Since 5000 BC, equal arm scale has been used for weighing. The other weighing method is spring scale. In spring scales, there is a pointer attached to spring and this pointer is used to display weight. The advantage of such scales is that they do not require any standard mass after calibration. In terms of repeatability and reliability, selecting the spring material appropriately, setting the spring sufficiently are important for the indicator to answer linearly.
Load Cell, which is subject to our work, is another method for weighing. The best transducer to display the weight on the screen is load cell.
Load Cell based weighing indicators or shortly electronic scales are like spring scales technically. Steel and aluminum is used as spring component, however the material is formed in different ways, which are convenient to measure. (Even if the spring component of a load cell is not similar with a spring, it is same in principle.)
Load cells are strain gage based transducers. Strain gages are electronic structures in various sizes and forms, which are used to analyze static and/or dynamic resistance of a system or detached structure. In commercial load cells, strain gage in 4 or 5 different sizes and forms is used (Special strain gages that are produced for analysis of various composites, marble, ceramic, glass and concrete etc. are off topic/)
Load cell is a detached structure, whereas weighing is a static measurement in general. It works on just a single axis, since it is applied in weighing. (Weight is formed because of a mass gravitated by the world with acceleration and this gravity changes depending on where you are.) Another name for it is transducer. Force is gotten by multiplying mass with acceleration. Weight is equal to gravity force of a mass in ground-vertical axis.
