涵盖各种应用的张力控制器共有三种型号，每个型号的性能与功能水平各有不同。所有三种型号都配备多语言数字显示器和功能按键。功能按键被用于设置不同的参数并且检查张力测量系统的状态。2x16位数字 显示器可以显示和信号、差信号或各个压头的信号。所有三个型号分别都有两种安装方式，包括标准导轨式安装和适用于更恶劣环境中的封闭式安装IP65。

PFEA112-20张力控制器是一种用于收放卷保持恒张力的控制设备，搭配磁粉制动器/离合器，可以调节扭力输出，从而达到张力稳定。其主要分为手动张力控制器、演算型张力控制器、全自动张力控制器：

- 手动张力控制器：对于精度要求不高，且操作人员参与度高的收放卷应用场景，可以选用手动张力控制器。该控制器还可以外接PLC，实现半自动功能。

- 演算型张力控制器：属于半自动的张力控制器，能通过多种检测方式测量卷料半径并自动进行张力演算，进行开环张力控制。

- 全自动张力控制器：是一种高精度、多功能的全数字智能型张力控制器，配合张力检测器组成闭环张力控制系统。通过接收张力传感器传送的信号，经内部PID运算处理后，调节执行机构，自动控制材料的收放卷张力，从而达到实时监测、实时调节的作用。

PFEA112-20张力控制器在印刷、包装、塑料、造纸、线缆等行业中都有广泛的应用。如需了解更多张力控制器的信息，可以继续向我提问。

overview

There are three models of tension controllers for a variety of applications, each with a different level of performance and functionality. All three models are equipped with multilingual digital displays and function keys. Function keys are used to set different parameters and check the status of the tension measuring system. The 2x16-bit digital display can display sum signals, difference signals, or signals from individual indenters. All three models are available in two mounting options, including standard rail mounting and enclosed mounting IP65 for harsher environments.

The PFEA112-20 tension controller is a control device used to maintain constant tension with a magnetic powder brake/clutch that adjusts the torque output to achieve tension stability. It is mainly divided into manual tension controller, calculus tension controller, automatic tension controller:

- Manual tension controller: Manual tension controller can be used for winding application scenarios with low precision and high operator involvement. The controller can also be connected with an external PLC to achieve semi-automatic function.

- Calculus tension controller: It is a semi-automatic tension controller, which can measure the radius of the coil through a variety of detection methods and automatically perform tension calculation for open loop tension control.

- Automatic tension controller: is a high-precision, multi-functional digital intelligent tension controller, with tension detector to form a closed-loop tension control system. By receiving the signal transmitted by the tension sensor, after the internal PID operation processing, the actuator is adjusted to automatically control the tension of the material, so as to achieve real-time monitoring and real-time adjustment.

PFEA112-20 tension controller has a wide range of applications in printing, packaging, plastics, paper, cable and other industries. To learn more about tension controllers, keep asking me questions.
