Honeywell LG1093AA44 UV Flame Sensor with 4.9m Integrated Cable

Product Brief Description

The Honeywell LG1093AA44 is an ultraviolet flame sensing probe equipped with a factory pre-assembled 4.9-meter (16ft) cable, designed to pair with Honeywell EG1033 flame amplifier units. This UV sensor detects ultraviolet radiation emitted by hydrocarbon flames on gas and oil burners. It adopts a rugged metal housing and built-in current-limiting resistor, delivering reliable flame presence signal transmission for GE frame gas turbines and industrial burner management systems. The integrated cable eliminates field wiring splicing and maintains stable UV signal transmission under high vibration and high-temperature turbine environments.

Product Functions

• Capture ultraviolet radiation (1850~2650 angstrom spectrum) from gas and light oil combustion flames
• Convert flame UV signal into measurable electrical signal and transmit to EG1033 flame amplifier via 4.9m integrated cable
• Internal 511Ω current-limiting resistor protects the sensor against electrical surge damage
• 3/4" NPT mounting thread for direct installation on burner sight ports of gas turbines and boilers
• Resist high vibration and thermal radiation in turbine enclosures, suitable for continuous long-term operation
• Work with flame amplifier to realize flame on / off judgment and safety interlock for burner trip protection

Application Scenarios

• GE Frame 5, Frame 6, Frame7, Frame9 heavy-duty gas turbine combustion flame monitoring
• Power plant gas-fired boiler, waste heat boiler and industrial furnace burner safety systems
• Oil & gas refinery process heaters and thermal oxidizer flame safeguard control
• Onshore and offshore gas turbine generator unit combustion supervision
• Retrofit replacement projects for Honeywell LG1093 series UV flame sensors
