Abstract

Prezenta inventie se refera la un accelerometru axial piezoelectric pentru detectarea si masurarea caracteristicilor vibratiilor. Accelerometrul, conform inventiei, în scopul evitarii frecarilor dintre piesele componente este alcatuit dintr-un pivot de sustinere pe care, prin intermediul unui strat de adeziv este lipita o pastila piezoelectrica pe care, de asemenea, printr-un strat de adeziv este lipita o masa seismica, a carei actiune pulsatorie inertiala asupra pastilei piezoelectrice-la miscarea oscilatorie a pivotului de sustinere, asamblat solidar cu piesa de proba-genereaza impulsurile piezoelectrice, ce se transmit printr-un cablu ecranat spre aparatul de prelucrare a semnalului, iar în scopul optimizarii sensibilitatii, masa seismica-care reprezinta elementul activ-poate fi marita prin adaugarea unor inele de adaos de forma si greutatea adecvata masuratorii de efectuat.The present invention refers to a piezoelectric axial accelerometer for detecting and measuring vibration characteristics. The accelerometer, according to the invention, in order to avoid friction between the component parts, is made up of a support pivot on which, by means of a layer of adhesive, a piezoelectric tablet is glued to which, also through a layer of adhesive, a table is glued seismic, whose inertial pulsating action on the piezoelectric pill - to the oscillating movement of the supporting pivot, assembled solidly with the test piece - generates the piezoelectric impulses, which are transmitted through a shielded cable to the signal processing device, and in order to optimize the sensitivity , the seismic mass - which represents the active element - can be increased by adding additional rings of the appropriate shape and weight for the measurements to be performed.
