摘要： A panel testing apparatus for measuring the curvature of an inner surface, the thickness of an edge portion, and the thickness of a center portion of the panel comprises a lifting device for accepting and transporting the panel to a testing position, and a panel supporting device for maintaining the panel in a predetermined position during testing. The apparatus comprises a panel inner curvature measuring device, edge thickness measuring device, and a center thickness measuring device, each of which using one or more linear variable differential transformers for the purpose of providing panel measurement data. The apparatus further comprises a studpin leveling device for measuring the burial depth of studpins within the panel and simultaneously leveling the studpins to the same height, and a studpin position measuring device for measuring the horizontal and/or vertical placement of the studpins within the panel, each of which using one or more linear variable differential transformers for the purpose of providing studpin measurement data.
