This contribution presents the concept of a resonant sensor for fluid viscosity parameters. A lot of recent work has been focused on resonant sensors for, e.g., shear viscosity and mass density measurements. In this paper the concept of a sensor for the so-called ?longitudinal viscosity? rather than the shear viscosity is introduced. We consider this parameter as equally suited for a lot of condition monitoring applications, in particular for liquids featuring higher viscosities. The associated theory including a simplified 1D model and present measurement results obtained with a first prototype device are outlined.
