PressureSensors / OilAndFuel

Oil/Fuel Pressure Sensor

The fuel/oil pressure sensor is a low cost, high performance, media isolated pressure transmitter, designed for the harsh environment of automotive applications. A monolithic silicon element coupled with high level output ASIC circuitry ensures excellent accuracy and long term stability, protected within a rugged, stainless steel housing.

Suitable for the measurement and data logging of fuel, water, air and hydraulic systems. The sensor is supplied as standard with a 0-10 bar gauge pressure range.

With additional EMC protection, low static and thermal errors and high resistance to shock and vibration, the sensor gives trouble free operation at temperatures up to 125oC

Technical Data

Accuracy at 25C < 1% FSD

Stability (1 year) < 0.1%

Overange pressure 2* rated pressure

Burst Pressure 5* rated or 20000psi (whichever is lower)

Pressure cycles > 10 million

Operating temperature -40 to +105 C


There are 3 leads that come from the sensor: the red lead should be attached to the +5v supply from the data logging unit, the black lead should be connected to the ground connection and the white lead should be connected to an analogue input.

Connecting the sensor to a data logger (DL1 or DL2) or DASH2

If the sensor has been supplied by Race Technology with a cable attached then wires from the sensors are:

  • Red - Connect to the +5v reference output from the DL1/DL2/DASH2
  • Black - Connect to ground (0v) on the DL1/DL2/DASH2
  • White - Signal output from the sensor, this can be connected to any of the analogue inputs on the DL1/DL2/DASH2

If the sensor is supplied without cable then please refer to the pin out above.
