METHOD OF ADJUSTING CAPACITIVE PRESSURE GAUGE Russian patent published in 2004 - IPC

Abstract RU 2239806 C2

FIELD: measuring engineering.

SUBSTANCE: method includes pressurizing the receiving chamber up to the pressure corresponding to the initial regime of calibration, setting the capacities corresponding to the frequency values of autogenerators, setting pressure in the receiving chamber different from the atmospheric pressure, comparing the frequency difference of the autogenerators with the value of pressure corresponding to the calibration characteristic, and correcting the characteristic when the values are different.

EFFECT: enhanced accuracy of measurements.
