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)
Custom: This option allows the installer to enter up to 8 points of voltage-to-pressure calibration. See pin
description in Section 23
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.
Coolant Temperature
The following sensors can be configured to monitor engine coolant temperature on the GEA 24 or GSU 73
MISC TEMP 1 inputs, or the GEA 24 MISC TEMP 2 input:
• UMA 1B10R (or any Pt100-type RTD sensor)
• Rotax 965531 (or any similar VDO 50-150°C thermistor sensor)
• Rotax 966385
Rotax 912iS: For the GEA 24, select "Rotax Coolant Temp (FADEC)" for the MISC TEMP 1 input to use
coolant temperature data from the Rotax 912iS FADEC interface.
Custom Temp: This option can be used to monitor most temperature values, and allows the installer to
customize the name of the gauge. Provided selections are an RTD, thermistor, or Type J or K
thermocouple are provided.
Miscellaneous Temperature
The following sensors can be configured to monitor a single miscellaneous (AUX) temperature using the
GEA 24 or GSU 73 MISC TEMP 1 inputs, or the GEA 24 MISC TEMP 2 input:
• Thermistor (any 50-150°C thermistor such as the Rotax 965531, 966385, or the VDO 320-XXX
series)
• UMA 1B10R, UMA 1BXR-C (or any Pt100-type RTD sensor)
• Type J or Type K thermocouple
