What is a Pressure Gauge?
Pressure gauges are the unsung heroes of countless industries, quietly measuring and monitoring the pressure air, gases, or fluids in industrial systems. The dial or digital readout typically displays the pressure level visually. Pressure gauge calibration is essential in many industry to ensure accurate pressure measurement for various applications, from automotive maintenance to industrial manufacturing:
Automotive: Measuring tire pressure, engine oil pressure, and coolant pressure.
Aviation: Measuring fuel and hydraulic system pressures.
Life Sciences: Monitoring blood pressure and other physiological parameters.
Manufacturing: Monitoring and controlling pressure in pipelines, tanks, and equipment.
Pressure gauges play a critical role in ensuring safety, efficiency, and overall system performance but how do you know if your device is giving you accurate readings? The answer lies in calibration.
How to Calibrate a Pressure Gauge:
- To start with, check that the calibrator or standard you’re using has been calibrated in accordance with the manufacturer’s recommendations. If it is already out of calibration, the results of the procedure would be unreliable.
- Connect the pressure gauge that is to be calibrated to the pressure source. Make sure there is a block valve to isolate the pressure source from the rest of the system and a bleeding valve for releasing pressure.
- Set the pointer so that it reads zero on the pressure scale.
- Apply the maximum pressure the gauge can measure and adjust till the gauge being calibrated indicates the right pressure.
- Isolate the pressure source and completely depressurize the system using the bleed valve.
- Verify that the gauge reads zero, or adjust it as needed.
- Repeat steps 4 to 6 till both the readings are accurate.
- If the gauge includes a linearizing adjustment, adjust the pressure source to 50% of the maximum pressure the gauge can measure and check the reading.
- Check if the gauge readings are correct at zero, 50%, and maximum pressure, and adjust it each time until all of them are accurate. This step requires a lot of care and patience.
- After all the readings are correct, write down the gauge’s readings at the applied pressures onto a calibration sheet.
- If you are performing a bench calibration and need to issue a calibration certification, draw a graph plotting the increasing and decreasing applied pressures against the gauge readings.
