A torque sensor is a device that measures the twisting force, or torque, applied to an object. It is commonly used in various applications, such as automotive testing, industrial machinery, and robotics, to ensure proper functioning and safety. By providing real-time data on torque levels, these sensors help engineers and operators make informed decisions. Torque sensors can be categorized into different types, including strain gauge sensors, magnetostrictive sensors, and optical sensors. Each type operates on different principles but serves the same purpose of accurately measuring torque. This information is crucial for optimizing performance and preventing mechanical failures.
