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
