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