    Abstract: The apparatus described includes a fixed plate and a movable plate mounted to vibrate relative to the fixed plate in a plane parallel to the plane of the fixed plate. The plates are spaced apart so that fluid can be placed therebetween. A drive system maintains the movable plate vibrating at its resonant frequency. The drive system uses a sinusoidal drive with a linear transducer to facilitate determination of viscosity simply by measuring the peak driving force.
