Rice Lake RL9000TWM-HT Series - Manual (Page 3)

1. Introduction
The RL9000 TWM Load Cell Mount provides an extremely accurate method for weighing
medium and large capacity tanks and hoppers that are subject to large thermal expan-
sion/contraction or vibration forces. The design uses a low profi le shear web load cell
(350Ω bridge) and transmits the load via a spherical washer on the load-bearing hub
of the cell. This design is very effective in providing for thermal expansion/contraction
with little friction.
In most applications, the assemblies are self-
checking and held captive with no need for check or
stay rods, making this mount a good choice for most
vessel weighing applications. The shear web design
eases load cell installation and replacement without
the need to raise the weighed vessel a large amount,
which could disturb piping and other connections.
The RL9000 TWM is available in stainless steel, in capacity sizes from 1,000-450,000
lb. The RL9000 TWM utilizes a welded-seal stainless steel load cell.
The installation should be planned by a qualifi ed structural engineer. Each installation
is unique, and this manual is meant to serve only as a general guideline for installation.
The RL9000 TWM is capable of weighing accurately with as much as a 3˚ non-parallel
loading. The RL9000 TWM module offers 100% sideload, 100% uplift and 300%
overload protection.
