A load cell is a type of sensor used to measure weight or force. It converts the mechanical force applied to it into an electrical signal, which can then be measured and displayed. Load cells are commonly used in scales, industrial applications, and various types of weighing systems. These devices typically consist of a metal element that deforms slightly when weight is applied. The deformation changes the electrical resistance of the material, allowing for precise measurements. Load cells are essential in many fields, including manufacturing, transportation, and medical equipment.
