Ultrasonic proximity sensor
3.9" - 39.3", 0 - 10 V | U-B Series
Placid Industries
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 power supply. 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.
