Development of a Nonpenetrating Inductance Probe for Measuring Lubricating Film Thickness in a Dynamic Seal.

摘要

A report is made on the development of a nonpenetrating inductance type proximity probe. The probe was designed to measure the film thickness between the faces of a dynamic seal. The inductance probe design equations, along with computer programs to solve them, are presented. The inductance probe was designed to measure the distance between the faces of a dynamic seal without penetrating the face of the seal. The programs that are presented may be modified slightly and applied to many different situations.
