Abstract
A contaminant detecting system for determining the presence of a miscible or immiscible contaminant in a fluid. The fluid acts as a dielectric between the plates of a capacitive sensing element. The measured capacitance value varies in accordance with the composition of the fluid, to indicate the presence or absence of the contaminant in the fluid.
