The operating principle of pulse-echo method of control

In the method of controlling the amplitude of the echo of the echo signal characterizes the size of the reflector, and the time interval between the excitation probe pulse and the arrival of the echo pulse (travel time) corresponds to the location of the reflector. Note that the control method of pulse-echo amplitude of defectoscope (Descrydefect) echo signal depends in a complicated way:

• radiated energy;
• the characteristics of the source and the receiver;
• the size of the reflector;
• the position of the reflector;
• properties of the reflector;
• attenuation of the acoustic wave.
