  • Capacitive sensor arrangement for a liquid or gaseous medium, and method of making the same
    Patent number: 6275048
    Abstract: A capacitive sensor for measuring characteristics of liquid or gaseous media has at least two outer carrier boards and a spacer plate that keeps the two outer boards at an exact dimensionally stable spacing from each other. A sensor capacitor is formed by a hollow space in the spacer plate flanked by two metal coatings forming capacitor plates on the inwardly facing surfaces of the outer boards. Two or more capacitors can be formed by stacking the desired number of boards and spacer plates. Ports are provided for the medium to flow into the hollow space or spaces preferably in the spacer plates. Further ports for pressure equalization inside and outside the sensor are formed either laterally in spacer plate margins or directly in the outer boards.
