Page 19: Principles Of Ultrasonic Measurement
RINCIPLES OF LTRASONIC EASUREMENT Time versus thickness relationship Ultrasonic thickness measurements depend on measuring the length of time it takes for sound to travel through the material being tested. The ratio of the thickness versus the ti is known as the sound velocity. In order to make accurate measurements, a sound veloci must be determined and entered into the instrument. - Page 20 The instructions must be used in the sequential order specified, as follow selected, the transducer is placed on a reference disk, located on top of the TI-CMXDL, and a key is pressed to establish a zero point for the particular transducer. If the Auto Zero feature is enabled, a simple key press will perform an electronic zero to establish the same zero point.

Page 22: Selecting The Measurement Mode
Which mode & transducer do I use for my application? High penetration plastics and castings The most common mode for these types of applications is pulse-echo. The TI-CMXDL has been optimized for cast materials. Cast iron applications require 1 - 5MHz frequencies, and cast aluminum requires a 10MHz frequency. - Page 23 This is a signal that appears at the surface of the material when using a dual elem The Differential Mode of the TI-CMXDL provides the user with the ability to set a nomi- delay line probe. Select a higher frequency transducer to reduce this noise – 7.5MHz an nal value, according to what the expected thickness should be, and measure the +/- differ- higher for better resolution.
