TIT (Turbine Inlet Temperature) Sensor
Sensor Description:
Type K grounded thermocouple probe with screw-in type adapter.
General Installation Guidance:
To maintain G900X/G950 Engine Indicating System (EIS) measurement accuracy, thermocouple (TC)
wire must be connected directly to the inputs on the GEA. If the supplied sensor wires are not long
enough to connect directly to the GEA, 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 would be TT-K-22S Type K thermocouple wire from
Omega Engineering.
5.6.2.4
Carb Temp (Carburetor Temperature) Sensor
Sensor Description:
Threaded ¼-28 Platinum Resistance Temperature Detector (RTD) probe
General Installation Guidance:
1.
Locate and remove the threaded ¼-28 brass plug (Figure 5-7 and Figure 5-8) on the side of the
carburetor as shown in Figure 5-7 If a threaded plug is not present, as is the case with many very
old carburetors, consult the engine and/or carburetor manufacturer for instructions on how to drill
and tap the lead plug adjacent to the butterfly valve.
2.
Install a very small amount of thread lubricant on the probe threads and insert into the carburetor
(Figure 5-9).
3.
Connect the supplied connector to the appropriate inputs on the GEA as referenced in the
G900X/G950 interconnects in Appendix F-J. Secure the connector and wire assembly to an
appropriate location in the engine compartment to provide strain relief.
