Product Details

The Fireye UV2 is a classic non self‑check ultraviolet flame scanner for Fireye M‑Series flame safeguard systems. This UV scanner uses Geiger‑Müller UV tube to pick up ultraviolet radiation from combustion flame and sends pulse flame signals to matched MAUV series amplifiers. As a reliable flame sensor, it is equipped with 36 inch shielded lead, 3/8 inch NPT purge port and standard sight fitting, widely used as replacement spare for older boilers and process heaters burning gas, light oil and waste fuel gas. This detector is stocked as genuine legacy spare part for industrial burner flame supervision.

Supported Functions

This ultraviolet flame detector senses UV emission from burner flame and transmits valid flame signal to the paired M‑Series UV amplifier. If flame extinguishes, signal disappears and triggers safety lockout and fuel shutoff. Since it has no built‑in self‑check shutter, system integrity check relies on burner cycling and amplifier diagnostics.

Core Functions

The UV tube generates pulse output when exposed to flame ultraviolet light. The purge air connection keeps the lens clean from soot and combustion debris. Its simple two‑wire connection has no polarity requirement and supports direct drop‑in substitution for existing UV2 scanners on compatible Fireye M‑Series controls.
