14.8 RL1900 Modules
The RL1900 module is similar in design to the RL1800, but
accommodates slightly more lateral movement than the
RL1800. See Figure 14-10.

Construction and Features
1. A base plate and spacer support the load cell.
2. A trunnion block is suspended below the free end of
the load cell. It is attached to the load cell using a
bolt which passes through the clearance load hole
and is retained by a nut at the top of the cell. Two
spherical washer sets are used; one sits between
the bolt head and trunnion block, the other sits
between the nut and the top of the load cell (which
is counterbored to accept the washer set).
3. A chair arrangement is attached to the trunnion
block through pivot screws; the load is applied to
the top plate of this chair. This arrangement allows
the chair to move in the directions indicated in
Figure 14-10.
4. This module allows slightly greater lateral movement
than the RL1800 by virtue of the fact that the
suspension bolt passes through a clearance load
hole in the cell and has spherical washer sets at the
top and bottom.
5. Because the load is suspended from the underside
of the cell, the module is self-centering; that is, after
a disturbance temporarily moves the top plate
laterally, it will tend to return to its original position
under the influence of gravity.
6. The module provides lift-off protection and lateral
restraint.
7. The module provides height adjustment.
8. The RL1900 module is available in capacities from
1,000 lb to 10,000 lb in stainless steel.
9. This module can accommodate both environmentally
protected and hermetically sealed load cells—the
RLSSB, the HBM SB3 and the Vishay RTI SSB.
Typical Installation

14.9 Paramounts ® HS and Paramounts ®
EP
The versatile Paramounts vessel weighing system consists of
three different modules, which together make a complete
system of fixed and sliding modules with single-ended SB4,
SB10 and SB5 load cells. This unique system allows a vessel
to expand freely on sliding modules, yet the system is
self-checking. All models are available in capacities to 22,500
lb.
