What Is Pressure Instrument Calibration?
Pressure instrument calibration is a controlled process of comparing the indication or output of a pressure measuring instrument with an appropriate reference standard under defined conditions.
The purpose is to determine the relationship between the instrument indication and the reference pressure and to document the resulting measurement information.
Depending on the instrument and application, pressure calibration may involve hydraulic pressure, pneumatic pressure, vacuum or other applicable pressure ranges.
Calibration is different from repair or adjustment. Calibration determines measurement performance, while adjustment or repair changes the instrument’s performance where technically possible and appropriate.
