Abstract
Miniaturized sensors for fluid viscosity often utilize shear vibrations and thus measure a thin film of fluid. To probe the bulk of a sample, pressure waves can be utilized instead. Then, however, the so-called longitudinal viscosity is determined, which can be equally useful for condition monitoring applications. Moreover, this parameter has not yet been investigated in detail such that material data are scarce. In this paper, we report on a prototype setup utilizing standing acoustic pressure waves in a small sample chamber. The impact of these resonances on the impedance of a PZT transducer is modeled and investigated experimentally. It is demonstrated that with this setup sound velocity and the longitudinal viscosity of liquid samples can be investigated.
