Load cell mounting
General guidelines for installing and mounting load cells:
- Respect the direction in which forces are applied to the load cells
- Do not exceed the temperature limits shown on the rating plate
- Do not remove the labels from the cells
- Protect cables properly with sheaths or cable ducts
- Connect each cell to earth with a suitable cable, bridging the plates of the mounting accessories if necessary
- Do not weld on the mechanical structure once the cells are in place
- Avoid or minimise mechanical constraints between the fixed structure and the weighed structure, to prevent weighing errors and zero return problems
- When vibrations or dynamic loads are present, protect the cells with anti-vibration mounts
- Protect the cells from dust build-up with suitable covers
