摘要： A sensor imbedded rolle (40) for detecting changes in properties of a material and a measurement apparatus including a fixed impedance element coupled in series with a variable sensor imbedded roller (40) between an input signal and a reference potential is described. The sensor (41), which includes an electrode configuration, is embedded into a roller (40) such that when the roller rotates the sensor contacts the material being measured and the sensor's 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 (40) can be placed in a sheetmaking machine to measure the pre-formed and post-formed paper product.

摘要： Significant improvements in papermaking control can be achieved by employing an array of sensors that are positioned underneath the wire of the machine to measure the conductivity of the aqueous wet stock. The conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information which can be used to monitor and control the quality of the paper sheet produced. Because CD water weight profile is obtained practically instantaneously, the MD and CD variations are essentially decoupled. Quality improvements to the sheet fabricated will be achieved by providing fast control of the actuators on the machine and by tuning components on the machine to eliminate the sources of variations. Further, the dry stock weight of a sheet of wet stock that is resting on a water permeable moving wire of the papermaking machine can be made employing a water weight sensor element that is positioned adjacent to the wire and that generates signals indicative of the water weight of the sheet of wet stock on the wire. Moreover, the moisture level cross-direction (CD) profile of a sheet of material that is produced can also be measured.

摘要： System and method for producing paper that employ an apparatus for measuring electrical characteristics of a fibrous composition. The apparatus comprises a plurality of conductivity (or resistance) detectors (26) each comprising a sensor that is sensitive to the conductivity (or resistance) and the proximity of the material (e.g., fibrous composition) to the sensor. Measurements from the apparatus relate to the zeta potential of the fibrous materials in the composition. The zeta potential profiles corresponding optimized configurations of the sheetmaking process can be employed to monitor and control the process.

摘要： A system of providing on-line turbulence measurements in a papermaking machine. The measurements are used to perform on-line adjustments to turbulence-inducing and adjusting elements in the papermaking machine to optimize final sheet product quality. Turbulence measurements are obtained using water weight sensors (23) in the wet end of the papermaking machine, specifically, under wire water weight measurements. Water weight readings are correlated to turbulence intensity levels. A turbulence processing sensor (25) sorts accumulated water weight measurement readings into intensity level intervals to obtain turbulence measurements or a turbulence profile. The trubulence measurements or profile is provided to a machine element controller (26) which uses the measured turbulence information and target turbulence information to generate control signals. Water weight sensors can obtain independent machine direction (MD) and cross machine 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 system and method for producing paper product from a wetstock solution using a sensor for sensing resistive impedance changes of the wetstock on the support web of the system. The resistive impedance changes are used to measure, for example, the water weight of the wetstock. The system includes a fixed impedance element coupled in series with a sensor portion between an input signal and ground. The sensor portion includes two electrodes with the wetstock passing between and in close proximity to the electrodes. The sensor exhibits a variable impedance resulting from changes in the physical characteristics of the wetstock. The fixed impedance element and the variable impedance of the sensor portion form a voltage divider network such that changes in impedance of the sensor portion result in voltage changes which are measured, converted to impedance changes of the wetstock, and related to water weight of the wetstock.
