EGT Measurement
Mounting Location
Individual Cylinder EGT 1-2 inches from exhaust port
Turbine Inlet Temperature 2-3 inches from turbine inlet
Cylinder Bank EGT Header collector
When using both thermocouples for comparison (bank 1 EGT and bank 2 EGT for
example), make sure to mount both thermocouples in a similar fashion (distance from
port, tip depth, tube diameter, etc) so the readings are not influenced by installation
differences.
Connecting the Thermocouple
Slide the supplied heat shrink onto the sensor cable. Connect the RED wire from the
thermocouple to the RED wire on the harness and the YELLOW wire from the
thermocouple to the YELLOW wire on the harness using the supplied 4-40 screws and
hex nuts. Make sure the connections are not touching. Center the heat shrink over the
connections and apply mild heat to the heat shrink until it shrinks over the connections.
See Figure 7.
