Rice Lake Z6 Single-Ended Beam, SS Welded-seal, IP67, OIML C3 - Manual (Page 26)

22 Load Cell and Weigh Module Handbook
Construction and Features
1. IP66/68 environmental rating is guaranteed against
moisture damage.
2. Load introduction mechanism isolates load from
overloads, underloads and extreme side loads,
minimizing mechanical failure.
3. Weldless construction improves washdown
performance.
4. Integral jacking/shipping bolts offer a means to
remove the load from the load cell for quick removal
and replacement of load cell and worry-free
transport.
5. All modules come standard in stainless steel.
Typical Application
Typical applications for the Survivor 1700HE include
light-capacity micro-ingredient batching and mixing as shown in
Figure 14-4.

14.5 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 14-5 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.
Figure 14-5. RL50210 TA
Construction and Features
1. The module has a large base plate and spacer
washer, and the load cell is attached or bolted
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.
6. Capacities 500 lb to 2,500 lb incorporate an
overload stop under the free end of the cell.
7. Capacities 50 lb to 2,500 lb accommodate an
RL50210 load cell while capacities 500 lb to 2,500 lb
accommodate an RL35023 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. See Figure 14-6.
