Todays paper machines require an impressive amount of data collecting and huge papermaking expertise to run at their peak efficiency. Recent instrumentation technology from Cristini Diagnostic Systems allows real time data output for consistency and drainage in the most critical parts of the forming section even where access is limited for safety reasons. The direct measurement of water on the wire provides visibility into both drainage rates and the effects of stock preparation raw material quality chemicalsadditives as well as former set-up. This information can help improve product quality forming fabric performance and process efficiency while reducing the energy consumption of the forming pressing and drying operations. Changes on the table are measured in real time and these measurements can then be used in a variety of methodologies. The logic of the Cristini planar microwave sensor technology is typically oriented to provide an easy integration into other elaborate systems DCS MCS QCS found in the control loop of the papermaking process. applIcatIon baSed on the mIcroWave technology The story began over 25 years ago and lead to the actual substitution of the formIng conSIStency monItorIng By luca canali Development Leader Cristini Diagnostic Systems Italy giovanni cristini Vice President Technology Cristini S.p.A.

This new and innovative application based on microwave technology has changed the principles of the consistency measurements and is setting a new standard. After the important success of the worlds first portable microwave consistency metre Cristini Diagnostic Systems has developed FiberscanFIX Fig.1 fixed point andor traversing measurement sensors that allow direct connections to the machines own DCSMCS systems for data analysis. Fast Fourier Transform FFT capabilities are included with this line of sensors providing near instantaneous read-out of pulsation or vibration issues. The 247 unmanned data collection in the forming section has led to impressive results of process control and paper quality improvement. this new and innovative application based on microwave technology has changed the principles of the consistency measurements and is setting a new standardfigure 1.
