MOUNTING OF THE LOAD CELL

General precautions to be followed in the installation and assembly of load cells:

  • Follow the direction of application of force on the load cell
  • Do not exceed the limits of the temperature as indicated in the data sheet
  • Do not remove labels from the load cell
  • Adequately protect the cables with sleeves or channels
  • Carry out on each load cell a ground connection with suitable cable, shunt on mounting accessories
  • Do not carry out any welding on the mechanical structure after mounting the load cell
  • Avoid or reduce to a minimum level any mechanical constraints between the rigid structure and the weighing structure to avoid error in weighing and return to zero
  • In case of vibration or dynamic loads product the load cells with puffers / shock absorbers
  • Protect load cell from any dust accumulation with any appropriate means
