About Pressure Calibration

Pressure calibration compares the pressure measurement value of a device under test, such as a pressure gauge with a known calibrated pressure measurement standard such as a deadweight tester or high accuracy reference pressure sensor. 

This is typically performed by plumbing both the device under test and pressure measurement standard to a common stable pressure source.  The variable output of the pressure source such as a pneumatic or hydraulic pump can steadily adjust the source pressure for comparison measurements throughout the range of the device under test.  Recording the deviation between the device under test and the calibrated reference standard will allow you to calculate the error and uncertainty ratio required to determine if the device under test is within tolerance and report the results on the calibration certificate or test report
