DUAL TONE MEASUREMENT OF CONDUCTIVITY AND DIELECTRIC PROPERTIES

摘要

The invention relates to a method of simultaneously determining both the conductivity and dielectric properties of a sample such as lubricating oil or a fuel. First and second signals are applied to a test cell through a combiner. Output of the cell is measured by a pair of frequency selective AC voltage measuring devices through a load on the output of the test cell. Through simultaneous readings, conductivity and dielectric properties are accurately calculated rather than estimated.
