Honeywell C7027A1023 Flame Detector

The Honeywell C7027A1023 Minipeeper Ultraviolet Flame Detector is a compact, high-performance ultraviolet sensor essential for monitoring coal, gas, and oil-fired burners. Engineered for Honeywell Flame Safeguard primary safety controls, this detector facilitates reliable flame detection by sensing ultraviolet radiation in the combustion chamber. The C7027A1023, also identified by part number 8026145, features a 96-inch lead length to accommodate complex wire routing and blast tube mounting. Designed for durability in industrial environments, it operates effectively within an ambient temperature range of 0°F to 215°F. The unit mounts securely onto a 1/2-inch sighting pipe via an integral collar and is rated to seal against pressures up to 5 psi when correctly installed. This UV flame sensor is precision-tuned to detect the UV spectrum while remaining unresponsive to interior furnace radiation or hot refractory surfaces, preventing false flame signals during operation.

Key Benefits for Technicians:

• Universal Compatibility: Seamlessly integrates with Honeywell R7247, R7248, R7847, and other standard ultraviolet flame amplifiers.
• Rugged Sealing: Rated for pressures up to 5 psi, ensuring combustion safety control integrity in pressurized burner housings.
• Compact Form Factor: Small footprint allows for installation in tight spaces where larger scanners cannot fit.
• High Temperature Resistance: Sustains performance in extreme conditions up to 215°F without premature sensor degradation.
• Simplified Retrofitting: The 1/2-inch NPT mounting collar and 8-foot lead wires streamline HVACR flame detector replacement in the field.

Common Questions & Technical Support:

How do I test the Honeywell C7027A1023 for proper operation?
Technicians should measure the flame signal voltage using a volt-ohm meter at the flame safeguard control's test jack. Ensure the sighting pipe is clear and the sensor is properly aligned with the lead of the flame.

Can the Minipeeper detect a flame through a glass window?
No. Standard glass blocks ultraviolet radiation. This ultraviolet flame detector requires a clear line of sight to the flame or a quartz glass window to function correctly.

What causes a weak signal in UV flame sensors?
Common issues include a dirty sensor lens, incorrect sighting pipe alignment, or soot buildup. Regular maintenance involves cleaning the quartz lens with a damp, lint-free cloth to maintain signal strength.
