PFTL101BE 20KN 3BSE004214R1 ABB 张力控制器

张力控制器是一种控制仪表，通常由单片机或一些嵌入式器件及外围电路开发而成。在工控行业中，张力控制器被广泛应用于对带状和线状类产品的张力进行控制，以确保生产过程中的稳定性和质量。

张力控制器可以直接设定要求控制的张力值，并通过输入张力传感器的信号（一般为毫伏级别）作为张力反馈值。控制器通过比较设定张力与实际张力值之间的偏差，将偏差值输入到PID（比例-积分-微分）控制器进行处理。然后，控制器输出相应的信号给外围执行机构（如磁粉离合器或磁粉制动器），以调整卷料的张力，使其达到设定的目标张力。

张力控制器具有以下特点：

1. 检测精度高：能够准确检测和控制张力的微小变化。
2. 稳定性好：通过PID控制算法，可以迅速调整张力值，保持系统的稳定性。
3. 适用范围广：适用于各种需要控制张力的工业生产线，如电线电缆、光纤光缆、塑料薄膜、纸张等。
4. 操作简便：通常具有液晶显示屏，可以显示当前张力值、设定张力值和其他相关参数，方便用户进行监控和调整。

此外，一些高 级的张力控制器还具有手动控制功能、卷径推算功能和锥度调节功能等，以满足不同应用场景的需求。

总之，张力控制器是一种重要的控制仪表，在工控行业中发挥着关键作用。它能够实现对带状和线状类产品张力的精 确控制，提高生产过程的稳定性和产品质量。

Tension controller is a kind of control instrument, usually developed by a single chip microcomputer or some embedded devices and peripheral circuits. In the industrial control industry, tension controllers are widely used to control the tension of ribbon and linear products to ensure stability and quality in the production process.

The tension controller can directly set the tension value required to be controlled, and use the signal of the input tension sensor (generally in the millivolt level) as the tension feedback value. The controller compares the deviation between the set tension and the actual tension value, and inputs the deviation value to the PID (proportional-integral-differential) controller for processing. The controller then outputs a corresponding signal to a peripheral actuator (such as a magnetic powder clutch or magnetic powder brake) to adjust the tension of the coil so that it reaches the set target tension.

The tension controller has the following features:

High detection accuracy: small changes in tension can be accurately detected and controlled.

Good stability: Through the PID control algorithm, the tension value can be quickly adjusted to maintain the stability of the system.
Wide range of application: suitable for all kinds of industrial production lines that need to control tension, such as wire and cable, optical fiber and cable, plastic film, paper, etc.

Easy to operate: it usually has a liquid crystal display screen, which can display the current tension value, set the tension value and other related parameters, which is convenient for users to monitor and adjust.

In addition, some advanced tension controllers also have manual control functions, roll diameter estimation functions and taper adjustment functions to meet the needs of different application scenarios.

In short, the tension controller is an important control instrument that plays a key role in the industrial control industry. It can realize the precise control of the tension of banded and linear products, improve the stability of the production process and product quality.
