Abstract

A sensor probe for analysis of a fluid includes a base, and a pair of electrodes and a pair of shield members protruding from the base for insertion into the fluid. The electrodes have electrical oscillations generated therein for measurement of electromagnetic properties of the fluid, such as permittivity. The shield members are disposed outside the electrodes and have a dual purpose of electromagnetically shielding the electrodes and having vibrations generated therein for measurement of physical parameters of the fluid, such as density or viscosity. Thus, the single sensor probe can provide measurements of both electromagnetic properties and physical properties of the fluid.
