Description
Wynalazek dotyczy uchwytu przetwornika piezo¬ elektrycznego zwlaszcza do aparatury ultradzwie¬ kowej.W dotychczas znanych urzadzeniach tego rodzaju, w celu zabezpieczenia przetwornika przed sciera¬ niem sie na powierzchniach metalowych, stosuje sie nakrecane denko ochronne, co posiada te nie¬ dogodnosc, ze energia ultradzwiekowa jest dodat¬ kowo prz_ez to denko tlumiona i odbijana przed wprowadzeniem do badanego materialu.Niedogodnosc te usuwa niniejszy wynalazek, po¬ legajacy na zastosowaniu w uchwycie przetworni¬ ka piezoelektrycznego zamiast wspomnianego den¬ ka ochronnego — pierscienia, umieszczonego tak, ze promieniujaca powierzchnia jest odslonieta.Wynalazek jest blizej wyjasniony przy pomo¬ cy rysunku, przedstawiajacego pionowy przekrój uchwytu przetwornika piezoelektrycznego.Na uchwyt 2 przetwornika 3 jest nakreeony za¬ miast denka pierscien i, wskutek czego powierzch¬ nia promieniujaca tego przetwornika piezoelektry- nego 3 jest calkowicie odslonieta, lecz nie moze sie zetknac z powierzchnia badanego materialu, *) Wlasciciel patentu oswiadczyl, ze twórca wy¬ nalazku jest inz. mgr Jerzy Wehr. lub przedmiotu 4, gdyz miedzy tym przedmiotem 4, a przetwornikiem 3 znajduje sie cienka warstia oliwy 5. Odleglosc miedzy badanym przedmiotem 4, a przetwornikiem 3 jest regulowana za pomoca wspomnianego pierscienia ochronnego 1. PLThe invention relates to a piezoelectric transducer holder, in particular for ultrasonic devices. Hitherto known devices of this type use a screw-on protective bottom to protect the transducer from abrasion on metal surfaces, which also has the disadvantage of ultrasonic energy. This inconvenience is removed by the present invention, which consists in using a piezoelectric transducer in the holder instead of the aforementioned protective cap - a ring, positioned so that the radiating surface is exposed. The invention is explained in more detail with the aid of a drawing showing a vertical cross-section of the piezoelectric transducer holder. The transducer holder 2 is drawn on the transducer holder 2 instead of the ring bottom, and as a result the radiating surface of this piezoelectric transducer 3 is completely exposed, but not may contact the surface of the tested material, *) The owner of the patent stated that the inventor was Eng. Jerzy Wehr. or object 4, because between this object 4 and transducer 3 there is a thin film of oil 5. The distance between the tested object 4 and transducer 3 is regulated by means of the said protection ring 1. EN
