A resonant sensor based system for measuring viscosity and density is shown and applied to two meas-urement tasks comprising oil characterization in hydraulic systems and measurement of diesel and soot contamination in engine oil. It is demonstrated that from measuring over varying temperature and pres-sure, a variety of additional physical properties can me exploited for online condition monitoring. This encompasses also the heat expansion coefficient and the bulk modulus, which are difficult to measure otherwise.
