The process which is used to install a load cell or multiple load cell system tends to vary significantly depending on the load cells, application, loading axis, environment and other factors too. But, there are some universal practices that can be followed to greatly eliminate the risk of equipment damage and mechanical error when installing the load cells.
Tips to install load cells
Each and every load cell and application is different. Hence, you need to perceive each load cell removal and install it separately from other load cells you are working with. Below are listed some tips for installing load cells.
- Always pay heed to the load cell datasheet to make sure that the accurate wiring color code is in use.
- Load cells must always be kept on strong and stable structures. When you are mounting the assemblies, they must compensate for support surfaces if they are misaligned
- When it comes to multi load cell systems, each and every load cell must be kept on the same horizontal plane. So, always make the use of accurate mounting assemblies for height compensation.
- Make sure that all mounting and loading services are kept clean and free from dirt and debris.
- The loading surface must always be kept perpendicular to the loading axis to prevent side, bending or torsion forces.
- Prevent dropping or sudden impact while you are installing load cells. Any kind of damage can also be caused in a loss of accuracy.
- Never cut or lengthen the load cell cable. The load cell calibration is determined on the basis of the cable length during calibration.
- Whenever available, always make the use of proper mounts and assemblies equipped with overload limiters and stops.
- Every load cell and system must be duly protected against tipping and shifting associated to vibrations, seismic conditions, windy conditions, and stability of the support structure.
- Every load cell and the entire system must be properly grounded.
- Keep the welding at bay with the already installed load cells. If you cannot, then place the welder ground clamp near to the required welding point to avoid sending current via the load cell body.
- Load cells must be kept away from excessive moistures at all costs. Always use waterproof sheaths and joints to shield the cables from corrosion. This is not applicable to specialized water proof and submersible systems.
