Fireye UV1A3 UV Scanner

The Fireye UV1A3 UV Scanner is a non-self-checking ultraviolet flame detector specifically engineered for integration with Flame-Monitor, MicroM, and BurnerLogix flame safeguard controls. This industrial-grade sensor utilizes a UV tube sensitive to radiation in the 185 to 245 nanometer range, making it ideal for detecting flames from gas and light oil fuels while ignoring refractory infrared interference. Designed for high-duty cycle applications, the UV1A3 features a standard 1/2" NPT mounting collar and 36-inch shielded leads to mitigate electrical noise and ensure signal integrity in complex boiler rooms. With an operating temperature range of -40??F to 200??F and a maximum operating voltage of 560 VAC, this flame sensor provides the rugged reliability required for commercial burner systems and industrial process heating equipment. Its compact design allows for precise line-of-sight positioning to capture the first one-third of the flame envelope for optimal signal strength.

Key Benefits for Technicians

• Universal Mounting: The 1/2" NPT collar simplifies installation on standard burner sight pipes and observation ports.
• EMI Protection: Factory-installed 36-inch shielded leads prevent false flame signals caused by nearby high-voltage ignition transformers or VFDs.
• Extreme Durability: Rated for non-condensing humidity up to 85%, ensuring long-term performance in demanding mechanical rooms.
• Optimized Sensing: Specifically tuned for UV flame detection, preventing false "flame on" indications from hot furnace walls or refractory.
• Control Compatibility: Engineered to work seamlessly with Fireye burner management systems for fast safety shutdowns and accurate combustion monitoring.

Common Questions

Can the UV1A3 leads be extended in the field?
Yes, leads can be extended using suitable shielded wire; however, it is critical to maintain proper grounding of the shield to prevent electrical interference from disrupting the flame signal to the control module.

How often should the UV1A3 scanner be cleaned?
The quartz lens should be inspected and cleaned regularly with a soft, lint-free cloth. In high-dust environments, we recommend using a 1/2" NPT air purge or "y" tap to keep the line of sight clear and the sensor cool.

Is this scanner compatible with self-checking flame safeguards?
No, the Fireye UV1A3 is a non-self-checking sensor. For applications requiring continuous burning (24 hours or more), you must use a self-checking scanner like the 45UV5 or 55UV5 series to meet safety codes.
