Pressure calibration involves verifying the accuracy of pressure sensors, gauges, and transmitters. Here’s a step-by-step guide:

1. Select a Calibrator: Choose a device with a wider range and higher accuracy than the unit under test.

2. Connect the Equipment: Attach the pressure source and sensor to the calibrator.

3. Apply Pressure: Gradually increase and decrease pressure while recording readings.

4. Compare Results: Check for deviations between the sensor and calibrator.

5. Adjust if Necessary: Fine-tune the sensor to match the calibrator’s readings.

Key takeaways:

• Pressure calibration ensures accurate pressure measurements.

• Follow a systematic process for reliable results.
