Abstract
A plug gauge includes a housing, defining an internal volume, first openings, and second openings. The plug gauge includes first contact elements, each at least partially received in a respective one of the first openings. The plug gauge includes a first plunger in the internal volume and movable relative to the housing. The first plunger is biased to urge the first contact elements radially outward through the first openings. The plug gauge includes a first sensor sensing movement of the first plunger. The plug gauge includes second contact elements, each at least partially received in a respective one of the second openings. The plug gauge includes a second plunger in the internal volume and movable relative to the housing. The second plunger is biased to urge the second contact elements radially outward through the second openings. The plug gauge includes a second sensor sensing movement of the second plunger.
