Note générale : Dynamic systems Langues : Anglais (eng) Mots-clés : Dynamic  response  Piezoresistive  devices  Pressure  gauges  Pressure  transducers  Step  response Index. décimale : 553 Géologie économique. Minérographie. Minéraux. Formation et gisements de minerais Résumé : In the paper, the investigations on the dynamic properties of air gauges are presented. As an important parameter, the time response underwent the analysis. 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 has been performed, too. The obtained results underwent comparative analysis with the results of investigation of the step response. The examinations of the step response of typical back-pressure air gage with small measuring chamber and with a piezoresistive pressure transducer 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).
