  • High vacuum capacitance manometer having Px side open housing
    Patent number: 4587851
    Abstract: A sensor unit for a high vacuum manometer includes a tensioned diaphragm fused on one side to a closed evacuated reference chamber and on the other side to a wall ring of substantially the same diameter as the diaphragm. A removable cap member with a gasket seats against the wall so as to define a pressure receiving chamber bordering the diaphragm. With the cap removed, the surfaces of the diaphragm and ring are all accessible for solvent cleaning and visual inspection, so that the sensor may be repeatedly and reliably decontaminated and the diaphragm restored to its initial characteristics. A method of assembly and cleaning are also shown.
