Información básica

    Modelo: Soft PZT

DDescripción

PZT suave

Las cerámicas de alta sensibilidad o "blandas" presentan alta sensibilidad y permitividad, pero en condiciones de alta conducción son susceptibles de autocalentamiento más allá de su rango de temperatura de funcionamiento. Estos materiales se utilizan en varias pastillas y sensores, transductores de tipo motor de baja potencia, receptores y generadores de baja potencia.



La aplicación ideal de materiales piezo blandos es detectar las necesidades.


Los materiales de pizeo suave de Yuhai son PZT-5, PZT-5H, PZT-5X, PSnN-5 y PLiS-51.
