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/915iS
: For the GEA 24, select "Rotax FADEC" to use oil pressure data from the Rotax 912iS/
915iS FADEC interface.
The Rotax 456180 and 956413 oil pressure sensors require an external resistor for proper
functioning (see Figure 31.2
for GEA 24 and Figure 31.3 for GSU 73).
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/915iS:
For the GEA 24, select "Rotax FADEC" to use oil temperature data from the Rotax
912iS/915iS FADEC interface.
Fuel Pressure
The following sensors can be configured for the Fuel Pressure input on the GEA 24 or GSU 73:
• Kavlico P4055-15G (0-15 PSI, for most carbureted engines)
• Kavlico P4055-50G (0-50 PSI, for most fuel-injected engines)
• UMA NAEU07D (0-7 PSI differential, for some turbocharged carbureted engines such as the
Rotax 914)
• UMA N1EU35G (0-35 PSI, for most carbureted engines)
• UMA N1EU70G (0-70 PSI, for most fuel-injected engines)
• UMA N1EU70D (0-70 PSI differential)
Carburetor Temperature
The following sensors can be configured to monitor carburetor temperature on the GEA 24 or GSU 73
MISC TEMP 1 inputs, or the GEA 24 MISC TEMP 2 input:
• UMA 1B10R
• Rotax 965531
• Rotax 966385
Coolant Pressure
The Kavlico P4055-50G sensor can be configured to monitor engine coolant pressure on the GEA 24 or
GSU 73 MISC PRESS input.
