Which type of weigh module suspension should you use? Table 6-1 provides
guidelines for proper application.
Type of Suspension
Application Parameters
Rigid
Static or dynamic loading without thermal
expansion/contraction, piping connections, or high horizontal
shear loads.
Sliding
Static loading with thermal expansion/contraction and flexible
piping connections.
Self-Aligning
Static or dynamic loading with horizontal shear loads,
thermal expansion/contraction, and flexible piping
connections.

Self-Aligning Suspensions with Stabilizers
Self-aligning weigh modules offer the best weighing performance over the widest variety
of applications. Some weigh modules with self-aligning suspensions can be equipped
with optional stabilizer links to prevent horizontal movement transverse or longitudinal
to the load cell. The stabilizer link consists of adjustable rod end bearings that connect
the top mounting plate (load receiver) to the base mounting plate (see Figure 6-1).
NOTE: The stabilizer option is not intended to provide additional horizontal force
capacity.

There are three situations in which you would use stabilizers:
1. To stabilize a dynamic scale if weighing must take place while, for example, a
large mixer is operating.
