This process often takes place in specific control zones: unwind/payout, process (nip), and rewind/take up, with each having unique tension control requirements. The DGT300+ is a digital tension controller dedicated to web tension and torque control. The LCD and indicators make the user can opearate the controller easily without long time learning. This means that as a roll diameter increases or decreases, torque must be adjusted to maintain tension at the optimal value, or setpoint. The entire range is tested completely before final delivery. Overall, installing a web tension controller can decrease the variation of tension significantly. Open loop systems are generally less expensive than closed loop systems because you are not utilizing additional products, like load cells. In your current application could you double your speed without sacrificing end product quality? Our tension controllers are widely demanded in the market for various weighing and measurement purposes. This paper is a review of the fundamentals of web tension control, covering the following topics; Machine sections (unwinds, rewinds and driven m… Customers can avail a wide range of Tension Controller from us. The measuring force is detected via a bi-directional strip to which the strain gauges are applied, as a result of which an analogue measured signal proportional to the web tension is output. Tension is the pull or strain put on a web of material that tends to stretch it in the machine direction. Buying Web Tension Controllers. Automating the process, creating a continuous process and increasing productivity are all going to rely heavily on proper tension control to ensure consistent and high-quality results. Web tension and control sensors are the input devices used with tension control systems and web guide systems. Web Tension Controllers by Double E. Double E offers a variety of web tension control systems available using load cells, dancers, ultrasonic sensors, and amplifiers. The latest of the tension controls’ family of IBD Wickeltechnik is web@tens, which adds new characteristics such as the compact dimensions and the easiness to use, to the basic functions that have allowed our MW.90.10 to be distributed worldwide. ABB’s web tension system is the perfect choice for measuring web tension in paper mills or converting applications such as printing, laminating, coating, slipping, sheeting etc. It integrates two separate Digital PID Controllers and two separate Open Loop controls. Web Tension Measurement devices include load cells or a dancer position feedback sensor, that are constantly relaying tension changes directly from the web of material to the tension controller, which regulates the output of the torque device, which may be a … As mentioned, one of the key elements to improved productivity and profitability can be traced to the lack of effective tension control. On the sensor rollers used for web tension control, two load cells are already integrated in the roller body. Web Tension Control - Closed or Open Loop Configurations The Double E Tension controller is a DIN rail mountable controller that is configurable for multiple uses. Our tension controllers are reasonably priced. It is intended for operators, designers and engineers who would like a better Quality tension control helps to eliminate these scrap producers by creating a uniform and consistent process. Because tension control is the outmost control loop, the response time is slow compared to that of torque control or speed control. Other sources of scrap and lost productivity come from web breaks, and inconsistent end product. The core of T-one is the P.I.D. Tension control and regulation are necessary to keep constant the desired web tension, avoiding the possibility of material breaks in any phase of web … There are three types of tension control: Just as it implies manual control is the process of visually or physically determining if tension is correct, and then making manual adjustments to maintain the desired tension level.
