Honeywell LG1093AC01 Gas Turbine LG Flame Detector

Description

The Honeywell LG1093AC01 is a ultraviolet (UV) radiation flame detector engineered for gas turbine flame monitoring systems. The unit senses the UV radiation emitted by a hydrocarbon flame and transmits a high-speed signal to indicate a flame or no-flame condition. Utilizing a Geiger Mueller-type phototube sensor, the detector is solar blind and tolerant to black body radiation. It is widely applied across General Electric and GE licensee gas turbines for power generation and compressor operations, delivering high sensitivity with typical response times of 0.1 seconds for flame presence.

Features

• Geiger Mueller-type sensor phototube detecting UV radiation in the 180 to 260 nm spectral range
• Solar blind design tolerant to black body radiation
• High sensitivity with typical 0.1-second Flame Present Response Time and 0.2-second maximum Flame Loss Response Time
• Two-year shelf life and 10,000-hour MTBF
• Long-distance sensor-to-amplifier signal transmission capability up to 330 m (1000 ft)
• Sealed viewing window rated for pressures up to 428 mbar (6.3 psi)
• Integrated 9 ft (2.7 m) 2-conductor armored cable

Applications

• General Electric (and GE licensee) heavy-duty gas turbines
• Power generation gas turbine flame monitoring
• Industrial compressor gas turbine installations

Technical Specifications

Installation Guidelines

• Amplifier Compatibility: Hardware outputs are designed exclusively for connection to Honeywell EG1033 series amplifier modules (EG1033AA, EG1033AB, EG1033AC).
• Wiring and Distance: Ensure proper routing of the attached 2-conductor armored cable. Sensor-to-amplifier runs can extend up to 330 m (1000 ft).
• Pressure Rating: Verify that process conditions at the viewing interface do not exceed the window rating of 428 mbar (6.3 psi).
• Hazardous Area Mounting: Observe all local codes and area classification constraints when mounting in classified explosive environments.
• Low-NOx Exception Note: Standard LG1093 series detectors may not function as expected on GE/NP DLE (Dry Low NOx) gas turbines; these applications require specialized pre-selected variants.
