Tips:
Automatic Web tension controller is mainly composed of tension detector, high-precision A/D, D/A converter and high-performance single-chip microcomputer. The automatic constant tension controller is based on the tension measured by the tension detector and compared with the set target tension, and then automatically adjusts the D/A output through the single-chip PID operation to change the magnetic powder clutch, the brake current or the servo motor. The torque is used to achieve the constant tension of the coil, which can be widely used in various occasions where precise measurement and control of the tension is required. It has flexibility and wide applicability.
