摘要
Barkhausen emission is well known phenomena used in non-destructive testing techniques of ferromagnetic materials. Weaknesses of the methods based on Barkhausen emission are related to difficulties of ensuring measurement reproducibility because of specimen influence upon measurement channel. In this paper we propose method of sensor calibration prior to measurement. To implement sensor calibration its design modifications and data processing procedures were suggested.
