It can also output 0-10V voltage signal to control vfd, servo motor or other actuators to perform high-precision tension control on the coil material. Web Tension Controllers Web tension has an important role in the sectors of converting, paper and carton board, aluminium foil, textile, wire and cables. • It is impossible to control your web without proper tension being applied to it. Operators simply input the parameters of the production run (such as speed, tension, etc), press start/run and allow the controller to automatically manage production. If any changes in tension are detected the controller can instantly alter the torque device to maintain set tension. The features like strain gauge based sensors, easy tension calibration and automatic as well as manual tension control make these products a preferred choice of many clients. Proper tension must be maintained to prevent stretching, wrinkling, breaking, or inconsistent print registration of the material during its process. Accurate and stable tension control ensures the highest product quality and productivity. Load Cells measures Tension ! 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. Accurate web tension measurement is a prerequisite for keeping the web tension constant within the desired range, during both acceleration and deceleration. 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. Load Cell Amplifiers The sensor provides a high precision signal with high speed and can be applied in conjunction with magnetic powder brakes, pneumatic brakes, electric motors, etc. Controller compares actual tension to desired tension !
