  • Patent number: 10996078
    Abstract: Apparatus and associated methods relate to a linear variable differential transformer (LVDT) probe. The LVDT probe includes a plunger rod and a metal sheet formed into a cylinder with a C-shaped cross-section, the metal sheet configured to couple to the plunger rod. In an illustrative example, the coupling may be an interference fit aided by spring retention forces of the metal sheet. The metal sheet may be stamped, formed and applied to the plunger rod without annealing. In another example, the C-shaped metal sheet may be welded to the plunger rod at a distal and/or proximal end. The ratio of relative electromagnetic permeability of the metal sheet to the plunger rod may be greater than 10.

  • Patent number: 10969290
    Abstract: A cold cathode ionization gauge (CCIG) includes an extended anode, a cathode surrounding the anode along a length of the anode, and a feedthrough insulator supporting the anode. The cathode forms a discharge space around the anode to enable formation of a plasma between the anode and the cathode and a resultant ion current flow into the cathode. The CCIG further includes a magnet applying a magnetic field through the discharge space to lengthen free electron paths to sustain the plasma. A shield is electrically isolated from the insulator and shields the insulator from electrons of the plasma. The shield may be mounted to the cathode and surrounds and is spaced from the anode. An electric controller applies voltage between the anode and the cathode to create ionization with plasma discharge between the anode and the cathode, the controller determining pressure based on measured ion current flow to the cathode.
