Abstract:
1. A sensor system for measuring a thickness of a flat material that is moved relative thereto, comprising: a first sensor device for measuring the thickness of the flat material; a device for generating an air cushion between the flat material and at least one side of the first sensor device that faces the flat material, the first sensor device including in a region of the air cushion, surface sections that include at least one of a porous material and a material that is provided with micro-holes; and a second sensor device for detecting damage or holes in the flat material, the second sensor device being disposed relative to the first sensor device and the flat material so as to detect the damage or holes in the flat material before the damage or holes reach the region of the air cushion due to relative movement between the flat material and the first sensor device.
