In a four-load-cell system, each load cell must measure one-quarter of the total load. This type of configuration is more common in industrial scales. Here, each load cell is mounted at each corner of the platform.
The output terminals of all the four load cells are connected to a summing box, where signals from all the load cells are trimmed and combined into one single output. The summing box will make necessary adjustments whenever the location or orientation of the load changes. This final output is then sent to the strainmeter or a handheld display for final measurement.
