Honeywell LG1093AA04 LG1093 UV Flame Sensor

Description

The Honeywell LG1093AA04 is a ultraviolet (UV) flame sensor designed for flameout protection in industrial gas turbine applications. As part of the LG1093 sensor family, the LG1093AA04 utilizes a Geiger Mueller-type sensor phototube to detect ultraviolet radiation emitted by hydrocarbon flames in the 1800 to 2600 angstrom spectrum. The sensor is engineered to be solar blind and tolerant to black body radiation, producing a precise output signal to indicate flame presence or absence to the monitoring system. This unit features a 3/4 inch internal NPT mounting interface and comes equipped with a 16-foot (4.9 m) Teflon shielded cable with a 1-inch external conduit thread for integration with flame monitoring control panels.

Features

• Geiger Mueller-type sensor phototube detecting ultraviolet radiation at 1800 to 2600 angstroms
• Solar blind operation with tolerance to black body radiation
• Fast response time (0.1 sec typical response when paired with EG1033 amplifier)
• Long operational life with 10,000 hours MTBF and 2-year shelf life
• 3/4 inch internal NPT mounting interface
• Integrated 16-foot (4.9 m) Teflon shielded cable with 1 inch external conduit thread
• Operating capability up to 1000 feet distance from sensor to amplifier

Applications

• Industrial power generation gas turbines
• Gas turbine pumping stations
• Ship-board power generation systems
• Hydrocarbon flame monitoring in industrial power plants

Technical Specifications

Installation Guidelines

• Secure the sensor onto the turbine housing via the 3/4 inch internal NPT mounting interface.
• Ensure the optical window and mounting location maintain clean sight lines to the hydrocarbon flame zone.
• Route the integrated 16-foot Teflon shielded cable through protective 1-inch external conduit threading to the control panel.
• Maintain maximum wiring distance within 1000 feet between the sensor unit and the associated EG1033 amplifier.
• Ensure proper conduit sealing when installing in hazardous or explosive atmospheres.
