifies field wiring and retrofit. It serves as direct drop‑in replacement for existing UV1A50 scanners on matching combustion systems.
