Abstract: Disclosed herein are measuring assemblies including a measuring assembly for measuring one or more dimensions of a pipe that has an inner surface and an outer surface, which measuring assembly may include: a cylindrical housing; a first probe rotatably coupled to the housing; and a second probe rotatably coupled to the housing and capable of being disposed inside the pipe.

Abstract: A plug gauge including a probe housing defining an internal volume and a longitudinal axis, the probe housing includes a first and second openings, a first contact element having a portion extending through the first opening, a first cam member defining a first axis of rotation, the first cam member being in camming engagement with the first contact element such that movement of the first contact element relative to the probe housing causes corresponding rotation of the first cam member about the first axis of rotation, a second contact element having a portion extending through the second opening, and a second cam member defining a second axis of rotation, the second cam member being in camming engagement with the second contact element such that movement of the second contact element relative to the probe housing causes corresponding rotation of the second cam member about the second axis of rotation.

Abstract: Disclosed herein are measuring assemblies including a measuring assembly for measuring one or more dimensions of a pipe that has an inner surface and an outer surface, which measuring assembly may include: a cylindrical housing capable of being disposed at least in part inside the pipe, the cylindrical housing having an inner housing space and a housing wall with an inner housing surface and an outer housing surface; a bearing disposed in the housing wall; and a probe rotatably coupled to the housing, wherein the probe is capable of providing one or more dimensions of the pipe.
