What are the Linear Pressure Range and Technical Specifications of the ECU Masters Oil Pressure Sensor?

The ECU Masters Oil Pressure Sensor, such as the WHP 7 BAR FUEL OR OIL PRESSURE SENSOR, typically has the following specifications:

  • Pressure Range: The sensor can measure pressures up to 7 bar (approximately 101.5 psi).
  • Accuracy: While the specific accuracy of the ECU Masters sensor is not detailed, similar high-quality sensors often have an accuracy of around +/- 0.5% to 1.5% full scale.
  • Temperature Range: The operating temperature range for such sensors is generally between -40°C to +140°C.

How to Calibrate the ECU Masters Oil Pressure Sensor?

ECU Masters Oil Pressure Sensor

Calibrating an oil pressure sensor like the one from ECU Masters involves ensuring the sensor’s output voltage corresponds accurately to the measured pressure. Here is a general step-by-step process:

  1. Connect the Sensor:

  2. Ensure the sensor is properly connected to the ECU and power supply. Typically, this involves connecting the sensor signal wire, ground, and 5V power supply.

  3. Initial Check:

  4. Verify that the sensor is reading correctly at zero pressure. This is usually around 0.5V to 1V for a 0-5V output sensor.

  5. Measure at Known Pressures:

  6. Use a calibrated pressure source to apply known pressures to the sensor (e.g., 0 psi, 50 psi, 100 psi).

  7. Measure the output voltage at each known pressure using a multimeter.

  8. Create a Calibration Table:

  9. Record the output voltages at each known pressure point.

  10. Create a calibration table or curve that maps the output voltage to the corresponding pressure.

  11. Configure the ECU:

  12. Enter the calibration data into the ECU software. This may involve setting up a lookup table or linear equation that the ECU uses to interpret the sensor’s output voltage.

  13. Test and Validate:

  14. Test the sensor under various operating conditions to ensure it is reading accurately.
  15. Validate the calibration by comparing the ECU’s interpreted pressure readings with actual pressures measured by other means.

What are the Connector Specifications of the ECU Masters Oil Pressure Sensor?

The connector specifications for the ECU Masters Oil Pressure Sensor typically include:

  • Hydraulic Interface: The sensor often uses a 1/8″ NPT (National Pipe Thread) connection for hydraulic interface.
  • Electrical Connector: The electrical connector is usually an integral weatherproof connector, which includes mating connectors, pins, and pin locks.
  • Pin Configuration: The pin configuration typically includes:
    • Ground: One pin for ground connection.
    • 5V Power: One pin for 5V power supply.
    • Signal: One pin for the sensor signal output.
