The procedure below defines the main considerations involved in designing a load cell
installation.
1. Check load cell data so that environmental demands are met.
2. Calculate forces; vertical, horizontal and axial (cross directional).
3. Size and orientate load cell so that the guidelines below are met:
a. Try to achieve a measured value no less than 10% of web tension, in the load cell
measurement direction!
b. Select load cell size so that it is loaded as close as possible to its nominal load! Do
not dimension Force component of Tension in measuring direction, FR, for less than
10% of the load cell nominal load!
c. If the span between maximum and minimum tension in the process is large, select
load cell so that the maximum tension will be in the load cell extended range (when
applicable)!
d. The measured force component of web tension is recommended to be at least 30% of
tare force component (roll weight) acting in load cell measurement direction. The
reason for this recommendation is load cell signal stability, especially when the
system operates in a large temperature span.
This means that if FRT < 1/3 of Fnom, FR should be at least 10% of Fnom.
For larger FRT, lowest FR is recommended to be at least 30% of FRT.

The instructions below apply to a typical mounting arrangement. Variations may be allowed,
provided that they comply with the requirements in Appendix B.4.
1. Clean the foundation and other mounting surfaces.
2. Fit the lower adapter plate to the load cell.
Tighten the screws (included in delivery) with a torque wrench to 24 Nm (18 ft.-lb).
3. Fit the load cell and the lower adapter plate to the foundation,
but do not fully tighten the screws.
4. Fit the upper adapter plate to the load cell.
Tighten the screws (included in delivery) with a torque wrench to 24 Nm (18 ft.-lb).
5. Fit the bearing housing and the roll to the upper adapter plate,
but do not fully tighten the screws.
CAUTION
When mounting bearings or other adjacent details to adapter plates, screws must
not protrude into the load cell. The load cell can be damaged by an excessive
applied force.
