Introduction
Suspension mounting with tension S-beam load cells is often used
for light to medium vessels where an existing overhead structure
may be used to suspend the vessel.
General Mounting Principles
Figure 2-37 illustrates the correct way to apply load to an S-beam
load cell.
1) The surface from which the cell is suspended should be rigid
and provide minimal deflection under loads.
2) The entire suspension should be as long as possible with the
load cell placed approximately at the center.
3) The center line of the top and bottom rods should pass
through the load cell’s load holes. The center line through the
assembly should be vertical.
4) The load cell cable should emerge from the fixed end of the cell
so that it does not affect accuracy.
5) The extremities of the suspension should be attached to the
structure and vessel in such a manner that they are free to
move. At a minimum, use spherical washer set as illustrated
in Figure 2-37.
6) Use a suitable hardware assembly such as eye bolts or the
ITCM system at the load cell to minimize the transmission of
extraneous forces.
