Abstract
Ujawniony jest czujnik drgań przeznaczony do bezinwazyjnego zamontowania na powierzchni badanego elementu (2). Czujnik drgań zawiera trwale osadzony na powierzchni badanego elementu (2) czujnik piezoelektryczny (1), który oddzielony jest od powierzchni badanego elementu (2) warstwą klejową (3). W warstwie klejowej (3) osadzony jest pręt stalowy (4), który przebiega centralnie wzdłuż płaszczyzny styku czujnika piezoelektrycznego (1) z powierzchnią badanego elementu (2), przy czym swoją górną powierzchnią styka się z dolną powierzchnią czujnika piezoelektrycznego (1), a swoją dolną powierzchnią styka się powierzchnią badanego elementu (2).
