The goal of the investigations was to evaluate the dynamical properties of air gauges in order to exploit them in such industrial applications as in-process control, form deviation measurement, dynamical measurement. As an important parameter, the time response was analyzed theoretically and experiments were performed in order to verify the proposed calculation model. The analyzed air gauges were applied in the devices for non-contact measurement of roundness and cylindricity, as well as in the contour and waviness measurement device. Because of evident physical conditions of experiments, the input signal should not be treated as an orthogonal step, but as a quasi-trapezoidal step which could be approximated in simulations as a trapezoidal one. The time response indicates that the air gauges with small measuring chambers should be treated as first-order dynamic systems.
