If the actual load cells are used during installation, extreme care must be taken to prevent
overload damage.
• A tank or hopper weighing several tons can exert huge forces when dropped only a
fraction of an inch.
• Dummy load cells can be used during installation.
The neoprene mount of the RL50210 TA/65059 compresses as load is applied, making
the mount particularly suitable for applications involving very minor shock loading.
• It is not recommended for vessels with attached piping because the added downward
deflection of the vessel as it is loaded makes it difficult to design a piping system with
the required degree of flexibility.
Do not install weigh modules until all welding is completed.
• The heat generated by the welding current passing through a load cell can damage
the adhesive holding the strain gauge to the body.
• If possible, use a dummy load cell when welding to maintain finished height.
• If welding is unavoidable after load cell installation, connect the ground in such a way
that the current does not flow through the load cell.
• Protect the load cell and cable from weld splatter.
Example: if welding on the mount top plate, the ground must be connected to
the vessel, not to the mount base or support structure.
The arrow on the load cell should point in the direction of the load.
Use only hermetically sealed load cells in washdown applications.
• Environmentally protected load cells are not suitable 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 weighing assembly is
recommended
• Proper drainage is necessary so the weighing assembly is not standing in water
All support points should be equally stiff so that they deflect by the same amount as the
vessel is loaded.
