Product Details
The Honeywell C7061A1046, also cataloged as the C7061A1046 Ultraviolet Flame Detector, operates as a dedicated hardware component for continuous optical flame sensing and burner safety monitoring within industrial combustion platforms. Operating on 120 VAC line power, it senses ultraviolet radiation emitted by gas, oil, or combination fuel flames to execute physical flame-on/flame-off signal transmission to the primary burner management system controller.

Channel-to-Channel Isolation & DCS Process Telemetry
The C7061A1046 features a self-checking mechanical shutter mechanism that periodically interrupts incoming ultraviolet radiation to validate sensor tube integrity and prevent un-safe false-flame indication. High internal electrical isolation decouples line-voltage shutter drive circuits from low-voltage signal outputs connected to main DCS flame safeguard modules. This isolation barrier prevents power-line transients and electrical noise from corrupting co-located 4-20 mA HART loop protocol flame intensity signals or digital safety interlock loops across the combustion control network.
Frequently Asked Questions
Q: What is the purpose of the oscillating mechanical shutter inside the C7061A1046 detector?
A: The shutter cycles periodically to block UV light from reaching the sensor tube, providing a dynamic self-checking routine that detects internal tube failure or continuous discharge, thereby enforcing a fail-safe state.
Q: How is the physical mounting interface specified for the sight pipe installation?
A: The unit features an integrated 1 inch NPT internal thread mount designed to screw directly onto a standard 1 inch NPT sight pipe angled toward the primary flame envelope.
Q: Can the C7061A1046 be installed in wet or outdoor process locations?
A: Yes, the heavy-duty enclosure carries a NEMA 4 (IP66) rating, which protects internal optical components and wiring terminals against windblown dust, rain, and direct water jets.
Field Installation Guidelines
- Thread the C7061A1046 housing onto a 1 inch NPT sight pipe, engaging a minimum of 5 NPT threads to form a rigid, gas-tight mechanical seal.
- Align the sight pipe toward the intersection of the primary burner flame zone to optimize ultraviolet radiation reception.
- Wire the 120 VAC main supply and flame signal lines to internal screw terminals using shielded, high-temperature copper conductors.
- Ensure the NEMA 4 enclosure cover is fully tightened and conduit entries are sealed with liquid-tight fittings to block moisture ingress.
