Concept Studies of Torsional Resonators for Viscosity and Mass Density Sensing Applications
Sprache des Titels:
In this contribution a concept for a torsional oscillators which is electromagnetically driven and read-out is presented. The aim is to experimentally investigate a principle feasibility for a torsional resonator with application for viscosity and mass density sensing. Such a device is particularly interesting as cylindrical torsional resonators for fluid sensing applications are hardly reported but unlike other devices, would yield pure shear wave excitation in the liquid. The design of first conceptual prototypes and measurement results obtained with these devices are presented.
