30.4.32.11 Fuel Pressure
The following sensors can be configured for the Fuel Pressure input on the GEA 24 or GSU 73:
• Garmin GPT 15G (0-15 PSI, for carbureted engines)
• Kavlico P4055-5020-2 (0-15 PSI, for most carbureted engines)
• Garmin GPT 75G (0-75 PSI, for fuel-injected engines)
• Kavlico P4055-5020-3 (0-75 PSI, for most fuel-injected engines)
• Kavlico P4055-75G (0-75 PSI, for most fuel-injected engines)
• UMA 1EU07D (0-7 PSI differential, for some turbocharged carbureted engines such as the Rotax 914)
• UMA 1EU35G (0-35 PSI, for most carbureted engines)
• UMA 1EU70G (0-70 PSI, for most fuel-injected engines)
• UMA 1EU70D (0-70 PSI differential, for some fuel-injected engines such as the Rotax 912iS/
915iS/916iS)
• UMA 1EM2K (0-2500 PSI, for certain turbine engines)
• Custom sensor
Custom:
This option allows the installer to enter up to 8 points of voltage-to-pressure calibration. See pin
description in Section 23
for allowable input voltage range.
FADEC
: The GEA 24 can be configured to monitor fuel pressure data from the following FADEC
interfaces:
• Rotax FADEC (SCU)
• Lycoming (iE2)
• ULPower
Rotax FADEC engines (912iS/915iS/916iS) that require fuel pressure to be measured relative to manifold
pressure may use a differential pressure sensor such as the UMA 1EU70D. Alternatively, these
installations may use a single-input gauge pressure sensor and change the configuration of the "Pressure
Reference" item to "Manifold Pressure". This does not apply to installations which include the RS Flight
Systems SCU 9iS propeller speed controller and select 'Rotax FADEC (SCU)' for the sensor.
