Abstract
A sensor for capacitively measuring the level of material in a container where the sensor extends through an opening in the container and is connected to measuring circuitry. The sensor includes an electrically conductive, tubular member aligned with the opening. An elongated electrically conductive member is in electrical contact with the circuitry and projects through the container opening and the tubular member such that a space is established between the elongated conductive member and the tubular member so that they are electrically insulated from one another. The space is sealed to prevent entry of moisture therein.
