Selection of the weighing cell(s)
The following data are required to determine the capacity of the weighing cell:
• Scale capacity – Usually corresponds to the heaviest weighing sample that is to
be weighed using the weighing system.
• Preload – Contains the total weight of all the parts that lie on the weighing cell.
These include the top section of the weighing platform, the weighing pan and all
the assemblies, such as a roller conveyor, weighing vessel etc.
• Total zero setting range – Consists of the desired activation zero capturing range
(+18/–2 % or +/–2 %) and the zero setting range available to the user through
key (2 %). The total zero-set range thus amounts to either 20 % or 4 %
the
of the scale capacity.
The addition of the scale capacity, preload and total zero setting range results in the
required capacity of the weighing cell. It is advisable to include an additional safety
margin in order to avoid overloading of the weighing cell.
.
Total capacity of the weighing cell(s) = Scale capacity + Preload + Total zero setting range + Safety margin
In the case of systems with several weighing cells divide the determined total
capacity by the number of cells in order to determine the capacity of the individual
cell. A sufficiently large safety margin is particularly important if a strong load is to be
expected in the corner areas of the scale so that the load is no longer distributed
evenly amongst all the cells.
In the case of systems with a lever mechanism divide the determined total capacity
by the transmission ratio of the lever mechanism in order to determine the capacity of
the individual cell.
Take the following further parameters into consideration when selecting the weighing
cell(s):
• The smallest desired display step
• Requirements for admissibility for certification, if necessary
• Number and type of the weighing ranges
• The approval for hazardous areas in the case of explosion protected weighing
systems
