Honeywell LG1093AC01 | LG1093 Flame Detector

Manufacturer Information

• Manufacturer: Honeywell
• Product Number: LG1093AC01
• Product Type: LG Flame Detector

Honeywell Gas Turbine Flame Monitoring System

The Honeywell LG/EG flame monitoring system detects UV radiation emitted by a hydrocarbon flame and provides an output signal to indicate a flame or no-flame condition. This system has delivered proven performance on General Electric (GE) gas turbines and those of GE licensees for over 35 years.

Sensor Technology

• Type: Geiger Mueller-type sensor phototube
• Detection Range: UV radiation in the 180–260nm spectrum
• Key Features:
  • Solar blind (immune to sunlight interference)
  • Tolerant to black body radiation
  • Long service life: 10,000h MTBF (Mean Time Between Failures)
  • Over one billion (10⁹) operating hours in the field

Applications

• Gas turbines for power generation and compressors

Technical Specifications

• Temperature Range: -40°C to +176°C
• Hardware Outputs:
  • Compatible with EG1033 amplifier modules only
  • EG1033AA: Transistor open collector
  • EG1033AB / EG1033AC: Relay contacts (SPDT)

Performance Features

• High sensitivity with fast flame detection response time (0.1 sec typical)
• Flame loss response time: Maximum 0.2 sec
• Amplifier Compatibility: Supports multiple voltage requirements:
  • 28 VDC
  • 20-35 VDC
  • 115 VAC
• Operating Distance: Up to 330m (1000ft) from sensor to amplifier
• Qualified component for General Electric turbines

Compliance & Certifications

• European Directives:
  • CE Mark for EMC 89/336/EEC, LVD 73/23/EEC
  • ATEX Explosive Atmosphere 94/9/EC (EEx d IIA T3 or EEx d IIC T3, Zone 1 & 2)
• Factory Mutual Approval:
  • Explosive atmospheres (Class I, Div 1 and 2, Groups B, C, and D)

Important Notes

• Honeywell LG1093 series may not work as expected on GE/NP DLE gas turbines (Low-NOx). These applications require pre-selected LG1093 units, which are not available via Honeywell.
