Product Details

The Fireye UV1A-1-CEX is a miniature non self‑check ultraviolet flame scanner from UV1A series, fitted inside an ATEX explosion‑proof housing for hazardous location installation. This UV scanner adopts a non‑replaceable quartz Geiger‑Müller tube to capture ultraviolet radiation from combustion flame and transmits pulse flame signals to compatible Fireye flame safeguard controllers. As a reliable flame sensor, it features short captive cable and two‑wire polarity‑free wiring layout, suitable for natural gas, propane and No.2 fuel oil burners. This Ex detector is widely used in refineries, sulfur recovery units and other classified hazardous zones and stocked as genuine replacement spare part for industrial 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. If the flame extinguishes, flame signal vanishes and triggers safety lockout and fuel shutoff. Without built‑in self‑check shutter, sensor integrity verification is handled by the host burner management system during each firing cycle.

Core Functions

The internal UV tube ionizes under flame ultraviolet radiation and generates pulse flame output. Its cast aluminum explosion‑proof enclosure prevents ignition of surrounding flammable gas mixtures. The compact form fits tight sight tube spaces and supports direct drop‑in substitution for existing UV1A‑1‑CEX installations.
