Product Brief Description

The Honeywell LG1093AA26, also marked as GE part number 261A1812P013, is an ultraviolet UV flame detector sensor designed for gas turbine and boiler combustion safety monitoring. It features 61ft integrated shielded cable, adopting UV spectrum detection technology to identify flame presence reliably and distinguish real flame signals from hot background radiation. Built for high-temperature combustion chambers, this flame sensor sends flame status signals to turbine control systems for ignition confirmation and flame loss protection, widely used as critical spare parts for power generation combustion safety systems.

Product Features & Functions

• UV spectrum flame detection, insensitive to hot furnace background infrared radiation
• 61 feet (18.6m) integrated teflon shielded cable, 350VDC rated
• Wide operating temperature range from -40°C up to +177°C for furnace mounting
• 3/4 inch NPT internal thread for simple mechanical installation on burner housings
• High noise immunity, minimizes false flame alarms in harsh combustion environments
• Continuous flame monitoring, outputs flame present / flame loss signal to control logic
• Pressure rated window, suitable for gas turbine and industrial boiler combustion chambers

Application Scenarios

• Industrial gas turbine combustion chamber flame safety monitoring
• Coal / gas fired boiler burner flame detection and flame trip protection
• Power plant combined cycle unit combustion safety interlock systems
• Oil & gas industrial furnace, thermal process burner monitoring
• Turbine control system maintenance, retrofit and spare sensor replacement
