C7061A1046 | Honeywell | Ultraviolet Flame Detector

The C7061A1046 is a dynamic self-checking ultraviolet flame detector manufactured by Honeywell for industrial burner, boiler, and process heating systems. Operating on a 120 VAC supply, it senses the ultraviolet radiation emitted by gas, oil, or combination fuel flames, providing rapid signal response and continuous self-checking to prevent false flame indication in critical safety applications.

Dynamic Self-Checking Operation

The detector features a solid-state shutter mechanism that periodically interrupts the optical light path several times per minute to test the entire flame sensing circuit, including the UV sensing tube. If the detector fails to register the shutter interruption or senses a simulated flame condition during the check, the associated burner control logic initiates a safety shutdown.

Housing and Field Installation

Housed in a NEMA 4 explosion-proof cast aluminum enclosure, the module is rated for Class I, Groups C and D, as well as Class II, Groups E, F, and G hazardous location deployments. The unit mounts directly onto a 1-inch NPT sight pipe and includes a 1/2-14 NPSM conduit connection for field wiring.

Frequently Asked Questions

Q: How does the dynamic self-checking feature work on the Honeywell C7061A1046? A: An internal shutter periodically blocks the UV light path to test the electronic circuitry and UV tube, ensuring that any component failure triggers a safe system shutdown rather than a false flame signal.

Q: What mounting interface does the C7061A1046 flame detector use? A: The detector mounts directly onto a 1-inch NPT sight pipe directed toward the flame zone.

Q: What voltage is required to operate the Honeywell C7061A1046 detector? A: It operates on a standard 120 VAC supply at 50 or 60 Hz.
