UV1A3 Fireye Scanner

Overview

The Fireye UV1A3 is a compact, non-self-checking ultraviolet flame scanner designed for industrial and commercial burner applications. It detects UV radiation emitted by flames from fossil fuels such as natural gas, propane, and light oil. This miniature detector features a gas-filled quartz UV tube and is engineered for use with Fireye flame safeguard and burner management systems, providing high-speed response to flame presence or failure.

Features

• High-sensitivity quartz UV tube for detecting ultraviolet radiation in oil and gas flames.
• Compact design with a 1/2 inch NPT mounting collar for simplified installation.
• Integrated 3-foot (900mm) flexible conduit meeting UL-1569 crush and impact standards.
• Wide system compatibility with Fireye M-Series, MicroM, Flame-Monitor, BurnerLogix, and Nexus controls.
• Durable, sealed construction designed for harsh industrial environments and NEMA 4X compliance.
• Low maintenance requirements with a focus on periodic lens cleaning rather than internal replacement.

Specifications

• Mounting: 1/2 inch NPT threaded collar.
• Cable: 3 feet (915 mm) of shielded flexible conduit.
• Operating Voltage: 560 VAC (supplied from the control/amplifier).
• Temperature Range: -40 degrees F to 200 degrees F (-40 degrees C to 94 degrees C).
• Humidity: 85 percent RH maximum, non-condensing.
• Dimensions: 1.06 in. diameter x 2.53 in. length.
• Approvals: UL Listed (cULus) and FM Approved.
• Tube Type: Non-self-checking gas-filled quartz.

Applications

The UV1A3 is ideally suited for monitoring flames in industrial and commercial boilers, furnaces, process heaters, and HVAC systems. Because it is non-self-checking, it is intended for use in “cycling” burner applications where the burner is shut down at least once every 24 hours to allow for a safety check of the scanner. It is compatible with burners firing natural gas, propane, or No. 2 light oil.
