Ultrasonic echography (A-Scan)

 Product No: P5160200

Principle

An ultrasonic wave transmitted in a sample will be reflected at discontinuities (defects, cracks). From the relationship between the time of flight of the reflected wave and the sound velocity, the distance between ultrasonic transducer and defects(reflector) can be calculated. Position and size of these defects can be determined by measuring in different directions.

Tasks

  1. Measure the longest side of the block with the calliper and the time of light of ultrasound wave for this distance with the 2 MHz probe
  2. Calculate the sound velocity.
  3. Measure the position and the size of the different defects of the test block with the calliper and the ultrasound echography method.
