LG1093AC05 | Flame Detector Sensor | Honeywell LG1093

Overview

The Honeywell LG1093AC05 is a gas turbine flame monitoring system designed for detecting UV radiation emitted by hydrocarbon flames. It provides reliable flame detection, ensuring the safety and efficiency of gas turbines used in power generation and compressors. 

Features

Sensor and Detection

• Geiger Mueller-Type Sensor: The phototube detects UV radiation in the 180–260 nm range. It is solar blind and tolerant to black body radiation.
• High Sensitivity: Offers fast flame presence response time of 0.1 seconds and flame loss response time of 0.2 seconds maximum.

Reliability and Performance

• Proven Reliability: Over one billion operating hours and a mean time between failures (MTBF) of 10,000 hours.
• Operating Temperature Range: -40°C to 176°C.
• Operating Distances: Capable of operating up to 330 meters (1000 feet) between the sensor and amplifier.

Amplifier Modules

• EG1033AA: Transistor open collector hardware output.
• EG1033AB and EG1033AC: Relay contacts (SPDT) hardware outputs.
• Voltage Requirements: Supports multiple voltage requirements, including 28 VDC, 20-35 VDC, and 115 VAC.

Certifications and Approvals

• CE Mark: Compliant with European Directive CE mark for EMC 89/336/EEC and LVD 73/23/EEC.
• ATEX Certification: Certified for explosive atmospheres under ATEX Explosive Atmosphere 94/9/EC (EEx d IIA T3 or EEX d IIC T3, Zone 1 and 2).
• Factory Mutual Approval: Approved for use in explosive atmospheres (Class I, Div 1 and 2, Groups B, C, and D).

Application and Compatibility

• General Electric Turbines: Qualified component for GE turbines. Note that it may not work as expected on GE/NP DLE gas turbines (Low-NOx) and requires pre-selected LG1093 units not available via Honeywell.
• Flame Sensor Specifications: Flame sensor has a 1.73" O.D. by 0.14" wide flange and a 2-conductor armoured cable. The viewing window is rated for 428 mbar (6.3 psi).
