Beschreibung
Zusammenfassung:	FIELD: physics.SUBSTANCE: this device comprises piezo-transducer with load the electrode of which are connected with current amplifier input while amplifier output is connected via cable measuring line with recorder. Piezo-transducer load is composed of ohmic voltage divider. Low-resistance arm of said divider is composed by wave impedance of extra measuring line cable connected with extra recorder. Note here that electric circuit parameters are selected proceeding from the following terms: R
