A roll diameter tension controller can be set, and only a proximity switch or an encoder needs to be installed to measure the roll radius, and the controller performs tension control according to the roll diameter.

SC-2H automatic tension controller adopts liquid crystal display, can choose Chinese and English display, the interface is friendly and easy to use, it can output 0-24V / 4A to directly drive magnetic powder clutch and magnetic powder brake; it can also output 0-5V and 0-10V , Control the inverter, servo motor or other actuators to perform high-precision tension control on the winding system. It can be widely used in papermaking, printing, packaging, textile, printing and dyeing industries. SC-2H type automatic tension controller can be equipped with roll diameter tension controller, only need to install a proximity switch or encoder to measure the roll radius, the controller will control the tension according to the roll diameter.
