Honeywell C7027A1031 Flame Detector

Upgrade your burner safety protocols with the Honeywell C7027A1031 Minipeeper, a compact ultraviolet flame detector engineered for industrial and commercial combustion environments. This sensor is specifically designed for flame supervision in gas-fired burners, as well as oil and coal applications, where secondary radiation or hot refractory surfaces might cause false signals with standard infrared sensors. The C7027A1031—which is identical to the C7027A1031/U—utilizes a specialized UV sensing tube to detect the specific ultraviolet radiation emitted by combustion flames, ensuring rapid response to flame failure while ignoring background infrared heat.

Built for the rigors of the mechanical room, this Honeywell flame sensor features a wide ambient temperature rating of -40°F to 215°F, making it suitable for both cold starts and high-heat proximity. It mounts directly onto a 1/2-inch sighting pipe via an integral collar, allowing for streamlined integration into existing boiler or furnace hardware. With a generous 96-inch lead length (8 feet) of NEC Class 1 leadwires, technicians have the necessary slack for secure routing to Honeywell Flame Safeguard primary safety controls and ultraviolet flame amplifiers like the R7849 series. When properly installed, this unit maintains a pressure seal up to 5 psi, providing reliable performance in pressurized blast tube applications.

• Versatile Fuel Compatibility: Engineered for reliable detection in coal, gas, and oil-fired burners.
• Compact Form Factor: The "Minipeeper" design allows for easy mounting in tight spaces or direct blast tube installation.
• Parallel Wiring Capability: Multiple C7027A1031 units can be wired in parallel to improve flame detection reliability in difficult sighting applications.
• Rugged Environmental Resilience: Sustains consistent operation in ambient temperatures ranging from -40°F to 215°F.
• Standardized Integration: Uses a 1/2-inch integral collar for mounting on standard NPT sighting pipes.

What is the difference between the C7027A1031 and the C7027A1031/U?
These models are technically identical; the "/U" suffix simply denotes a "Universal" packaging designation used by the manufacturer, ensuring the same specifications and compatibility.

Can this sensor be used in high-pressure burner applications?
Yes, when installed correctly according to the manufacturer’s instructions, the sensor is rated to seal against pressures up to 5 psi (34.5 kPa).

Which safety controls are compatible with the C7027A1031?
This detector is designed to work with various Honeywell Flame Safeguard controls, including the RM7800 series and R7249, R7290, R7749, and R7849 ultraviolet amplifiers.
