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 orient load cell so that the guidelines below are met:
a. Try to achieve as large portion as possible 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 FR
Calculation procedure:
1. Horizontal or inclined mounting?
2. Calculate FR and FRT, see Section E.5, Mounting Alternatives, Calculating Force and
Calculating Wrap Gain.
3. Use the following equations:
FR for single load cell =
FRT for single load cell =
FRtot for single load cell = FR for single load cell + FRT for single load cell
where:
L = Distance between load cell centerline and the opposite bearing centerline
a = Distance between tare force center and load cell centerline
b = Distance between tension force center and load cell centerline
