Gicam weight indicators are weight indicator devices connected to load cells. We have multifunction displayers for weighing and dosing, for bridge weighing, with load limiter. Portable displayers are available in comfortable briefcases. We have panel mounting, portable, DIN and OMEGA bar mounts, analog indicators and touch screens indicators. IP65 products are available with dust protection. Gicam indicators support industrial communication protocols like PROFIBUS, PROFINET, MODBUS and more.

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
