Description
Product Overview
Honeywell LG1093AC01 is a UV Flame Sensor designed for industrial gas turbine flame monitoring applications. It is part of the Honeywell LG1093 series ultraviolet flame detection system and is specifically engineered for use with gas turbines, turbine-driven compressors, and combustion safety systems. The sensor detects ultraviolet radiation generated by hydrocarbon flames and provides a reliable flame-present or flame-loss indication to the associated flame amplifier and turbine control system.
Honeywell LG1093AC01 uses a Geiger-Mueller type ultraviolet phototube sensing element that detects flame radiation within the 180–260 nm ultraviolet spectrum. Due to its solar-blind characteristics, LG1093AC01 is highly resistant to interference from sunlight and black-body radiation sources, making it suitable for outdoor and high-temperature combustion environments. The sensor is commonly integrated with Honeywell EG1033 series flame amplifiers to provide fast and dependable flame detection signals for combustion protection systems.
Honeywell LG1093AC01 has been widely applied in General Electric gas turbine platforms and GE-licensed turbine systems for more than decades due to its proven reliability in combustion monitoring applications. With fast flame response time, long operating life, hazardous-area certification options, and compatibility with turbine safety control architectures, LG1093AC01 provides an effective solution for maintaining safe and stable turbine operation.

LG1093AC01
Main Features and Advantages
Honeywell LG1093AC01 provides a reliable flame monitoring solution for demanding combustion applications where rapid response and high availability are essential. Unlike conventional temperature or visible-light flame monitoring devices, LG1093AC01 uses ultraviolet radiation detection technology, allowing it to identify hydrocarbon flames quickly while minimizing false alarms caused by ambient lighting conditions.
The UV phototube technology used in Honeywell LG1093AC01 provides excellent sensitivity to combustion radiation. The sensor specifically detects ultraviolet emissions produced by hydrocarbon flames, while remaining largely unaffected by visible light and infrared radiation. This solar-blind characteristic makes LG1093AC01 particularly suitable for gas turbine environments where strong external radiation sources may exist.
Fast response performance is one of the major advantages of LG1093AC01. The sensor can typically identify flame presence within approximately 0.1 seconds and detect flame loss within approximately 0.2 seconds when used with the appropriate amplifier system. This rapid detection capability helps turbine protection systems respond quickly to combustion abnormalities and reduce the risk of equipment damage.
Honeywell LG1093AC01 is designed for integration with Honeywell flame amplifier modules such as the EG1033 series. The sensor-amplifier combination provides a complete flame monitoring solution capable of interfacing with turbine control systems, combustion controllers, and safety shutdown logic.
Another important advantage of LG1093AC01 is its suitability for harsh industrial environments. The sensor supports a wide operating temperature range from -40°C to +176°C and is available with hazardous-area approvals for applications requiring explosion protection. This makes it suitable for installation near gas turbines, compressor packages, and combustion equipment.
Honeywell LG1093AC01 also offers long service life and proven field reliability. The LG1093 flame detection technology has been used extensively in turbine applications, including GE and GE-licensed gas turbine systems, where dependable flame monitoring is essential for safe operation.
The compact design, high sensitivity, rapid response, and compatibility with established turbine safety systems make LG1093AC01 a preferred choice for flame supervision applications in power generation and industrial combustion systems.
Applications
Honeywell LG1093AC01 is primarily used in gas turbine combustion monitoring systems where reliable flame detection is required for safe operation. In power generation plants, LG1093AC01 is commonly installed on gas turbines to monitor combustor flame status and provide flame failure protection signals to turbine control systems.
