US.3 is an ultrasonic sensor for detecting the diameter of the roll; it is usually used for the web tension control in open-loop systems combined with a pneumatic brake, a clutch (on rewinding stations) or a motor. It can also be used in combined or closed-loop systems as a support to the tension controllers. US.3 is equipped with an easy interface with a led bar and two buttons. Easy to use and install, economic and accurate, US.3 is the ideal solution for use on sheeters, slitter rewinders and bag making machines.
