Ultrasound refers to sound waves with a frequency above the upper limit of human hearing, which is approximately 20 kHz. The document discusses several industrial applications of ultrasound sensors, including winding and unwinding detection, slope control, height measurement, position control, collision protection, level sensing, and filling sensing in industries like automotive, packaging, printing, and more. It also outlines some biomedical uses of ultrasound like pelvic imaging and lithotripsy. Ultrasound is used for range finding in SONAR systems and ultrasonic cleaning of delicate parts.

2. Ultrasound is cyclic sound
pressure with a frequency greater
than the upper limit of human
hearing. Although this limit varies
from person to person, it is
approximately 20 kilohertz
(20,000 hertz) in healthy, young
adults and thus, 20 kHz serves as a
useful lower limit in describing
ultrasound.

6. Industrial Application

7. 1.Winding & Unwinding Ultrasound sensors are used to detect the changes in
diameter of drums and reels as they are wound or
unwound. Typical industries are:
•Paper and Printing
•Metal working
•Textiles
•Packaging
•Plastics
INDUSTRIAL APPLICATIONS

8. 2. Slope Control Ultrasonic sensors are used to monitor the
slope of loops of material in a process. They
are the sensing components of systems that
control continuous running of flexible
material. Typical industries are:
•Paper and Printing
•Chemicals
•Textiles
•Metal Working
•Packaging
INDUSTRIAL APPLICATIONS

9. 3. Height Measurement With high accuracy and repeatability,
ultrasonic sensors are used to measure the
height of objects that are moving past the
sensor. Measurements are generally
unaffected by surface finishes and shapes
of the measured objects. Industries where
this type of application are found include:
•Automotive
•Packaging and Distribution
•Printing
•Metal Working
•Assembly
•Agriculture
INDUSTRIAL APPLICATIONS

10. 4. Position Control Pairs of ultrasonic sensors are used to accurately
position objects. Linked together in a control
system. the sensors provide the prime input for
object location and position adjustment.
Industries using these applications include:
•Automotive
•Packaging
•Printing
•Assembly
•Robotics
•Plastics
INDUSTRIAL APPLICATIONS

11. 5. Collision Protection Ultrasonic sensors are attached to
moving objects and equipment to
provide collision protection. The sensor
continuously relays proximity data to a
controller. Many industrial users
include:
•Automotive
•Automation
•Logistics
•Metal Working
INDUSTRIAL APPLICATIONS

12. 6. Level Sensing Ultrasonic sensors have a unique
ability to detect uneven surfaces and
return accurate distance data. The
sensors are used in many applications
where the detection of the level of a
fluid in a container is needed. Typical
industries include:
•Food and Beverage
•Chemical
•Water Treatment
•Power Generation
INDUSTRIAL APPLICATIONS

13. 7. Filing Sensing Ultrasonic sensors can accurately
detect the changing levels of powders,
grains and other semi fluid
substances. Many industrial users
include:
•Agriculture
•Chemicals
•Packaging
•Fluid Handling
INDUSTRIAL APPLICATIONS

15. Biomedical ultrasonic applications
•According to Radiology Info, ultrasounds
are useful in the detection of pelvic
abnormalities and can involve techniques
known as abdominal (transabdominal)
ultrasound, vaginal (transvaginal or
endovaginal) ultrasound in women, and
also rectal (transrectal) ultrasound in men.
•Focused high-energy ultrasound pulses can
be used to break calculi such as kidney
stones and gallstones into fragments small
enough to be passed from the body without
undue difficulty, a process known as
lithotripsy.
