This sensor features a Geiger Mueller-type phototube that is tuned to the 180 to 260 nm spectral band, ensuring it remains solar-blind and highly tolerant to black body radiation. Built for heavy-duty power generation and mechanical compressor systems, this unit integrates seamlessly with EG1033 amplifier modules to deliver rapid flame status detection in rugged environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Note that while this sensor is standard on many GE-licensee turbines, it may not function reliably on newer GE\/NP Dry Low NOx (DLE) combustor systems. Low-NOx systems typically require pre-selected, high-sensitivity units that are calibrated specifically for low-emission flame properties.\u003c\/p\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\u003cstrong\u003eApplication Pitfalls \u0026amp; Engineering Notes:\u003c\/strong\u003e Because the sensor relies on detecting UV radiation in the narrow 180 to 260 nm band, any physical obstruction on the viewing window will degrade performance. Hydrocarbon soot, moisture condensation, or oil mist accumulation on the window can block UV light and trigger false flame-out alarms. Routine physical inspection of the window seal and cleaning of the optical path is recommended during planned maintenance outages.\u003c\/p\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\u003cstrong\u003eCommissioning \u0026amp; Wiring Tips:\u003c\/strong\u003e Ensure that the integrated Teflon-shielded cable is routed through dedicated, grounded metal conduit to isolate the weak phototube signal from high-voltage motor starters, ignition transformers, and generator cabling. When terminating the cable at the EG1033 amplifier module, verify that shield continuity is maintained and grounded at one end only to prevent ground loops.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cp style=\"margin: 0; font-weight: bold; color: #9b2c2c;\"\u003eCRITICAL WARNING:\u003c\/p\u003e\n  \u003cp style=\"margin: 0.5rem 0 0 0; color: #9b2c2c; font-size: 0.95rem;\"\u003eEnsure the gas turbine or industrial burner is completely shut down, isolated, and depressurized before attempting installation or replacement of the flame sensor.
