Calibration Pressure
Pressure calibration is the comparison of the output of a device used to measure pressure with that of another pressure measurement device, or pressure measurement standard. This usually involves plumbing the unit under test (UUT) to the standard device and generating a common pressure in the measurement circuit. The outputs of the devices are compared at one or more pressures, typically from the lowest to highest readings of the UUT’s full scale range, or the range for which it is normally used. This comparison process is performed in a chain from the highest level of fundamental pressure realization, down to every day pressure measurement devices, to ensure pressure measurements are accurate and comply with accepted or mandated standards.
