How Can We Measure Vibration Amplitude with an Eddy Current Displacement Sensor?

AI Thread Summary
Eddy current displacement sensors can measure vibration amplitude by detecting changes in the distance between the sensor and the vibrating sheet. The sensor operates by generating an electromagnetic field, which interacts with the conductive material of the sheet, producing eddy currents. The amplitude of vibration can be inferred by analyzing the variations in the sensor's output signal as the sheet vibrates. The coursework focuses on how the time for the amplitude to halve is affected by the magnetic flux density in which the sheet is placed. Understanding the sensor's working principle is crucial for accurate measurements in this context.

how can we measure the amplitude of vibration of a sheet with and eddy current displacement sensor?:confused: :frown: :cry:



my course work is :
how the time taken for the amplitude of vibrating sheet of aluminium to halve,varies with the magnetic flux density of the field in which the sheet is placed.
I wanted to know how does an eddy current displacement sensor or vibration sensor works?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
