Abstract

FIELD: ultrasound devices. SUBSTANCE: transducer is protected against severe chemical conditions by fluoroplastic or polyethylene housing. New method of gluing piezoelectric member to housing bottom, which serves for acoustic matching results in conversion of radial and transversal oscillations of piezoelectric member to output signal of acoustic transducer. Device may be used in acoustic level gages, echo sounders, alarm and other devices which operations are based sounding liquid or gas by ultrasound. EFFECT: increased efficiency of operations at resonant frequencies corresponding to different modes of oscillations of cylindrical piezoelectric member.

Изобретение относится к области ультразвуковой техники и может быть использовано в акустических уравномерах сред, эхолотах, сигнализаторах, в других устройствах, работа которых основана на зондировании ультразвуком в жидкой или газовой средах. Целью изобретения является повышение эффективности работы химически стойкого акустического преобразователя, заключенного во фторопластовый или полиэтиленовый корпус, на резонансах, соответствующих различным модам колебаний цилиндрического пьезоэлемента, входящего в состав преобразователя, за счет применения способа склейки пьезоэлемента с дном корпуса, играющим роль акустического согласования. Использование склейки позволяет преобразовывать радиальные и толщинные колебания пьезоэлемента в эффективный сигнал акустичестического преобразователя.The invention relates to the field of ultrasonic technology and can be used in acoustic equalization of media, echo sounders, alarms, in other devices, the operation of which is based on sounding by ultrasound in liquid or gas environments. The aim of the invention is to increase the efficiency of a chemically stable acoustic transducer enclosed in a fluoroplastic or polyethylene housing, at resonances corresponding to various vibration modes of a cylindrical piezoelectric element included in the transducer, through the application of a method of gluing a piezoelectric element with the bottom of the body playing the role of acoustic matching. Using gluing allows you to convert the radial and thickness vibrations of the piezoelectric element into an effective signal of the acoustic transducer.
