Rectangular load cells PFVL 141V for mounting under the lower back-up roll bearing housing There must be a sufficiently large flat surface on the lower part of the roll stand to allow the installation of the load cell under the lower back-up roll bearing. This arrangement has the advantage that there is no need to pay particular attention to the load cell during roll change. See also our offer regarding Load Cell Packages on the next page. The load cell can be adapted to the required dimensions, and the length is chosen as a multiple of 30 mm. For load cells longer than 900 mm, the chosen...
