  • Page 41: Chapter Four Principals Of Ultrasonic Measurement

    CHAPTER FOUR PRINCIPALS OF ULTRASONIC MEASUREMENT 4.1 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 time is known as the sound velocity. In order to make accurate measurements, a sound velocity must be determined and entered into the instrument.

  • Page 42: Temperature

    Dakota NDT 4.5 Temperature Temperature has an effect on sound velocity. The higher the temperature, the slower sound travels in a material. High temperatures can also damage transducers and present a problem for various liquid couplants. Since the sound velocity varies with temperature it is important to calibrate at the same temperature as the material being measured.

Dual element transducers are normally used in pulse-echo mode for finding defects, and in echo-echo mode for through coating measurements.
  • Page 44 Dakota NDT jump has not occurred, providing an additional level of confidence to the measurement. The disadvantage is that 3 reflections are needed which requires the use of gates with controllable thresholds to adjust for sensitivity over a given measurement range.

By using echo-echo mode, the user is able to successfully measure through both, the coating and steel, and completely eliminate the thickness of the paint or coating.

    CHAPTER EIGHT THRU PAINT MEASUREMENT TECHNIQUE 8.1 Introduction to Thru Paint Measurement The principle behind thru paint measurement is by measuring the time between two backwall echoes returning from the test material. Since both of these backwall echoes travel the same path through the paint or coating, the thickness of the coating is subtracted out of the measurement so that only the actual material thickness can be measured.
