Figure 1-1 RL 2200 Load Cell Mounting Kit
The RL2200 Load Cell Mounting Kit provides an extremely accurate method for
weighing
mal expansion/contraction or vibration forces. The design
pression disk load cell (350Ω bridge) and transmits the load with a rocker pin 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 selfchecking and held captive with no need for check
or
areas with frequent seismic activity. The rocker
pin 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 RL2200 is available in mild steel or
steel, in capacity sizes from 5,000-50,000 lb. The RL2200 is also available with hermetically-sealed stainless steel
lb to 50,000 lb.
The installation should be planned by a qualified structural engineer. Each installation
