Pressductor PillowBlock Load Cells, Horizontal Measuring PFTL 101, User Manual
CAUTION
During this operation it is possible to over load the load cells if the operation is done not careful
enough, especially if the roll is heavy.
The most critical load cells are naturally the PFTL 101A-0.5 kN and PFTL 101B-2 kN.
Applications with inclined mounting are most critical.
6. Adjust the load cells so that they are in parallel with each other and in line with the axial direction
of the roll. Tighten the foundation screws, see
ment of Load Cells page 21.
7. Adjust the roll so that it is at right angles to the longitudinal direction of the load cells.Tighten the
screws in the upper adapter plate, see
Load Cells page 21.
