SPECTRA GT30 Gas Turbine Flame Sensor

Spectra GT30


The SpectraTM GT30 is easily mounted directly to the turbine case or on a short standoff pipe via a 3/4 inch NPT internal thread. The two-wire, 24 VDC loop-powered solid-state sensor is fully self-contained, therefore it does not require a separate amplifier. AMETEK offers various cabling options depending on the application.


For turbine retrofits and upgrades, the sensor can be connected directly to a control system, through a relay module or with a frequency converter to mimic the older technology pulse output style.
