30.4.32.17 Engine Torque
For turbine engines, the GEA 24 Manifold Pressure input can be used to measure engine torque. Typically
this takes the form of a pressure measurement that is converted to a torque display using installer-provided
calibration.
The following standard pressure sensors can be configured for measuring turbine engine torque on the
GEA 24 Manifold Pressure input:
• Garmin GPT 150G
• Kavlico P4055-150G (0-150 PSI)
• Custom sensor
If a standard pressure sensor is configured, the installer can to enter up to 8 points of pressure-to-torque
calibration. For other sensor types, select “Engine Torque (Custom)” and enter up to 8 points of voltage-to-
torque calibration. Refer to pin description in Section 25
for allowable input voltage range.
The following two screenshots are an example of an installer-defined torque gauge. In this example, a
Pavlico P4055-150G pressure sensor is used. The gauge spans from 0 to 108 psi with green, yellow, red ,
and a red + alert range.
