£105.00 £87.50 TAX FREE

GENERAL FEATURES

  • Rated at 150 psi
  • Rated for oil and fuel use
  • 5V DC operation
  • Output is 0.5V – 4.5V

Description

    • 150 psi Oil / Fuel Pressure Sensor

      Output voltage is 0-5 – 4.5V, where 0.5V = 0 psi gauge and 4.5V = 150 psi gauge.

      The transfer function for use with Race Technology, in psi, is y = -18.75 + 37.5 * x.

      The analogue calibration, if connecting to the external input on a Select ECU is as follows:

      The sensors are provided with a pinout diagram:

      Instructions

      Here is the test that you can do with a multimeter to see if the sensor is wired up and working correctly:

      • Unplug the connector from the sensor.
      • Switch the multimeter to the 20V range.
      • Turn on the ignition.
      • Measure the voltage between pins 1 and 2 on the connector, remembering that they will be reversed when looking into the plug, rather than the sensor. With the negative probe (black) on pin 2, and the positive probe (red) on pin 1, you should measure 5V±0.2V. If it doesn’t, then check the wiring back to the ECU or datalogger / dash to find out if the 5V or the 0V is disconnected, and divide the problem as any other electrical problem.
      • Measure the voltage on pin 3 with respect to ground, with the sensor unplugged. It should be about 0V. If not, check to see if it’s shorted to the 5V supply somewhere.
      • Connect the sensor. Backprobe to measure the voltage between pins 1 and 2. It should still be 5V.
      • Backprobe to measure the voltage on pin 3 with respect to pin 2. With no pressure, it should be 0.5V.
      • With pressure applied, it should read in the range specified above (eg 37.5 psi would read 1.5V).
      • If this reads correctly, check the voltage back at the ECU or datalogger / dash input to check the wiring.
