Abstract: Areal weight or thickness of a moving coated metal sheet along its entire cross directional width is derived by correlating thermographic image data to online, scanning basis weight measurements. Thermal imaging camera captures thermal images of a heated moving coated metal sheet material along a cross direction at a first position along the machine direction to generate sequential temperature profiles. Scanning beta gauge measures the areal weight of the moving coated metal sheet downstream at a second position. An infrared temperature sensor also measures the temperature of the moving coated metal sheet which is at a lower temperature at or near the second position. The temperature differential between the cross directional thermographic image data and the latter infrared temperature is a function of the basis weight. Basis weight measurements from the beta gauge is used to extrapolate cross directional basis weight data.
