Electrical behavior of a quartz crystal resonator immersed in a pressurized fluid (gas or liquid)

Résumé

A network analyzer connected to a high pressure vessel was used to measure the conductance spectrum in a wide range of frequency (1-250 MHz) of an AT-cut quartz crystal resonator of nominal frequency 3 and 5 MHz totally immersed in a fluid under pressure ranging from atmospheric pressure to 80 MPa. Measurements carried out with several gases (methane, nitrogen, argon, carbon dioxide) and various hydrocarbon liquids (toluene, heptane, nonane, decane, dodecane) show that quartz resonators correctly work when they are fully immersed in pressurized fluids whatever the state gas or liquid and whatever the pressure. At constant pressure, both shifts in frequency and bandwidth follow a regular behavior versus overtone number in a domain limited in the lower range by the influence of the circle edge boundary conditions and by the interference with the anharmonic modes in the upper range. In this working domain, experimental observations were well represented by a model that takes into account the effects of hydrostatic pressure, viscous damping as well as interfacial ones through two parameters.
