4.6 Protection against explosion
To ensure that no force components occur in the measuring direction, you must install guide
elements at precise right angles to the effective direction of the load cells.
Three guide elements are sufficient to statically fix a weighing platform or container.
NOTICE
Weighing errors
With four guide elements, there is a risk of the guide elements mutually tensioning, which in
turn induces weighing errors. If you nevertheless want to use four guide elements, the
guide elements must be installed with a sufficient amount of play.
Ensure that the guide elements to be used comply with the principles applicable to weighing
technology.
