Torque Screwdrivers demonstrate a high degree of intelligence and precision in monitoring and controlling torque, especially sensor-based screwdrivers, which have taken this technology to new heights. These screwdrivers are equipped with precision torque sensors, a core component that acts as the "eyes" of the tightening process, capable of real-time and accurate measurement of the torque applied during tightening. The sensors quickly feedback the torque data to the built-in closed-loop control system, which serves as the "brain" of the wrench, possessing the ability to rapidly analyze and make decisions.

After receiving data from the torque sensor, the closed-loop control system immediately compares the current applied torque with the preset target torque and adjusts the motor output in real-time based on the comparison results. This dynamic adjustment process ensures that the torque applied by the wrench during tightening remains within the preset range, neither too tight nor too loose, thereby achieving precise control of torque.
When the torque applied by the screwdriver reaches the preset target value, the closed-loop control system immediately triggers a power-off mechanism, stopping the wrench from operating. This design cleverly avoids torque overshoot, ensuring the stability and safety of the tightening process. In addition, sensor-based wrenches are usually equipped with visual tool controllers and host computer systems, providing comprehensive monitoring and recording capabilities for the tightening process.
Through the tool controller and host computer, operators can monitor key parameters such as torque changes, tightening speed, and tightening angle in real-time. These data not only help optimize the process but also provide strong support for quality control. More importantly, the recorded data makes each tightening step traceable and verifiable, ensuring that every detail of the manufacturing process meets strict standards and requirements.
Sensor-based torque screwdrivers, with their built-in torque sensors, closed-loop control systems, and visual monitoring and recording functions, achieve precise monitoring and control of torque, providing a strong technical guarantee for high-quality production in modern manufacturing.
