Honeywell LG1093AA24 / 261A1812P012 UV Flame Sensor

Product Brief Description

The Honeywell LG1093AA24 with part suffix 261A1812P012 is a heavy-duty ultraviolet flame sensor equipped with factory integrated shielded cable, designed to pair with Honeywell EG1033 flame amplifier units. It detects ultraviolet radiation emitted by gas and light oil combustion flames. Built with stainless steel housing, wide operating temperature range and IP65 protection, this UV probe delivers stable flame signal transmission under high vibration and thermal radiation conditions, commonly used for gas turbine, boiler and industrial burner management safety systems.

Product Functions

• Capture ultraviolet radiation within 250~350nm spectrum generated by natural gas and light oil flames
• Convert UV flame radiation into analog electrical signal and transmit to matched EG1033 flame amplifier via pre-wired shielded cable
• Built-in current-limiting resistor protects the sensing tube against electrical surge and transient voltage damage
• 3/4" NPT mounting thread for direct installation on burner sight ports of gas turbines and industrial boilers
• High vibration and thermal resistance design for continuous long-term operation inside turbine enclosures and furnace areas
• Work together with flame amplifier to judge flame presence or loss and trigger safety fuel shutoff interlock protection

Application Scenarios

• GE heavy-duty gas turbine combustion flame safety monitoring systems
• Power plant gas-fired boilers, waste heat boilers and industrial furnace burner management
• Oil & gas refinery process heaters and thermal oxidizer flame safeguard control
• Onshore and offshore gas turbine generator combustion supervision
• Spare replacement and retrofit projects for Honeywell LG1093 series UV flame sensors
