A type of scale is called the load cell (load cell) that uses a “transducer” that adapts force into an electrical output that can be measured. There are several types of these “force sensors”, load cells are the kind most normally used.

Mechanical balances

Excepting for some lab where mechanical balances need to be precision, load cells leads the industry of weighing. “Air-filled load cells” are at times used where safety and hygiene are needed, and “hydraulic load cells” are in some remote locations used, since they don’t need a supply of power. Load cells offers precisions from between 0.03% to 0.25% full scale and are suitable for nearly all industrial applications.

What are Load Cells

A load cell is a device for weight measurement on electronic scales – displaying numbers as digits. But, load cell isn’t limited to measurement of weight in electronic scales. Load cell is a submissive sensor that translates functional energy into electrical signals.


These cells use diverse operating principles:

  • Fluid pressure
  • Elasticity
  • Magnetostriction effect or piezoelectric effect


However, the load cells which are dominant are the ones based on strain gauges. The purposes for the wide adoption of load cells are their features:

  1. Linear measurements that are highly precise
  2. Little problems due to changes in temperature
  3. Small size when compared to kinds of load cells
  4. Longer operating life owing to lack of parts that move or that create friction
  5. Ease in manufacturebecause of not many components
  6. Outstanding fatigue characteristics
