Patent number: 11692943Abstract: Measurement apparatus including an optical sensor, which performs repeatedly transmission measurements through moving sheet of paper or board at at least one wavelength band dominantly absorbed by water, at at least one wavelength band dominantly absorbed by cellulose. The apparatus also includes an X-ray sensor, which performs repeatedly transmission measurements through the moving sheet of paper or board with photons of electromagnetic radiation (1 keV to 10 keV). The apparatus comprises a data processing unit, which receives signals with information on intensities of the optical and X-ray radiations passed through the sheet from the optical sensor and the X-ray sensor, and determines, based on the information, all of the following of the moving sheet: the dry stuff content as a function of the cellulose mass per unit area of the sheet, water mass per unit area of the sheet and the ash mass per unit area of the sheet.Type: GrantFiled: March 29, 2022Date of Patent: July 4, 2023Assignee: VALMET AUTOMATION OYInventors: Kari Veikkolainen, Marko Toskala, Markku Mäntylä

Patent number: 8248610Abstract: One measuring part of a traversing measuring unit measures at least one characteristic of a web with a first radiation type from a plurality of measuring locations during a traversing movement at successive moments in time. At least two measuring parts of an array measuring unit measure at least one characteristic of the web with another radiation type during each traversing movement at a plurality of different moments in time by directing the measurement to a plurality of measuring locations in the web at each moment in time. A signal processing unit is arranged to estimate at least one characteristic measured by the traversing measuring unit with at least one measurement of the array measuring unit.Type: GrantFiled: March 12, 2008Date of Patent: August 21, 2012Assignee: Metso Automation OyInventors: Tero O.
