Manifold Pressure
The following sensors can be configured for the Manifold Pressure input on the GEA 24 or GSU 73:
• Kavlico P4055-30A
• Kavlico P500-30A
• UMA N1EU70A
Rotax 912iS: For the GEA 24, select "Rotax FADEC" for the manifold pressure configuration to use
manifold pressure data from the Rotax 912iS FADEC interface.
Engine Torque: This input provides for display of torque for turbine engine applications using common
torque pressure sensors. This input asl allows the use of a Kavlico oil pressure sensor, or if "Engine
Torque (Custom)" is selected the installer can enter up to 8 points of voltage-to-torque calibration.
Custom: This option allows the installer to enter up to 8 points of voltage-to-pressure calibration. See pin
description in Section 23
Oil Pressure
The following sensors can be configured for the Oil Pressure input on the GEA 24 or GSU 73:
• Kavlico P4055-150G
• UMA N1EU150G
Rotax/Jabiru oil pressure sensors: Rotax oil pressure sensor part numbers 456180, 956413, and 956415,
and Jabiru / VDO oil pressure sensor part number 360-003 (or similar VDO 0-5 Bar pressure sensor) are
supported. For the GEA 24, these sensors connect to the Oil Pressure Input and are configured using the
same page. For the GSU 73, these sensors connect to a general purpose (GP) input.
Rotax 912iS: For the GEA 24, select "Rotax FADEC" to use oil pressure data from the Rotax 912iS
FADEC interface.
NOTE
The Rotax 456180 and 956413 oil pressure sensors require an external resistor for proper
functioning (see
Custom: This option allows the installer to enter up to 8 points of voltage-to-pressure calibration. See pin
description in Section 23
Oil Temperature
The following sensors can be configured for the Oil Temperature input on the GEA 24 or GSU 73:
• UMA 1B3-2.5R
• Rotax 965531
• Rotax 966385
• Jabiru / VDO 320-021 (or similar VDO 50-150°C thermistor sensor)
Rotax 912iS: For the GEA 24, select "Rotax FADEC" to use oil temperature data from the Rotax 912iS
FADEC interface.
