Ụkpụrụ na ọrụ nke ultrasonic nyocha

1. Gịnị bụ ultrasonic nyocha

Nyocha a na-eji nyocha ultrasonic bụ transducer nke na-eji mmetụta piezoelectric nke ihe na-eme ka ọ ghọta mgbanwe nke ike eletrik na ike ụda.Isi ihe dị na nyocha ahụ bụ wafer, nke bụ otu kristal ma ọ bụ polycrystalline nke nwere mmetụta piezoelectric.Ọrụ ahụ bụ ịtụgharị ike eletrik na ike ụda na ibe ya.
