Honeywell C7076A1015 – Self-Check UV Flame Sensor | Burner Management Systems
Engineering Background
The Honeywell C7076A1015 is a self-checking ultraviolet (UV) flame sensor engineered for continuous-duty industrial burner management applications. Designed to operate within Honeywell’s proven flame safeguard ecosystem, this sensor provides reliable, fail-safe flame detection by monitoring UV radiation emitted during combustion. The self-check architecture ensures that any internal sensor failure is automatically detected and reported, preventing dangerous false-safe conditions in critical thermal processes.
Product Positioning
The C7076A1015 is the preferred choice for process engineers and OEM integrators specifying UV flame detection in boilers, industrial furnaces, process heaters, and multi-burner combustion systems. Its compatibility with Honeywell R7847, R7849, and RM7800-series flame amplifiers makes it a drop-in solution for both new installations and legacy system upgrades. Konmask.com supplies this sensor as a genuine, traceable component with full quality documentation.

Proven Application Environments
- Industrial Boilers – Steam and hot-water boilers requiring continuous flame supervision with automatic self-diagnostics
- Process Furnaces & Kilns – High-temperature combustion chambers where UV detection outperforms infrared in sooty or luminous-flame conditions
- Multi-Burner Combustion Systems – Parallel burner arrays managed by RM7800-series programmable controllers
- Thermal Oxidizers & Incinerators – Waste-gas combustion systems requiring fail-safe flame proof
- Power Generation Auxiliary Burners – Startup and pilot burner supervision in gas turbine and combined-cycle plants
- OEM Packaged Burner Units – Factory-integrated into Honeywell-compatible burner management panels
Engineering Advantages
- Self-Check Architecture – Continuously verifies sensor tube integrity; any degradation triggers immediate lockout signal, eliminating dangerous false-safe states
- UV-Only Detection – Immune to infrared background radiation from hot refractory walls, reducing nuisance trips in high-temperature environments
- Wide Viewing Angle (70°) – Accommodates burner misalignment and simplifies sight-pipe positioning during commissioning
- NEMA 4 / IP65 Enclosure – Suitable for washdown environments and outdoor installations subject to moisture ingress
- Direct Amplifier Compatibility – Plug-compatible with the full Honeywell R7847/R7849/RM7800 amplifier family; no signal conditioning required
- Long Service Life – UV tube rated for extended duty cycles; self-check function provides early warning before end-of-life failure
System Architecture & Signal Flow
The C7076A1015 operates as the sensing element within a Honeywell flame safeguard loop. UV photons from the burner flame strike the sensor’s internal UV tube, generating a pulsed signal proportional to flame intensity. This signal is transmitted to a compatible flame amplifier (e.g., R7847A), which processes the pulse rate and amplitude to determine flame presence. The self-check circuit periodically interrupts the UV tube bias voltage; if the tube fails to respond correctly, the amplifier drives the burner controller to a safe lockout state. The entire detection-to-lockout sequence complies with IEC 61511 SIL 2 functional safety requirements when integrated with a certified RM7800-series controller.

Technical FAQ
Q: Can the C7076A1015 detect natural gas flames?
A: Yes. Natural gas flames emit sufficient UV radiation in the 185–260 nm band for reliable detection. The sensor is equally effective on oil, propane, and hydrogen flames.
Q: What is the difference between C7076A1015 and C7076D?
A: The C7076A series uses a self-checking UV tube design compatible with R7847/R7849 amplifiers. The C7076D is a non-self-checking variant. Always match the sensor to the amplifier’s self-check input requirements.
Q: How often should the UV tube be replaced?
A: Honeywell recommends annual inspection. The self-check function provides continuous in-service monitoring; a lockout event with no combustion fault present is a reliable indicator of tube end-of-life.
Q: Is the C7076A1015 suitable for outdoor installation?
A: Yes. The NEMA 4 enclosure rating provides protection against rain, splashing water, and windblown dust, making it suitable for outdoor boiler houses and process heater installations.
Q: Can Konmask provide a Certificate of Conformance?
A: Yes. CoC documentation is available for all shipments upon request. Contact support@konmask.com with your order number.
