One of the techniques of the Ultrasonic method which can be utilized for other purposes than to find internal discontinuities is the Thickness Measurement technique.
Checking for corrosion, wall thinning, delaminates on composite structures and general thickness readings can be done using our simple to use portable equipment. Any type of solid material can be tested in this way. The only important factor that needs to be taken into consideration is that sound travels differently in different materials. Multiple readings can be obtained and stored for later download and reporting. Thickness readings from less than 1.0 mm with much greater distances are possible to obtain using our equipment. Another important factor playing a role with thickness measurements is that the surface needs to be adequately prepared as other than the normal materials will interfere with the readings obtained.
