Ultrasonic Measurement of Air Gap Between Metal Walls Using Bending Waves

By Alex Karpelson and Kinectrics Inc

Abstract

Design, containing two metal walls (e.g. tubes, plates, or other parts) with air/gas gap between them, is typical in many industries. Because of various reasons (aging, size change, temperature and radiation influence, vibrations, creep, mechanical displacements and others) this air gap changes during product lifetime. Such a change can lead to system malfunction and even damage
