Overview
The Honeywell C7027A1023 is a compact ultraviolet (UV) flame sensor designed for burner management and flame supervision in commercial and industrial combustion applications. This sensor detects ultraviolet radiations emitted by combustion flames and is used with Honeywell burner controls to provide flame supervision for commercial and industrial burner applications.
Key Features
- UV Detection Technology: Compact analogue UV flame sensor to detect ultraviolet radiations emitted by combustion flames
- Minipeeper Design: Rugged, compact, with encapsulated sensing tube for maximum protection
- Parallel Wiring: Detectors can be wired in parallel for difficult sighting applications
- Sealed Against Pressure: Seals against pressures up to 5 PSI (34.5kPa) when correctly installed
- Compact Mounting: Allows for blast tube mounting due to compact size
- Multi-Fuel Capability: For use with coal fired burners, gas fired burners, and oil fired burners
