Abstract

A plug gauge includes a housing defining an internal volume and a longitudinal axis AH. The housing includes an opening into the internal volume. The plug gauge also includes a contact element at least partially received in the opening. The plug gauge further includes a plunger at least partially received in the internal volume. The plunger is biased into engagement with the contact element to urge the contact element radially outward from the housing through the opening. The plug gauge additionally includes a sealing member between the contact element and the housing.

Description

technical field [0001] This application relates to bore metrology, and more particularly to sealing plug gauges and related methods for preventing debris from entering the plug gauge. Background technique [0002] Various measuring tools exist for determining the diameter of a cylindrical hole. Measurement tools of this type typically include devices that function by contacting diametrically opposed points within the bore. Examples of this type of measuring tool include plug gauges. A typical plug gauge includes a center housing with a pair of angularly disposed spring-loaded contacts (one on each side of a centerline disposed perpendicular to the longitudinal axis of the housing) and coupled to the contacts and along Longitudinal axis oriented plunger. Movement of the contact along the centerline is translated into movement of the plunger along the longitudinal axis when the housing is inserted into the bore. A measuring tool, such as a dial indicator, is operatively co...
