ABSTRACT:
A temperature insensitive gauge is disclosed. The temperature insensitive gauge includes a frame having a first and second caliper assembly movably mounted on the frame. The first and second caliper assemblies engage a workpiece. A mechanism for measuring the relative movement between the caliper assemblies is associated with the assemblies. The measuring mechanism provides measurement information on the size of the workpiece. A compensating mechanism is associated with the caliper assemblies for reducing thermally induced dimensional changes in the gauge.
