  • Digital fluid analyzer using capacitive sensing
    Patent number: 4675596
    Abstract: Apparatus for determining the dielectric constant of a fluid as a measure of possible contaminants therein. A reference fluid sample having a known dielectric constant is first placed in a capacitive dielectric sensor and then the fluid to be analyzed is placed in the sensor. By comparing the measured values, an indication is provided of the degree of contamination of the analyzed fluid.
