Strain gauge torque sensors are a type of torque sensor that uses strain gauges to measure the torque applied to a shaft. Strain gauges are devices that change their electrical resistance when deformed. By measuring this change in resistance, the strain (and thus the torque) can be determined. These sensors are known for their high accuracy and reliability and are widely used in various industries.
