The Tension Controller Measures The Tension Of The Web Through A Tension Sensor

The tension controller measures the tension of the coil through a tension sensor, and then the controller automatically adjusts the clutch or brake to control the tension of the coil. This method is the full closed-loop control of tension, which can reflect the change of tension in real time, so the control accuracy is the highest.

The tension controller is designed for the printing press. It has two outputs, which can realize pre-start and automatic shaft change for the double-station winding of the printing press, and it has the function of automatic receiving and cutting output.

The tension controller can measure the actual tension of the coil, and automatically adjust the exciting current of the clutch or brake after PID calculation according to the set target tension and the measured tension to control the tension of the coil. The fully automatic tension controller has extremely high tension control accuracy, and is suitable for occasions with high requirements for tension control accuracy.

The tension controller consists of a high-speed microprocessor and a high-power switching power supply. It can work in three modes: constant current, constant voltage, constant power (constant torque). It can automatically compensate the thermal attenuation of the clutch / brake, and the torque output is stable and reliable.

Tension controllers can be used in all areas related to coil handling
Tension controllers produce products in the form of belts and threads in the industrial control industry. Tension controllers often need to control tension to meet production requirements. Tension controllers are an instrument that control such tensions. The tension controller can set the tension value required to be controlled. After comparing and processing with the tension sensor feedback signal, it is output to the brake clutch control. The tension controller can also be used in all areas related to coil processing.

The tension controller is in the process of winding or unwinding, when the winding diameter changes to a certain stage, the operator adjusts the manual power supply device to achieve the purpose of controlling tension. However, the manual tension control system of modern gravure printing presses has been basically eliminated, and only exists as an operating mode in a closed-loop automatic tension control system.
