A load cell is a device that converts a mass signal into a measurable electrical signal output. Its performance largely determines the accuracy and stability of electronic weighing instruments; consequently, it is often referred to as the "heart" of the weighing system.
For instance, aluminum alloy cantilever load cells are suitable for electronic price-computing scales, platform scales, and bench scales; steel cantilever load cells are used in electronic belt scales and sorting scales; steel bridge-type load cells are suitable for railway scales and truck scales; and column-type load cells are used for truck scales, dynamic railway scales, and high-capacity hopper scales. Load cells are primarily applied in various electronic weighing instruments, industrial control systems, in-line process control, safety overload alarm systems, and materials testing machines. Specific examples include electronic truck scales, platform scales, forklift scales, dynamic axle load scales, crane scales, price-computing scales, steel-weighing scales, railway scales, hopper scales, batching scales, and tank-filling scales.
