Ultrasonic Interferometer - Amrita Vishwa Vidyapeetham Virtual Lab
Ultrasonic interferometer is a simple device which yields accurate and consistent data, from which one can determine the velocity of ultrasonic sound in a liquid medium. Ultrasonic sound refers to sound pressure with a frequency greater than the human audible range (20Hz to 20 KHz).
Ultrasonic Testing (UT) Calculations - NDT Inspect
2023年2月11日 · Ultrasonic testing (UT) is a non-destructive testing method that uses high frequency sound waves to inspect materials for defects. The following are some of the key calculations used in ultrasonic testing: The wavelength of an ultrasonic wave is calculated using the formula: Wavelength (λ) = Velocity of sound (c) / Frequency (f)
Nondestructive Evaluation Techniques : Ultrasound
Measurements of sound velocity and ultrasonic wave attenuation can be related to the elastic properties that can be used to characterize the texture of polycrystalline metals. These measurements enable industry to replace destructive microscopic inspections with …

A new instrument for precise measurements of velocity of sound in gases was developed and tested. The instrument implements improved velocity of sound measuring technique based on time-of-flight measurement of ultrasonic pulses. The instrument was …
Two methods were used for the ultrasound velocity measurements in liquid media: interferometric and pulse-echo. The interferometric method is traditional and more suitable for precise absolute measurements over a frequency range, while the pulse -echo is convenient for the determination of ultrasound velocity variations in small volumes.
Ultrasonic Velocity Measurement - an overview - ScienceDirect
Ultrasonic velocity changes can be determined by time-of-flight measurements using the conventional pulse–echo methods, or using cross-correlation methods for precise measurements. A typical accuracy of ±0.1% in ultrasonic velocity measurements is essential for the characterization of microstructures.
