Fireye UV7R4 Scanner

The Fireye UV7R4 Flame Scanner is a high-sensitivity, non-self-checking ultraviolet flame detector engineered for industrial applications requires a 90-degree right angle orientation. This specific configuration is essential for space-constrained burner fronts where a straight-line line-of-sight is physically impossible. Utilizing a gas-filled quartz UV tube, the UV7R4 responds exclusively to the 250 to 400 nanometer radiation range, ensuring it ignores the infrared radiation produced by hot refractory. The unit is optimized for gas and oil-fired burners and integrates seamlessly with Flame-Monitor and MicroM flame safeguard controls. With a 1/2" NPT mounting connection and 72-inch unshielded lead wires, this scanner provides a reliable signal to the amplifier, maintaining the flame relay for intermittent light-off sequences and continuous monitoring in demanding process heating environments.

• Compact 90° Form Factor: Simplifies installation in tight mechanical rooms where standard straight scanners interfere with piping or electrical conduit.
• High-Sensitivity Detection: Engineered to monitor frequencies specific to ultraviolet radiation, preventing false flame signals from background heat.
• Industrial Build Quality: UL listed and FM approved for use in power generation systems, industrial boilers, and commercial heating plants.
• Reverse Connection Protection: Integrated circuitry safeguards the detector tube and amplifier against improper field wiring.
• Robust Cyclic Performance: Designed to handle the rigors of frequent cycling in gas and oil burners without signal degradation.

Is the Fireye UV7R4 a self-checking scanner?
No, the UV7R4 is a non-self-checking UV scanner. It is designed for use on burners that cycle at least once every 24 hours to allow the flame safeguard to verify clean sensor operation.

Can I use this scanner with a straight-on viewing port?
This model is specifically a right-angle UV scanner. If your installation requires a straight line of sight, you should specify the UV1A series or similar straight-mount equivalents.

What is the maximum ambient temperature for the UV7R4?
The scanner is rated for operation up to 200°F (93°C). Ensure proper insulation or cooling if mounting in high-heat zones to prevent damage to the internal ultraviolet tube.
