23.3.8 TIT (Turbine Inlet Temperature) Sensor
Sensor Description –
Type K grounded thermocouple probe with screw-in type adapter. This type of
sensor is applicable to all turbocharged engines.
General Installation Guidance –
To maintain G3X Engine Indicating System (EIS) measurement
accuracy, thermocouple (TC) wire must be connected directly to the inputs of the GEA 24/GSU 73. If the
supplied sensor wires are not long enough to connect directly to the GEA 24/GSU 73, then Type K TC
extension wire must be used. To minimize risk of breakage, it is recommended that a high-quality stranded
(as opposed to solid) thermocouple wire be used. One such example of appropriate wire is TT-K-22S
Type K thermocouple wire from Omega Engineering.
23.3.9 Bus Voltage Monitor
Bus voltage is normally sensed from an external voltage signal connected to a GEA 24/GSU 73 analog
input (refer to
for interface drawings). Optionally, the GEA 24/GSU 73 can be configured to
measure bus voltage without requiring an external connection, by sensing the voltage of its power supply
inputs. See
for GDU 37X systems and
for GDU 4XX systems (Volts 1 and
Volts 2 Inputs) for configuration guidance.
