Monitoring hydrocarbon flames in heavy-duty gas turbine environments is the primary function of the Honeywell LG1093AA46 ultraviolet (UV) flame sensor. This industrial-grade Geiger-Mueller type sensor phototube detects radiation specifically in the 180 to 260 nm spectrum, rendering it completely solar-blind and highly tolerant to black-body radiation. Engineered for compatibility with EG1033 amplifier modules, this sensor serves as a critical safety component on General Electric and GE-licensee gas turbines. The assembly features a robust viewing window rated for high pressure and is equipped with an integrated, Teflon-shielded cable to withstand extreme thermal and mechanical stresses in power generation and compressor applications.

| OEM Cross Reference | GE 261A1812P15 |
| Reliability Profile | 10,000 hours MTBF; 2-year shelf-life |

The LG1093AA46 is physically and electrically interchangeable with standard GE part number 261A1812P15. It must be paired with Honeywell EG1033 series controller modules to process the phototube output. Note that this standard UV sensor is not compatible with GE/NP DLE (Dry Low-NOx) gas turbines. DLE turbines produce different flame emission signatures and require pre-selected, specialized UV sensors not available under standard Honeywell commercial designations.
The internal Geiger-Mueller tube will degrade rapidly if operated continuously above its maximum limit of 176 degC. In high-ambient compartments, proper cooling air or isolation mounts should be implemented to protect the internal optics. Additionally, because oil mist, soot, and heavy moisture absorb UV light in the 180 to 260 nm band, even minor window contamination can severely decrease sensitivity, resulting in false flame-out alarms despite an active combustion profile. Periodic inspection of the 10-bar rated optical window is critical.
The sensor's integral Teflon-shielded cable must be routed through dedicated, grounded metal conduit. Avoid running the high-sensitivity signal cable adjacent to high-voltage ignition transformer leads or heavy motor power lines to prevent EMI-induced false flame indications. Ensure the cable shield is tied directly to the designated instrument ground at the EG1033 amplifier side only; do not ground the shield at both ends to prevent ground loops.
CRITICAL WARNING
De-energize the entire turbine ignition and control system before starting installation. This device is installed in potentially explosive environments. Ensure all conduit seals are properly poured and certified explosive-proof threads are fully engaged to maintain ATEX/FM safety compliance.
Inspect the 3/4-inch internal NPT mounting thread on the turbine casing or sight pipe. Ensure it is clean, free of carbon deposits, and correctly aligned with the primary flame zone.
Verify that the sensor's quartz viewing window is completely clean. Use an approved industrial optical solvent if grease or particulate matter is present.
Thread the sensor onto the mounting pipe. Apply a high-temperature, anti-seize compound strictly to the external threads of the mounting pipe, ensuring no material contacts the viewing window.
Connect the 1-inch external conduit thread to the flexible protection conduit. Route the 61-foot Teflon-shielded cable to the junction box or cabinet housing the EG1033 amplifier module.
