The possibility of pressure measuring with the help of piezoelectric waveguide sensors (PWGS) in the near zone of underwater spark discharge (USD) and corona discharge (CD) in water electrolites with high values of the electrical conductivity was studied. The sensors used were distingwished by their dimen- sions and the waveguide material as well as by their screenning. Comparison of the pressure oscillograms obtained with the use of the PWGD and the microsensor operating on the principle of volume action (Synany sensors) was conducted. Experimental data on the pressure distribution in water obtained with the use of the PWGS for USD and CD including the plasma region are presented.
