GONZALEZ BETANCOURT, Mauricio  e  GIRALDO, Juan S. Dynamic characterization of pressure sensors using the principle of mariotte's bottle. Rev.fac.ing.univ. Antioquia [online]. 2014, n.71, pp.202-212. ISSN 0120-6230.

A methodology to evalúate the dynamic characteristics of pressure sensors used in channels or hydraulic models is presented. This is based on the analysis of the ramp and step signals in the time domain for defining the useful range in amplitude and frequency of the sensors. The signals are obtained from the opening and closing of valves present in an aperiodic pressure generator designed with the principle of the Mariotte's bottle.

Palavras-chave : Dynamic metrology; sensor calibration; pressure; channels flow; hydraulic models.
