WEIGH MODULES Double-Ended Beams
RL1600 Modules
These assemblies are suitable for medium- to heavy-capacity
applications because of the inherent strength and stability of the
double-end center-loaded cell, supported at both ends on pins. The
modules are self-checking in all directions while allowing some
freedom for the vessel to expand/contract in a single direction by
sliding on the mounting pins. The modules also offer lift-off
protection to prevent the tank from accidental tipping.
The RL1600 module is a rugged and economical module for use
where minimal expansion/contraction movement is expected. Pre-
cise alignment is critical with these modules, as there is little room
for misalignment with the clamping yoke that holds the load plate
to the load cell. Load cell replacement requires raising the vessel
nearly an inch to remove the cell.
The 1600 series modules are available in either fabricated mild
steel or cast iron, and in fabricated stainless steel where extra
corrosion protection is required.
Allowable Movement
Figure 2-20
This module allows limited movement in a direction perpendicular
to the longitudinal axis of the load cell.
Construction and Features
1) A rigid base plate with four cross-drilled uprights to support
the pins holding the load cell.
2) A chair clamps around the load cell’s center. This arrange-
ment allows the cell freedom to slide laterally a short distance
on the pins, as indicated in Figure 2-20.
3) The module is self-checking in all directions.
4) It is available in mild steel and stainless steel construction in
capacities from 1,000 lb to 75,000 lb, and in cast iron from
1,000 lb to 25,000 lb. It may be used with RL75016 load cells
in alloy steel or stainless steel.
