ABSTRACT:
A thickness gauge traverse for a gauge such as a nuclear thickness gauge that measures thickness of extruded sheet at numerous locations across the sheet in a system utilizing those measurements to correct thickness of the extrusion. The traverse has a mount supporting the probe of the gauge for movement across the sheet. A motor and motor control electronics rapidly advance the probe from one measurement point to the next, where the mount is stopped permitting the probe to remain for the considerable time necessary to make its measurement without having that time dominate the speed of the gauge's movement from point to point across the sheet.
