Tension controllers

US.3

Available

Diametral sensor.

US.3 is an ultrasonic sensor specifically designed to control the web tension in open-loop systems, but it is widely used to support also closed-loop tension control.
US.3 gives an analogue signal proportional to diameter/distance, which directly controls the brake or clutch, and so regulates the web tension depending on the remote setpoint.

The sensor is equipped with an easy structured interface with a led bar and two keys, in order to simplify the calibration and make its operation user friendly. Moreover US.3 can be programmed and calibrated by pc.
