THE NEW-GENERATION OF THE BFI FLATNESS ME ASURING SYSTEM

Demands on the measuring accuracy of flatness measuring devices. Corre lation between the required measuring accuracy and the strip tensile s tress in various application ranges. Necessary reduction of the measur ing zone width. Development of a flatness measuring roll with solid ro ll body and piezoelectric sensors. Digitization of the measuring signa ls and contactless transmission from the roll to the stator. High meas uring accuracy and high resolution over the strip width of the new mea suring system. Trouble-free transmission of the force measuring signal s and possibility of using the system in all types of steel and alumin ium strip mills.
