Ultrasonic sensors are predestined for monitoring the fill level of liquids, granules and bulk material.
During winding and unwinding operations, distance-measuring ultrasonic sensors precisely measure the outer diameter of rolls with materials such as plastic foil, sheet metal, paper and cardboard, veneer, etc.
The distance to objects can be measured reliably regardless of reflectance, transparency or color of the surface with ultrasonic sensors.
The distance measurement is based on a time-of-flight measurement. The sensor calculates the time between sending and receiving the reflected sound signal.
Advantage: Immunity to moisture, light, steam or object color
Ultrasonic sensors offer a high degree of flexibility in installation. Learn more about what you should consider when mounting ultrasonic sensors.
