A2.4 - A Suspended Plate In-Plane Resonator for Rheological Measurements at Tunable Frequencisies

M. Heinisch, E. K. Reichel & B. Jakoby
In this contribution a rheometric sensor based on a suspended in-plane vibrating plate with tunable resonance frequencies is presented. A sample liquid is subjected to time harmonic shear stress induced by a vibrating plate. By measuring the resonant behavior of this fluid-structure interaction, the liquid’s rheological properties such as viscosity and mass density can be deduced. The sensor consists of a non-conductive platelet and two conductive tungsten wires placed in a constant magnetic field. The...
