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.
