Honeywell 113228/U UV Sensor for Burner

Honeywell 113228/U UV Sensor for Burner

The Honeywell 113228/U is a precision ultraviolet flame sensor engineered for seamless integration into industrial burner control architectures. Designed to operate within Honeywell’s proven combustion management ecosystem, this UV sensor serves as the critical detection layer between the physical flame and the control system’s safety logic — ensuring that burner ignition, flame presence, and shutdown sequences are executed with accuracy, speed, and reliability. In demanding industrial environments where combustion efficiency directly impacts energy consumption and operational safety, the 113228/U delivers consistent signal output that supports both real-time control and long-term system stability.

System Compatibility Notes

Within a layered combustion control architecture, the Honeywell 113228/U UV flame sensor does not operate in isolation — it is one node in a tightly coordinated system where every component must communicate reliably and respond predictably. At the control layer, the sensor interfaces directly with Honeywell burner control units such as the RM7800L or RM7840L flame safeguard controllers, which govern the complete ignition and shutdown sequence. The UV signal from the 113228/U is processed by a compatible flame amplifier module — such as the R7847A or R7849A amplifier card — which translates the raw UV detection into a logic-level input for the burner controller.

At the relay and interlock layer, the burner controller’s output connects to safety relay modules and solenoid valve drivers that control fuel flow. In integrated plant automation environments, the burner control unit may further communicate with a Honeywell HC900 hybrid controller or a third-party DCS via hardwired I/O or Modbus RTU, allowing the flame status to be monitored at the SCADA or HMI level. Operators using a Honeywell Experion PKS workstation or a panel-mounted HMI can view real-time flame status, burner cycle counts, and fault history without interrupting the combustion process.

On the power supply layer, the sensor and its associated control modules are typically fed through a dedicated 24 VDC or 120 VAC distribution rail, often protected by a Honeywell or third-party DIN-rail power supply module with surge protection to prevent nuisance trips caused by electrical noise from ignition transformers. Terminal blocks and shielded signal cables are used throughout the flame detection circuit to maintain signal integrity in high-EMI environments near large burners or induction heating equipment.

For redundant combustion systems — common in power generation boilers and large process heaters — dual UV sensors may be deployed in a cross-checking configuration, where two 113228/U sensors monitor the same flame from different angles, and the burner controller only confirms flame presence when both sensors agree. This redundancy architecture eliminates single-point detection failures and is a key requirement in many safety-instrumented system (SIS) designs aligned with IEC 61511 functional safety standards.

Industrial Application Notes

The Honeywell 113228/U UV flame sensor finds application across a broad range of industrial combustion processes. In power generation, it monitors pilot and main burner flames in gas- and oil-fired boilers, providing the flame safeguard controller with the detection signal needed to prevent unburned fuel accumulation and potential furnace explosions. In petrochemical and refinery environments, it is deployed on process heaters and fired reboilers where continuous flame monitoring is mandatory under process safety management (PSM) regulations.

In ceramic and glass manufacturing, the sensor monitors kiln burners operating at extreme temperatures, where reliable UV detection is preferred over infrared methods due to the high background radiation from hot refractory surfaces. In food and beverage processing, it supports direct-fired ovens and steam boilers, where burner reliability directly affects production throughput and energy efficiency. In district heating and building HVAC systems, the 113228/U is integrated into commercial boiler control panels to ensure safe and efficient combustion across variable load conditions.

Across all these applications, the sensor contributes to reduced fuel waste, lower maintenance intervention frequency, and improved equipment utilization rates — all of which translate directly into measurable operational stability and lower total cost of ownership over the system’s operational life.

Product Compatibility FAQ

Q1: Is the Honeywell 113228/U compatible with existing Honeywell RM7800 series burner controllers?
Yes. The 113228/U is designed to work with Honeywell’s RM7800 series flame safeguard controllers when paired with a compatible flame amplifier module such as the R7847A or R7849A. Always verify the amplifier model’s UV sensor compatibility in the controller’s wiring diagram before installation.

Q2: Can this sensor be integrated into a PLC or DCS-based control architecture?
The 113228/U outputs a hardwired flame presence signal through the burner controller’s relay contacts, which can be wired as a digital input to any PLC or DCS I/O module. system integration with higher-level control systems is achieved through the burner controller’s interlock and status outputs, not directly from the sensor itself.

Q3: What does the warranty terms confirmed during quotation cover, and how is the sensor tested before shipment?
Every Honeywell 113228/U supplied by ZYPLC carries a warranty terms confirmed during quotation covering manufacturing defects and functional performance. Each unit undergoes pre-shipment functional verification to confirm UV detection response and electrical integrity. In the event of a warranty claim, ZYPLC provides replacement or repair support with documented test records available upon request.
