摘要： A system and method of providing on-line turbulence measurements in a sheetmaking machine and using these measurements to perform on-line adjustments to turbulence-inducing and adjusting elements in the sheetmaking machine to optimize final sheet product quality. Turbulence measurements are obtained using water weight sensors in the wet-end of the sheetmaking machine and specifically under wire water weight measurements. Water weight readings are correlated to turbulence intensity levels by correlating ranges of water weights to intensity level intervals. A turbulence processing sensor sorts accumulated water weight measurement readings into intensity level intervals to obtain turbulence measurements or a turbulence profile. The turbulence measurements or profile is provided to a machine element controller which uses the measured turbulence information and target turbulence information to generate control signals. The water weight sensors can obtain independent machine direction (MD) and cross direction (CD) water weight measurements and consequently independent turbulence measurements can be determined so that turbulence can be controlled in both directions. Machine elements are controlled so that turbulence remains uniform across the CD and so that the MD turbulence profile is optimized to resemble a target profile.

摘要： A sensor apparatus and electrode configuration within the sensor apparatus for measuring electrical characteristics of an aqueous fibrous composition. The electrode configuration includes an elongated ground electrode and at least one segmented electrode to form an array of measurement electrode cells. The electrode configuration further includes an array of reference electrode cells formed by a plurality of reference electrodes built into the array of measurement electrode cells. The measurement electrode cells and reference electrode cells have a different sensitivity to water weight of the aqueous fibrous composition and the same sensitivity to conductivity of the aqueous fibrous composition. The measurement apparatus obtains simultaneous resistive measurements from both measurement and reference cells and determines the ratio of the measurements such that the affects from conductivity is canceled out of the measurement ratio. The determined measurement ratio is used to obtain a measurement of the water weight of the aqueous fibrous composition by using previously determined characterization data of the water weight vs. a range of measurement ratios.

摘要： A sensor imbedded roller for detecting changes in properties of a material and a measurement apparatus including a fixed impedance element coupled in series with a variable impedance sensor imbedded roller between an input signal and a reference potential (e.g. ground) is described. The sensor, which includes an electrode configuration, is imbedded into a roller such that when it rotates it comes in contact with the material being measured and its impedance varies. The variable impedance of the sensor relates to changes in property of the material being sensed which can then be related to changes in other physical characteristics of the material such as weight, chemical composition, and temperature. Sensor imbedded rollers can be placed in a sheetmaking machine to measure the pre-formed and post-formed paper product.

摘要： A system and method that combine an array of fast under wire water weigh sensors with a scanning system provides an accurate measurement of the entire sheet down to 1 in. by 1 in. resolution. Because CD profiles are obtained instantaneously, MD and CD variations are completely decoupled, even if CD profiles are taken at longer intervals apart. The technique allows monitoring the basis weight of a sheet of material that is formed in a process that employs a de-watering machine that includes a water permeable moving fabric supporting wet stock and a dry end which technique includes the steps of: a) positioning an array of water weight sensor elements (array) underneath and adjacent to the fabric wherein the array is positioned in a cross direction to the moving fabric; b) positioning a scanning sensor at the dry end to measure the dry basis weight of the sheet of material; c) operating the machine and measuring the water weights of the sheet of material with the array and measuring the dry basis weight of the sheet of material with the scanning sensor at the dry end; d) developing a functional relationship between water weight of the sheet as measured by the array and the basis weight of the sheet which is formed after being substantially de-watered; end; and e) periodically, adjusting the functional relationship using readings from the scanning sensor to compensate for variations due to process parameters. The technique can further include the step of correlating positional readings of the scanning sensor with measurements from the corresponding element in the array to obtain separate calibration for each individual element of the array and step e comprises adjusting the functional relationship obtained in step d and the calibration obtained in to compensate for variations due to process parameters.
