A6.2 - Density-Viscosity Measurement Cell for Electrodynamic-Acoustic Resonators

F. Lucklum & B. Jakoby
Miniaturized physical sensors for precise density and viscosity analysis are required as supplement and replacement for complex and expensive laboratory instruments. Utilizing miniature mechanical resonators as transducers, one can greatly reduce the necessary liquid volume, measurement time, and complexity of the experimental setup. Electromagnetic-acoustic transduction in mechanical resonators has been established as a low cost alternative to the ubiquitous piezoelectric or capacitive methods with unique advantages in terms of suitable materials, vibration mode flexibility, and...
