Product Details

The Fireye UV1ALCEX, also marked UV1AL‑CEX, is a non self‑check ultraviolet flame scanner built upon the UV1AL core and fitted inside an ATEX Exd IIC T6 certified explosion‑proof housing for hazardous locations. This UV scanner captures ultraviolet radiation from combustion flame and delivers pulse flame signals to Fireye BurnerPRO, MBCE and NXF4000 flame safeguard controls. As a reliable flame sensor, it adopts a two‑wire non‑polarity wiring scheme and supports optional quartz window coupling for high furnace pressure service. This Ex detector is widely selected for gas‑fired burners in petrochemical and other explosive atmosphere zones and is stocked as genuine replacement spare part for hazardous‑area combustion flame supervision.

Basic Parameters

Brand: Fireye

Model: UV1ALCEX (UV1AL‑CEX)

Type: Non self‑check UV flame scanner, ATEX hazardous location

Sensor: UV Geiger‑Müller tube

Certification: Exd IIC T6 ATEX

Mount thread: 1/2" NPT

Wiring: 2‑wire, no polarity requirement

Compatible control: BurnerPRO, MBCE, NXF4000 series

Supported fuels: Natural gas, propane

Product type: Original Fireye explosion‑proof flame scanner spare sensor

Supported Functions

This ultraviolet flame detector senses UV emission generated by burner flame and sends valid flame signal to the paired flame safeguard control. Once flame loss occurs, the signal terminates and triggers safety lockout and fuel shutoff. Without internal self‑check shutter, sensor integrity verification depends on the host burner control during each firing cycle.

Core Functions

The UV tube generates pulse output under flame ultraviolet exposure. Its explosion‑proof housing prevents ignition of surrounding flammable gas mixtures. The simple two‑wire connection simplifies retrofit, and it can serve as a drop‑in replacement where UV1ALCEX is the approved hazardous‑zone scanner.
