METHOD AND DEVICE FOR MEASURING THE AMOUNT OF COATING ON A MOVING SUBSTRATE |
摘要 |
The invention relates to a method and a device for measuring the amount of coating on a moving substrate. Reflection measurement is used in the invention for measuring the properties of a coating (4a). The amount of calcium carbonate in the coating is measured by measuring an absorption peak of calcium carbonate at a wavelength of about 3.95 micrometers and/or the amount of kaolin is measured by measuring an absorption peak of kaolin at a wavelength of about 2.7 micrometers.
