Pressure calibration is vital for industries like oil and gas, automotive, and aerospace. However, common issues can affect accuracy:

1. Zero Drift: Caused by mechanical wear or temperature changes. Solution: Regular maintenance and recalibration.

2. Hysteresis: Occurs when the output differs during increasing and decreasing pressure. Solution: Use high-quality sensors with minimal hysteresis.

3. Contamination: Dirt or moisture can affect readings. Solution: Clean and inspect equipment regularly.

By addressing these issues, you can ensure reliable pressure measurements and avoid costly downtime.

Key takeaways:

• Zero drift, hysteresis, and contamination are common issues.

• Regular maintenance and high-quality equipment are key to solving them.
