Best Practices can be Quantified on Grade Changes, Energy Saving Projects, and Process Control Parameters, PaperCon2017

At PaperCon 2016 studies were introduced that showed potential process control benefits that can be realized on paper machines equipped with the traversing devices that permeability, water content, and temperature.  These scanners provide detailed data analysis including 3D mapping of the press felts in several modes, and Fast Fourier Transformation (FFT) analysis of the incoming data to show pulsation and vibration issues before they become problematic on the felts, and provide a tool to the maintenance department, negating the need for “run to failure” mode. 

These scanning units can now be supplemented with lower cost fixed-point instruments, which accurately measure water content of the fabric, the fabric and sheet; or, the sheet itself.  This ability to measure consistency in press section applications, with +/- 1 gsm accuracy, is now possible. All these instruments contain planar microwave sensors which can measure the moisture of the sheet, the forming fabric, the felt, and the felt and sheet at any point on the machine where the small measuring head can be mounted.
