Miniaturized resonating viscometers facilitating measurements at tunable frequencies in the low kHz-range

Abstract

In this contribution two different types of resonating sensors for the viscosity of fluids with adjustable resonance frequencies in the range of 1 kHz to 10 kHz are presented. Analytical models relating measurement data to the viscosity of the examined liquid and measurement results are presented and the benefits of the discussed sensor designs in terms of high tunability and their sensitivity to viscosity are discussed. © 2011 Published by Elsevier Ltd.
