ABSTRACT:
An elongated conductive casing is filled with a dielectric material and has an opening at one end. The dielectric material forms a surface across the opening, and a plate member is disposed on the surface to form the sensitive arm of the capacitive probe. Formed within the casing are four capacitors, including the sensitive arm, which form a capacitive probe.
