Abstract

Traductorul piezoelectric destinat masuratorii acceleratiilor vibratiilor si deplasarilor, în scopul realizarii unui raport cît mai mare între masa seismica si masa totala si al simplificarii constructive, este alcatuit dintr-un corp pe care se sprijina niste discuri piezoelectrice si o masa seismica, prevazuta la partea sa inferioara cu un brîu circular, iar la partea superioara are o proeminenta, întregul ansamblu fiind închis cu un capac, care prezinta la partea sa superioara, trei zone de grosimi, dintre care primele doua asigura sprijinul si centrarea masei seismice, iar a treia zona asigura pretensionarea masei seismice.
