1 x INPUT Oil Pressure pick-up (Keller 4-20 mA and VDO resistive 10 bar/150 psi)
Keller 4-20 mA Rotax P/N: 456180
VDO resistive Rotax P/N: 956357 / 956415
Measuring range: 0 to 10 bar / 0 to 150 psi
Application: Oil Pressure (4 Stroke)
1 x RPM pick-up
Measuring range: 0 to 9990 rpm
1 x INPUT Manifold Pressure
Measuring range: 0 to 70 inHg
Note: Sensor probes are not included in the EngiBOX package
Note: Thermocouple sensors must be ungrounded, not be referred to GND or negative external power.

Usage of other instruments in parallel

  • Thermocouple sensors (for EGT and CHT) and Manifold pressure input can be used in parallel with other measurement instruments.
  • To use EngiBOX RPM input in parallel with another RPM instrument depends on capacity of the other instrument. EngiBOX applies a 100 ohm load on RPM. Verify if the other RPM instrument is able to correctly measure RPM with a 100 ohm load applied between RPM input and instrument ground. This is equivalent to EngiBOX RPM usage in parallel with another RPM instrument.
  • Thermoresistance sensors (for OIL T, CHT, CT and Air T) and Oil pressure sensors can not be used in parallel with other measurement instruments.

EngiBOX connections

EngiBOX has several sensor input ports, which can be occupied variably according to the connected engine type.
