Knowledge of the tension controller

In the industrial sector in some band and linear type of products often need to control the tension to achieve the production requirements the tension controller is to control the tension of such an instrument the tension controller is embedded by a microcontroller or some developed with external circuit devices and systems is a control instrument it can directly control the tension set requirements and then directly enter the tension sensor signal (usually mV level) as the feedback tension values ​​obtained by comparison bias the input to the PID controller such as processing the best output to the external actuator to control and ultimately achieve the minimum deviation the purpose of the fastest system response. There are also manual tension controller control generally refers to people by a certain tension controller output given to the implementing agencies (often the amount of current to the motor); some of the tension controller also comes with volume projected path function general application in the winding device there is unwinding and winding the other; regulatory function in addition to the taper you can set the controller directly on the requirements of a number of technology take-up taper.
