In the process of tension control, PFVO 142 3BSE023732R1 analog voltage amplified by real-time sampling can be converted into corresponding digital quantities using a 12 bit high-performance ADC. The digital signal input from the angular velocity detector is coupled to the controller through a photoelectric isolator. There are two types of angular velocity detectors, one is called proximity switch and the other is called encoding switch. During the rotation of the roller, the teeth on the roller cause them to have high and low level digital changes, achieving the measurement effect. For the convenience of users, a good human-machine interface is provided here. Firstly, an input method combining buttons and encoders is provided; Secondly, the measured tension and set tension can be displayed on the LCD, and the digital tube can also display the current output percentage.

In the process of tension control, PFVO 142 3BSE023732R1 tension execution unit is magnetic powder, which is divided into two types: one is called magnetic powder clutch, and the other is called magnetic powder brake. They are used in the process of winding and unwinding the coil, respectively. The magnetic powder is connected to the receiving and releasing drums through a universal coupling, and is filled with fine ferromagnetic powder.
