Vibrating-wire sensors have been used in a number of instruments built for measurement of the density and viscosity of fluids up to high pressure and in wide temperature ranges. These instruments are based on a rigorous theoretic model describing both the mechanics of oscillation and the hydrodynamic effects arising from the presence of the sample fluid surrounding the vibrating wire. The equivalent circuits proposed in this work are essential in order to interpret the output signals of the sensor in terms of its mechanical parameters. Design choices dictate the type of pertinent electromechanical analogy. The use of equivalent circuits made possible the simultaneous measurement of the density and viscosity of fluids using one single sensor, which is a demonstration of a complete understanding of its behavior.<\/jats:p>","DOI":"10.1063\/1.1148965","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T12:26:29Z","timestamp":1027686389000},"page":"2392-2399","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":47,"title":["Electromechanical model for vibrating-wire instruments"],"prefix":"10.1063","volume":"69","author":[{"given":"A.
