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.
