Abstract
A scanner for moving sheet materials such as a paper making machine provides the gauging heads which measure parameters such as basis weight and moisture entirely inside an enclosed tubular beam. Each gauging head is driven in a cross direction perpendicular to the moving sheet direction and includes a seal belt for dust and dirt protection by covering a slot in the beam, except where the gauging is located.
