How to Calibrate Pressure Gauges - 20 Things You Should Consider


How to Calibrate Pressure Gauges

Pressure gauges are very common instruments in the process industry. As with any instruments, pressure gauges need to be calibrated at regular intervals to ensure they are accurate.

Read this white paper and learn how to calibrate pressure gauges and 20 things you should consider: 

1. Accuracy classes
2. Pressure media
3. Contamination
4. Height difference
5. Leak test of piping
6. Adiabatic effect
7. Torque
8. Calibration/mounting position
9. Generating pressure
10. Pressurizing/exercising the gauge
11. Reading the pressure value (resolution)
12. Number of calibration points
13. Hysteresis (direction of calibration points)
14. “Tapping” the gauge
15. Number of calibration cycles (repeatability)
16. Adjustment/correction
17. Documentation – calibration certificate
18. Environmental conditions
19. Metrological traceability
20. Uncertainty of calibration (TUR/TAR)
