  • Hot-cathode ionization pressure gauge including a sequence of electrodes arranged at a distance from one another in sequence along an axis
    Patent number: 5373240
    Abstract: A hot cathode ionization pressure gauge with the following electrodes, arged at a distance from one another in the specified sequence along an axis:a) a thermionic cathode filament which has a central active part and lateral support parts;b) an essentially flat, diaphragm-like control electrode,c) an essentially flat apertured acceleration electrode andd) an essentially flat ion collector electrode,and with a base plate on which the control electrode, the acceleration electrode and ion collector electrode are mounted, in each case via support means running at right angles to the main part of the relevant electrode and via a support bolt connected to the support means.
