8.2.5.1 Fuel Pressure Sensor
Kavlico P4055-15G-E4A - 0 – 15 psiG pressure transducer for all carbureted engines.
Kavlico P4055-50G-E4A - 0 – 50 psiG pressure transducer for all fuel injected engines.
UMA N1EU35G-CS - 0 – 35 psiG pressure transducer for carbureted engines.
UMA N1EU70G-CS - 0 – 70 psiG pressure transducer for fuel injected engines.
Lycoming fuel injected series engines have a maximum fuel pressure of 35 psi at the inlet
to the fuel pump and 45 psi at the inlet to the fuel injector. Lycoming EIS display ranges
are typically set to correspond with the pressure at the inlet to the fuel injector.
Continental EIS display ranges are typically set to correspond to unmetered fuel pressure
values.
8.2.5.2 Manifold Pressure Sensor
Kavlico P4055-30A-E4A - 0 – 30 psiA pressure transducer. This pressure sensor is applicable to
Continental, Jabiru, Lycoming and Rotax, engines.
UMA N1EU70A-CS - 0 – 70 psiA pressure transducer. This pressure sensor is applicable to Continental,
Jabiru, Lycoming and Rotax, engines.
8.2.5.3 Oil Pressure Sensor
Kavlico P4055-150G-E4A - 0 – 150 psiG pressure transducer. This pressure sensor is applicable to
Lycoming and Continental engines.
Rotax P/N 956413 or 956415 pressure transducer - These pressure sensors are applicable to Rotax
engines.
Jabiru Oil Temperature Sensor - See Jabiru guidance for sensor installation.
UMA N1EU150G-CS - 0 – 150 psiG pressure transducer. This pressure sensor is applicable to
Continental, Jabiru, Lycoming and Rotax, engines.
8.2.5.4 Coolant Pressure Sensor
Kavlico P4055-50GE4A - 0 – 50 psiA pressure transducer. This type of sensor is applicable to all liquid-
cooled engines.
8.2.6 RPM (Revolutions Per Minute)
UMA 1A3C-2 - Standard mechanical tach drive sensor (0 – 5 volt square wave, 2 pulses per crankshaft
rev)
UMA N/T1A9-X - Magnetic pickup tach sensor (installed on mag bleed port)
Electronic Ignition - Tach signal output at 2 pulses/rev (4 cylinder engines) or 3 pulses/rev (6 cylinder
engines)
Jabiru Alternator - Direct connection to alternator output
Rotax Trigger Coil RPM Sensor - This pressure sensor is applicable to Rotax engines. Refer to Rotax
