1 Safety Instructions
The PR 6201 with the relevant mounting kits must be used only for the weighing applications for which it
is intended. The dimensions of all mounting and structural components must be calculated so that
sufficient overload capacity is ensured for loads which may occur while taking the relevant standards into
account. In particular, upright weighing objects (vessel etc.) must be safeguarded against the weighing
installation turning over or being shifted, thus eliminating danger to humans, animals or goods even in the
case of a break in a load cell or mounting element.
Installation and repair work must be carried out only by qualified personnel.
2 Design Recommendations
2.1 Positioning of Load Cells and Constrainers
* do not constrain this position
The supporting structure of the scale (i.e. the load cell support) and the vessel must be stable enough to
withstand the maximum design loads, horizontal (check with spirit level!) and flat. Vessels should preferably be
supported by 3 load cells, platforms and weigh bridges by 4 or 6 load cells (see figure).
Parasitic forces, horizontal forces and torques are disturbances which can generate measuring failures and
in case of exceeding the specified limits may damage the load cell.
An accurate constraining of the object prevents of damages and measuring errors without affecting the
required space for movement. Therefore special attention should be paid to the design, arrangement and
condition of the constrainers. Thermal expansion and contractions of the object are to be taken into
account which may affect the required space for vertical movement and thus influence the measuring
results.
