A load cell is a device used to measure weight or force. It converts the force exerted on it into an electrical signal, which can then be read by a scale or computer. Load cells are commonly found in various applications, such as weighing scales, industrial machinery, and even in vehicles to monitor load distribution. These devices come in different types, including strain gauge, hydraulic, and pneumatic load cells, each suited for specific tasks. They are essential in industries like manufacturing and logistics, where accurate weight measurements are crucial for safety and efficiency.
