Constructions of compact systems
Many years of
MRC
’s experience in producing balances with high resolutions ( max 30 mln
divisions) analyzing solutions of competition and our own research and development have resulted in
creating a new solution, being a compromise in the field of measuring mechanism construction –
compact system.
The first attempts of such solutions started many years ago, however only after the technology was
fully developed the system could be used in most of
MRC
’s balances.
The fundamental principle of compact system is separation of components that require precision
in their manufacturing and assembling from the body unit of the mechanism, in which, only the base
surfaces are significant and possible to manufacture using milling technology with NC machines.
There two elements from traditional technology used in compact system:
string
– connecting the unit of
measuring lever with parallelogram and the bearing of measuring lever.
These elements have the strongest impact on indication errors such as: linearity, hysteresis,
zeroing, and using special materials (stainless steel, beryllium bronze) undoubtedly improves their quality
and resistance against overload.
This solution eliminates basic problems connected with quality and repeatability of elements used
for manufacturing traditional weighing mechanisms, and at the same time lowers production costs and
enhances the quality. Bearing the above in mind, one can make a practical comparison between the
construction of a balance and other solutions used in constructions of machines for example a
combustion engine used in cars.
