Ultrasonic Sensor U-B MAINTAIN CONSTANT TENSION - The ultrasonic sensor is used for maintaining constant tension when using a brake for producing unwind (payout) tension, or when using a clutch for rewind tension. |
The sensor measures the diameter of the roll & sends a 0-10 VDC signal to the Placid Torque is automatically varied as roll size changes, to keep tension constant. Tension is adjusted by a remotely
mounted potentiometer. The sensor measures distances by sending an ultrasonic pulse of sound, and then measuring the time for the return echo pulse.
