Dynamic calibration of air gauges
Original language description
In the paper, the investigations on the dynamic properties of air gauges were presented. The measurement of the amplitudes of back-pressure pk dependent on the input signal circular frequency omega for the group of air gauges with various parameters hasbeen performed. To evaluate the influence of the measuring chamber volume on the dynamical properties, the set of the model chambers have been prepared with different dimensions. The gained results underwent comparative analysis with the results of investigation of the step response revealing the differences between the settings times obtained experimentally from different methods. The examinations of the step response of typical back-pressure air gauge led to the conclusion that its behavior is very close to the first-order dynamical system. The examined air gauges could be successfully exploited in the industrial measurement of values changing in time (dynamical measurement).
