DIELECTRIC CONSTANT DETECTOR

摘要

DIELECTRIC CONSTANT DETECTOR A dielectric constant detector, having a sample cell and a reference cell, is provided which is useful to provide an electrical signal that is proportional to the concentration of a component being passed through the dielectric constant detector. The fluid to be analyzed together with a reference fluid is provided to the sample cell while only the reference fluid is provided to the reference cell. The difference in the capacitances of the two cells is utilized to determine the concentration of a component passing through the sample cell. The sample and reference cells are adjusted in such a manner that the capacitance of each cell is substantially equal when the same fluid is in both cells so as to substantially reduce the signal-to-noise ratios for the dielectric constant detector.
