D.6 Mounting Alternatives, Calculating Force and Calculating Wrap Gain

D.6.1 Horizontal Mounting

The PFRL 101 load cells can be mounted at any incline 
angle, 0 - 360°. However, it is recommended to minimize 
the influence of forces other than the tension to be 
measured. In most cases this means an orientation where 
the tare force (vertical) is perpendicular to the measured 
force (horizontal).
However, should the machine design require inclined 
mounting of the load cell or should the web path not give 
a sufficient horizontal force, see figure, the inclined 
mounting is permitted and the calculations are somewhat 
more complex, (see 

Section D.6.2, Inclined Mounting

).

The load cell measures the horizontal forces. The load 
cell can measure in both directions. The vertical applied 
forces are not measured and do not influence the 
horizontal measurement. There is one source of 
horizontal forces, the force from the web tension (the tare 
weight has no force component in measuring direction). 
See force calculations in figure.
Divide the total vertical force F

Rtot

 by two to get the 

required capacity of each load cell.
Do not oversize an ABB load cell for overload purposes 
as the load cell has sufficient overload capacity.

No horizontal web tension force 
applied to the load cell.
