Product Overview

The Honeywell LG1093AC01 is an LG Flame Detector designed for gas turbine flame monitoring.
It detects UV radiation emitted by hydrocarbon flames and provides a reliable flame/no-flame signal.
This system has proven performance on GE gas turbines and licensee turbines for over 35 years.

Key Features

• Sensor Technology: Geiger Mueller-type phototube.
• Detection Range: UV spectrum 180–260 nm.
• Solar Blind: Immune to sunlight interference.
• Radiation Tolerant: Handles black body radiation effectively.
• High Reliability: 10,000h MTBF; over one billion operating hours in the field.
• Fast Response: Flame detection typically in 0.1 sec, flame loss max 0.2 sec.
• Long Distance Operation: Up to 330 m (1000 ft) from sensor to amplifier.

Applications

• Gas turbines for power generation.
• Industrial compressors requiring reliable flame monitoring.
• Systems using Honeywell EG1033 amplifier modules.
