通过张力检测环节 （张力检测传感器）实现对张力的闭环反馈控制的系统。卷取机和轧机机架间的直接张力控制系统分别如图1 （a）、（b） 所示。
实现直接张力控制，首先要有张力检测传感器（张力计）。它被装在张力测量机构的张力辊下（见图1）。张力计实为压力计，现用的压力计有压磁式、感应式、电阻应变片式等多种型式。
直接张力控制大多用于张力调节范围大， 精度要求高及易于安装张力计的场合， 或在无法构成间接张力控制系统时使用。
有时为了提高张力调节动态及静态性能， 扩大张力调节范围，用间接张力控制实现粗调，起扰动补偿作用，用直接张力控制实现精调，两者合在一起构成张力复合控制。
直接张力控制和张力复合控制多应用于带材、箔材冷轧机或连续加工线的卷取机或其机架间、加工设备间的张力控制上。

The system realizes the closed-loop feedback control of tension through the tension detection link (tension detection sensor). The direct tension control system between coiler and mill stands is shown in Figure 1 (a) and (b) respectively.
To achieve direct tension control, you must first have a tension detection sensor (tensiometer). It is mounted under the tension roll of the tension measuring mechanism (see Figure 1). The tensiometer is actually a pressure gauge, and there are many types of pressure gauges in use, such as piezomagnetic type, induction type, resistance strain gauge type, etc.
Direct tension control is mostly used in situations where the tension adjustment range is large, the accuracy is high and the tensiometer is easy to install, or when an indirect tension control system cannot be formed.
Sometimes, in order to improve the dynamic and static performance of tension regulation and expand the range of tension regulation, indirect tension control is used to achieve rough adjustment, play the role of disturbance compensation, and direct tension control is used to achieve fine adjustment.
Direct tension control and tension compound control are mainly applied to the tension control of strip and foil cold rolling machine or coiler of continuous processing line or between its frame and processing equipment.
