Abstract
The parts of a measuring sensor include an electrode mounted on a conductive body and insulated therefrom. Part of the electrical capacitance between the electrode and the body is determined by the dielectric constant and conductivity of the material in which the electrode and body are immersed. A screening band is provided along part of the length of the electrode so as to shield the electrode from the electrical effects of the material so that only selected levels of material will affect the capacitance. The sensor is ideal for use in enamelled steel vessels.
