COMBINED MULTI-SECTIONAL ULTRASONIC IMMERSION PIEZOELECTRIC TRANSDUCER

摘要

Use: for fault detection and thickness measurement during the examination of different types of materials. Essence: the combined multi-sectional ultrasonic immersion piezoelectric transducer comprises piezoelements arranged in identically shaped pairs about the longitudinal axis of the transducer and situated at an acute angle to the acoustic axis of the piezoelectric transducer, and the acoustic axes of the piezoelements intersect on the longitudinal axis of the transducer in the direction of emission of the transducer, wherein the acoustic axes of all of the piezoelements are situated in the same plane, which passes through the longitudinal axis of the transducer, and the lens is common to all of the piezoelements or consists of individual sections which are connected at the junctions therebetween by a binding agent, for example an adhesive or a polymer compound. Technical result: an increase in the length of the working zone of the piezoelectric transducer and a broadening of the radiation pattern thereof.
