Honeywell LG1093AC01 Flame Detector

Overview

The Honeywell LG1093AC01 flame detector is a highly efficient and reliable solution for monitoring gas turbine flames, particularly suited for power generation and compressor applications. Utilizing advanced UV radiation detection technology, it ensures precise flame detection.The Honeywell LG1093AC01 flame monitoring system detects UV radiation emitted by hydrocarbon flames, providing a clear output signal that indicates the presence or absence of flame. With over 35 years of proven performance, this system is well-regarded for use on General Electric (and GE licensee) gas turbines.

Key Features

• Proven Performance: Trusted for over 35 years on General Electric gas turbines.
• High Sensitivity: Utilizes a Geiger Mueller-type sensor phototube to detect UV radiation in the 180-260 nm range.
• Durability: Offers a two-year shelf life and a Mean Time Between Failures (MTBF) of 10,000 hours.
• Wide Temperature Range: Operates effectively in temperatures ranging from -40°C to 176°C.
• Hardware Outputs: Compatible with EG1033 amplifier modules:
  • EG1033AA: Transistor open collector
  • EG1033AB and EG1033AC: Relay contacts (SPDT)
• Fast Response Times:
  • Flame Present: 0.1 seconds (typical)
  • Flame Loss: 0.2 seconds (maximum)
• Versatile Voltage Support: Compatible with 28 Vdc, 20-35 Vdc, and 115 Vac power supplies.
• Long Distance Operation: Capable of operating at distances up to 330 meters (1000 feet) from the amplifier.
• Compliance: Meets CE mark for EMC 89/336/EEC, LVD 73/23/EEC, and ATEX Explosive Atmosphere 94/9/EC standards. Also approved by Factory Mutual for explosive atmospheres.

Applications

• Gas Turbines: Ideal for power generation and compressor applications.
• Safety: Qualified for use in explosive atmospheres with CE and ATEX certifications.
