METHOD OF MEASURING AMPLITUDE OF VIBRATIONS Russian patent published in 2013 - IPC G01H9/00 G01H11/08 

FIELD: physics.

SUBSTANCE: piezoelectric detector with a point contact measures the amplitude of vibration and distribution thereof on radiating transition surfaces, compares said amplitude with the amplitude of vibration of the end surface while applying, across the piezoelectric transducer of the vibrating system, a voltage which does not exceed 0.1 times the operating voltage when exciting vibrations in air; the vibrating system is immersed in treated liquid such that the radiating end surface is not covered by the liquid; operating voltage is applied across the piezoelectric transducer of the system; amplitude of vibration of the end surface of the radiator is measured, while observing an enlarged image of light flux overlapped by the vibrating end surface and using the results of comparing amplitude of vibrations obtained by the piezoelectric detector with a point contact, the amplitude of vibration of the radiating transition surfaces and distribution thereof in the treated liquid are established.

EFFECT: enabling measurement of the amplitude of vibration of an ultrasonic transducer in process media during operation of a radiator.
