Spectra GT30 Gas Turbine Flame Sensor
Eliminate false
turbine trips and performance uncertainty with AMETEK’s new SpectraTM GT30
Flame Sensor. The GT30 is an extremely robust, compact optical flame
sensor that receives UV energy from the combustion process and
transmits a 4-20 mA analog signal proportional to flame intensity. The
GT30 operates continuously at 257OF (125OC)
without cooling or at mounting temperatures up to 700OF (371OC)
and an operating temperature of 400OF (204OC)
with the use of an optional cooling coil. The GT30 can
withstand combustion pressures up to 30 Bar (435 psi) so that no
intermediate windows or pressure barriers are required.
INSTALLATION
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.
RETROFITS AND
UPGRADES
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.
