6. When possible, use only “hermetically sealed” load cells in washdown
applications. “Environmentally protected” load cells are not suit-
able for such applications and will be damaged. If tanks and surrounding
equipment are frequently steam cleaned or if the load cell is subjected to
direct washdown, a protective shroud for the weigh module is recom-
mended. Proper drainage is necessary so the weighing assembly is not
standing in water.
7. All support points should be equally stiff so that they deflect by the same
amount as the vessel is loaded.
8. Never expose the load cell or mount to excessive forces as this might
seriously jeopardize personal safety. If major load movement is antici-
pated, stay rods should be used to restrain the platform or vessel. Multiple
load cell applications require the mounts to be installed on the same
horizontal plane and level. Never use mounts or load cells to pull uneven
surfaces together; use shim plates when appropriate. Perform routine
maintenance to assure long-term reliability and performance. This in-
cludes a careful physical inspection of bolts and parts, as well as the
removal of any material or debris build up from the load cell and mounting
fixtures. Serious damage can occur if mounting systems do not function
correctly.
2.2 Installing the RLC
The RLC self aligning mount should be installed without the load cell or dummy
being present, while observing the following guidelines:
1. Assemble the self aligning mount as shown in the assembly drawing,
taking care that the top and base plates are correctly aligned (the RLC does
not lie in the center of the base plate and so care should be taken to ensure
that the upper bearing locating hole is correctly aligned).
2. The top plate (3) should be locked at Dimension A, as shown on the
dimensional outline drawing, using the M12x60 or M16x70 socket head
screws (12) and the M12 or M16 nuts (10).
