iMFD Sensor Module SM-Fluid Pressure
*Please read the instructions completely through at least once before proceeding with the
installation to minimize errors.
*DO NOT use this sensor for Fuel Pressure sensing purpose
*Double check polarity of power before powering it on for the first time.
Overview:
(Figure 1) (Figure 2)
1. Connects to 12V-18V power source.
2. Analog outputs (0-5V linear output) *For sensor #1 ONLY
3. Termination jumper. Closed for first SM in iMFD daisy chain.
4. Connects to next SM in iMFD daisy chain or to first DM
5. Connects to previous SM or unconnected if first SM in iMFD daisy chain
6. Connects to PLX Fluid Pressure Sensor. Up to 2 sensors can be connected for 2 channel operation.
7. Fluid Pressure Sensor (150psi). (*Using a sensor not provided by PLX Devices may lead to inaccurate readings due to a
mismatch in calibration)
8. 24k Gold Ring Terminal
9. Molex Connector Terminals
10. Molex 2 Pin Connector
Install the Fluid Pressure Sensor:
1. The PLX Fluid Pressure probe screws into a 1/8 NPT tap.
2. Connect the fluid pressure sensor with the provided 2 pin Molex connector according to the following diagram. It should
connect to the port “G” on the sensor. Connections can be made by crimping the terminals or soldering the terminals
with the provided wire. *Note the orientation of the Molex 2 pin connector. A reverse connection will result in inaccurate
readings and may damage the device.
