A force sensor is a device that measures the amount of force applied to it. It converts the mechanical force into an electrical signal, which can be read and interpreted by various systems. These sensors are commonly used in applications such as robotics, automotive testing, and industrial automation to monitor and control forces in real-time. Force sensors come in different types, including strain gauge, piezoelectric, and capacitive sensors, each with its own method of operation. They are essential in ensuring safety and efficiency in machines and structures by providing accurate force measurements that help prevent overloads and failures.
