Based on the conducted experimental studies, the necessary parameters were selected to provide reliable testing of concrete defects. The measuring system must have: input sensitivity of the receiving electromagnetic channel of at least100 µV, the working frequency range of 1-120 kHz; the sampling frequency of 500 kHz, as well as a device that allows fast Fourier transform. The registration of the electrical response during an elastic impact should be made by a differential electric sensor, which allows measurements under conditions of external electromagnetic interference.
