Additional lift-of protection

EN-7
-
The supporting structure of the scale (i.e. the load cell support) and the vessel must
be stable enough to withstand the speciied loads, be horizontal (water level!) and
lat.
- Vessels should preferably be supported by 3 load cells (see igure).
- Transverse and/or horizontal forces and torques exceeding the permissible limits are
disturbances which can generate measuring errors and, in the worst case, may
damage the load cell.
- If the object to be measured is constrained properly, damage and measuring errors
can be prevented without afecting the required space for movement in the direction
of the measurement.
Consideration should be given to the fact that thermal expansion and contractions
may constrict the required space for movement of the object to be weighed and
could thereby lead to signiicant falsiication of the measuring results.
Therefore, special attention should be paid to the design, arrangement, and
condition of the constrainers.
For safety reasons, a lift-of protection has to be generally provided on vessels. This can
be constructed separately or additionally installed in the mounting kit (see Chapter 11.2.1).
For this purpose, the simplest version requires the following components:
- 1× threaded bar (1)
- 3× nut (2)
- 1× washer (3)
