Abstract
A caliper gauge for relatively thin moving sheet material is provided by the use of an outer ring type air bearing, flexibly supported, which is flexibly connected again to an inner air bearing carrying the magnetic measuring components. The outer air bearing (with its juxtaposed mate) tends to flatten the sheet so that minimum movement is required of the independently actuated inner air bearing. Thus, great accuracy is achieved and tearing or marking of the sheet material, such as super calendered or coated grades of paper, is avoided.
