Single-Ended Beams
6)
Capacities 500 lb to 2,500 lb incorporate an overload stop
under the free end of the cell.
7)
Capacities 50 lb to 250 lb accommodate an RL50210 load cell
while capacities 500 lb to 2,500 lb accommodate an RL30000
load cell.
Typical Application
These modules should be attached so their longitudinal axis aligns
with the direction of greatest expected movement of the vessel or
conveyor. On a roller conveyor, this would normally be along the
line of conveyor travel.
RL50210 TA Modules
These low-capacity modules use single-ended beam load cells in
capacities from 50 lb to 2,500 lb. The resiliency of a neoprene-
cushioned mounting pad attached directly to the cell and vessel
accommodate limited movement and minor misalignment. These
units are ideal for small tanks, platforms, and in-motion conveyor
applications where checking requirements are low. The direct
connection of the vessel to the flexible neoprene pad acts to
cushion shock loads.
Allowable Movement
Figure 2-5 illustrates the RL50210 TA module’s capability to
handle movement. The arrows indicate the various means by
which the load introduction plate can move relative to the cell to
minimize the transfer of extraneous forces.

Construction and Features
1)
The module has a large base plate and spacer washer, and the
load cell is screwed directly to the base plate.
2)
Load introduction is through a steel plate bonded to a
neoprene pad which accommodates vessel movement in all
directions.
3)
Because the module can compress vertically, it provides a
degree of protection against shock loading.
4)
Because of the neoprene pad, this module provides little lift-
off protection or lateral restraint. Also, because the neoprene
pad compresses as load is applied, this module should not be
used where the vessel has attached piping or stay rods. Loosely
fitting safety check rods may be used if required.
5)
This module is available in capacities from 50 lb to 2,500 lb in
mild steel, and 500 lb to 2,500 lb in 304 stainless steel.
