How Can I Build a Simple Ultrasonic Thickness Gauge?

Click For Summary
SUMMARY

The discussion centers on building a simple ultrasonic thickness gauge for a final project. The user has struggled to find relevant electronic circuit designs and tutorial videos, primarily encountering information on industrial digital ultrasonic thickness gauges. A suggestion was made to study quartz crystal microbalances (QCM) and the Saurbrey equation, which are essential for understanding film thickness measurement techniques.

PREREQUISITES
  • Basic understanding of ultrasonic technology
  • Familiarity with electronic circuit design
  • Knowledge of quartz crystal microbalances (QCM)
  • Understanding of the Saurbrey equation
NEXT STEPS
  • Research ultrasonic transducer selection for thickness measurement
  • Learn about the Saurbrey equation and its applications in QCM
  • Explore circuit design software for prototyping electronic circuits
  • Investigate existing ultrasonic thickness gauge projects on platforms like GitHub
USEFUL FOR

Students in engineering fields, hobbyists interested in electronics, and anyone looking to build or understand ultrasonic measurement devices.

Homework Statement


I want to built a simple ultrasonic thickness gauge for my final project. I have already search in google about that simple electronic circuit but i can't found it and also i have already looking for tutorial video in youtube about how to built simple ultrasonic thickness gauge but the result about digital ultasonic thickness gauge in factory . Please, any suggestion ? (sorry, if any mistake in my words)

Homework Equations


for now, i don't have relevant equations

The Attempt at a Solution


I have already search the solution in google and youtube but i can't found the detailed solution (sorry, if any mistake in my words)

You might find it helpful to study the theory behind quartz crystal microbalances (QCM), which are widely used in thin films to determine film thickness. They are based on the Saurbrey equation, which you can find more about on Wikipedia. Hope that helps...
 
thank you for your suggestion :), i will study the theory behind quartz crystal microbalances (QCM),
