UL Power Sensors
The G3X system is capable of monitoring the following engine parameters from the UL Power FADEC
digital interface, when connected to the dedicated FADEC CAN interface on a GEA 24:
•
RPM
•
Manifold pressure
•
Oil pressure
•
Oil temperature
•
Cylinder head temperature
•
Exhaust gas temperature
•
Fuel pressure
•
Fuel flow
•
ECU bus voltage
For UL Power engine installations that do not support a digital interface to the GEA 24, the engine sensors
shown in Table 23-8 may be used.
Table 23-8 UL Power Sensors
Sensor Type
Details/Part Number
RPM
Use ECU tachometer output and select "Electronic Ignition
(2 pulses/revolution)"
Manifold pressure
Use Kavlico P4055-30A-E4A (494-30004-01)
Oil pressure
Use Kavlico P4055-150G-E4A (494-0004-00)
Oil temperature
Use UMA 1B3-2.5R RTD (494-70004-00)
Exhaust gas temperature
Use Type K thermocouples
Cylinder head temperature
Use Type K thermocouples
Fuel pressure
Use Kavlico P4055-50G-E4A (494-30004-02)
Fuel flow
Use ECU fuel consumption pulse output and select "Custom" fuel flow
configuration. UL Power specifies a pulse frequency of 170 Hz at
72 L/hour, which suggests an initial scale factor of 32176.
