5.1.1
Preparing the foundation/substructure
-
The foundation for the mounting kit must be horizontal (use spirit level), flat, and
rigid for the intended loads.
-
The load distribution on the available load cells must be as even as possible to
prevent overload of the individual load cells.
-
The substructure foundations/supporting surfaces for the mounting kits should be at
the same level, and the supporting surfaces of the weighing object (e.g. vessel feet)
must be arranged in parallel.
-
If soft filler layers (e.g. made from rubber or plastic material) are used between the
mounting kit and vessel and/or between the mounting kit and substructure for
vibration dampening or for temperature insulation, a load compensating plate must
be provided between this soft filler layer and the mounting kit to ensure even load
application into the mounting kit.
The design of the insulation and compensation plates depends on the respective
application.
