為了控制張力，需要構(gòu)成張力控制系統(tǒng)，因?yàn)閺埩χ荒茉趦?或兩個(gè)以上)具有驅(qū)動(dòng)(或制動(dòng))力的工藝設(shè)備間形成，所以張力控制系統(tǒng)是在頂人傳動(dòng)控制系統(tǒng)其礎(chǔ)上構(gòu)成的，其中一個(gè)傳動(dòng)控制系統(tǒng)作為張力控制系統(tǒng)的速度其準(zhǔn)，稱為速度其準(zhǔn)系統(tǒng)、而另一個(gè)傳動(dòng)控制系統(tǒng)按張力要求建廣負(fù)載，形成張力，實(shí)質(zhì)是對(duì)速度基準(zhǔn)系統(tǒng)按要求張力進(jìn)行速度跟隨，稱為張力可控的速度跟隨系統(tǒng)，張力控制的任務(wù)一般多放在后一系統(tǒng)上，所以人們習(xí)慣地只將后者稱為張力控制系統(tǒng)。

張力控制系統(tǒng)由于應(yīng)用場(chǎng)合、設(shè)備、構(gòu)成原理不同而多種多樣。但按結(jié)構(gòu)形式、控制原理可大致將其歸納為直接張力控制系統(tǒng)、間接張力控制系統(tǒng)活套張力控制系統(tǒng)大類

Tension electronics covers a wide range of applications and comes in three versions with different levels of performance and functionality, all three versions have multilingual digital display and configuration keys for setting different parameters and checking the status of the tension system.
The 2 x 16 character display can display sum, difference, or individual load cell signals.
All three models are available in DIN rail and closed IP 65(NEMA4) models for installation in harsher environments
In order to control the tension, it is necessary to form a tension control system, because the tension can only be formed between two (or more) process equipment with driving (or braking) force, so the tension control system is formed on the basis of the top transmission control system, in which a transmission control system is used as the speed of the tension control system. It is called the speed of the quasi-system, and another transmission control system according to the tension requirements to build a wide load, forming tension, in essence, the speed of the speed reference system according to the required tension to follow, called the tension controllable speed following system, the task of tension control is generally placed on the latter system, so people are accustomed to only the latter is called the tension control system.
Tension control systems are varied due to different applications, equipment and composition principles. However, according to the structure and control principle, it can be roughly summarized into direct tension control system, indirect tension control system looper tension control system
The direct tension control system realizes the closed-loop feedback control of the tension through the tension detection link tension detection sensor. The direct tension control system between the coiler and the frame of the machine is shown in Figure 1 (a) and (b) respectively
Yes. To achieve direct tension control, first there is a tension detection sensor (tensiometer), which is installed under the tension roll of the tension measuring mechanism (see Figure 1). The tension gauge is actually a pressure gauge, and the current pressure gauge has various types such as pressure application 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
