Description

Engineered for heavy-duty gas turbine combustion monitoring, the Honeywell LG1093AA44 is an industrial ultraviolet (UV) flame sensor optimized for power generation and compressor applications. Utilizing a specialized Geiger-Mueller type sensor phototube, this unit is designed to detect the UV radiation emitted by hydrocarbon flames while remaining completely solar-blind and highly tolerant to black-body radiation. Proven over decades of deployment on General Electric and GE-licensee gas turbines, this sensor interfaces seamlessly with EG1033 series amplifiers to provide critical flame status feedback to your turbine control system.

Features

Highly Sensitive Phototube: Specifically tuned to target the 180 to 260 nm UV spectrum for reliable flame detection.
Solar Blind Design: Prevents false positive readings from sunlight, infrared emissions, or surrounding high-temperature black-body radiation.
Integrated Shielded Cable: Includes a 16-foot (4.9 m) Teflon-shielded cable with a 1-inch external conduit thread for structural protection in harsh environments.
Pressure-Resistant Optics: Built-in optical viewing window rated for system pressures up to 10 bar (150 psi).
Explosive Atmosphere Approvals: Certified for Zone 1 and Zone 2 environments (ATEX EEx d IIC T3) and Class I, Division 1 and 2 hazard areas.

Applications

General Electric (GE) and GE-licensee industrial gas turbines.
Turbine-driven compressor stations in gas pipeline transmission.
Utility-scale power generation combustion monitoring systems.
Hazardous-area industrial burners and combustion processes.

Empirical Engineering Insights

Alternative Models & Compatibility

The LG1093AA44 is designed exclusively to interface with Honeywell EG1033 amplifier modules. It is highly recommended to verify whether your specific turbine control application requires the transistor open-collector output of the EG1033AA or the SPDT relay contacts of the EG1033AB/AC units, as the sensor's baseline signal output is passive and requires active amplification to integrate with your PLCs or safety instrumented systems.

Application Pitfalls & Engineering Notes

CRITICAL APPLICATION EXCLUSION: The standard Honeywell LG1093 series, including this LG1093AA44 model, will not reliably operate on Dry Low NOx (DLE) gas turbines (such as GE/NP DLE configurations). DLE turbines require specialized, pre-selected sensors with alternative spectral thresholds. Attempting to use a standard LG1093 sensor in DLE environments will lead to frequent flame-out false alarms and operational instability.

Commissioning & Wiring Tips

When routing the integrated 16-foot Teflon-shielded cable, always run the conduit separate from high-voltage motor starters, ignition cables, or high-frequency variable speed drives (VSDs). Electromagnetic coupling on the sensor signal line can distort the high-impedance pulse signals generated by the Geiger-Mueller phototube, resulting in false flame-present signals during startup phases.

Installation Guidelines

CRITICAL WARNING: HIGH-VOLTAGE & SYSTEM COUPLING

Before removing or replacing an existing flame sensor, verify that the turbine is fully shutdown and de-energized. High voltages are present on the sensor lines when connected to active EG1033 amplifiers. Ensure the mounting sight pipe has cooled completely and that system pressure is depressurized below 10 bar before extraction.

Inspect the optical viewing window on the LG1093AA44 for physical scratches, oil film, or debris. Clean only with optical-grade solvent if necessary.

Apply high-temperature, anti-seize compound to the 3/4 inch NPT threads. Screw the sensor securely into the mounting port on the turbine casing, ensuring a gas-tight seal.

Route the 16-foot Teflon integrated cable through a continuous 1-inch rigid or flexible conduit. Connect the shield line to the dedicated instrumentation ground terminal inside the local junction box.

Can the LG1093AA44 sensor be deployed on Dry Low NOx (DLE) gas turbines?

No. The standard LG1093AA44 is not compatible with DLE turbines due to alternative combustion physics. It will result in false alarms and unstable performance. DLE applications require pre-selected OEM parts.

What is the maximum cable distance allowed from the sensor to the EG1033 amplifier?

The maximum recommended distance between the Honeywell LG1093AA44 sensor and its matched EG1033 amplifier is 330 meters (1000 feet).

Is the integrated cable on the LG1093AA44 replaceable in the field?

No. The 16-foot Teflon-shielded cable is sealed into the sensor body at the factory to maintain the physical pressure seal and environmental ingress ratings.

What spectral range is this Honeywell phototube sensitive to?

The sensor uses a Geiger-Mueller tube that is highly sensitive to ultraviolet (UV) radiation in the 180 to 260 nm range, ensuring it remains blind to sunlight and black-body heat.
