Analysis of a dynamic pressure measuring system.
Blevins, Roger Allen

A mechanical model of each of the pressure measurement system components enabled adequate definition of the frequency response without having to resort to dynamic calibration. The air column dynamics were described with the second order model transfer function presented by Hougen et al. (9). Recorded values of frequencies of oscillation of air columns compared favorably with those calculated from Equation 3. The calculated amount of damping present in the oscillating air column was small.
