A Method for Measuring Pressure under Rotating Conditions

Abstract:

A method which can accurately measure surface pressure under rotating conditions is presented. Based on the calibration for strain type pressure sensor, a curve which shows the functional relationship between sensor output signal and actual pressure under different rotational speed is obtained; and the diaphragm deformation caused by centrifugal force can be neglected by the curve. Thus, the actual pressure can be acquired accurately. The factors which may cause errors on the experiment are analyzed. Moreover, the correctional method for the experimental data is attained.
