Aircraft engine temperature sensors are usually one of two types: Thermocouple or Resistive Temperature
Detector (RTD). The GEA 71 is designed to utilize either sensor for EGT and CHT temperature
measurements. Engine Temp Analog inputs are only available with the resistive divider disabled
(1:1 scaling). The maximum differential voltage and the maximum voltage with respect to ground that
can be measured on any Engine Temp Analog Input is 2.5 VDC.
The GEA 71 uses an additional backshell thermocouple to determine the reference junction temperature at
the thermocouple wire-to-copper crimp pin junction.
