Ngwa ahụike ụlọ ọgwụ Toshiba PVT-712BT 11MC4 Micro Convex Ultrasound Probe

Nyocha Toshiba ndị ọzọ anyị nwere ike ịnye:

Isi ihe ọmụma

Ndị ntụgharị

Ndị transducers Ultrasonic na-atụgharị AC n'ime ultrasound, yana azụ. Ultrasonics, na-ezokarị aka na transducers piezoelectric ma ọ bụ transducers capacitive. Kristal piezoelectric na-agbanwe nha na ọdịdị mgbe a na-etinye voltaji; Voltaji AC na-eme ka ha na-emegharị n'otu oge ma na-emepụta ụda ultrasonic. Ndị ntụgharị ike na-eji oghere electrostatic n'etiti diaphragm na-eduzi na efere nkwado.

Enwere ike ikpebi ụkpụrụ nke transducer site na mpaghara transducer na-arụ ọrụ na ọdịdị ya, ogologo ikuku ultrasound, na ụda ụda nke mgbasa ozi mgbasa ozi. Eserese ndị a na-egosi mpaghara ụda nke ihe ntụgharị ultrasonic na-elekwasị anya na mmiri, n'ụzọ doro anya na ọkwa ike dị iche iche.

Ebe ọ bụ na ihe piezoelectric na-emepụta voltaji mgbe a na-etinye ike n'ahụ ha, ha nwekwara ike ịrụ ọrụ dị ka ihe nchọpụta ultrasonic. Ụfọdụ sistemu na-eji nnyefe na nnata dị iche iche, ebe ndị ọzọ na-ejikọta ọrụ abụọ ahụ n'ime otu transceiver piezoelectric.

Ultrasound transmitters nwekwara ike iji ụkpụrụ na-abụghị piezoelectric. dị ka magnetostriction. Akụrụngwa nwere akụrụngwa a na-agbanwe nha ntakịrị mgbe ekpughere ya na oghere magnetik, ma na-eme transducers bara uru.

Igwe okwu capacitor ("condenser") nwere diaphragm dị mkpa nke na-anabata ebili mmiri ultrasound. Mgbanwe na mpaghara ọkụ eletrik n'etiti diaphragm na efere nkwado dị nso na-agbanwe akara ụda ka ọ bụrụ ọkụ eletrik, nke enwere ike ịbawanye elu.

A na-ejikwa ụkpụrụ diaphragm (ma ọ bụ akpụkpọ ahụ) na ndị transducers ultrasonic micro-machined (MUTs) ọhụrụ dị ọhụrụ.

A na-emepụta ngwaọrụ ndị a site na iji teknụzụ micro-machining silicon (teknụzụ MEMS), bụ nke bara uru karịsịa maka imepụta arrays transducer. Enwere ike tụọ ma ọ bụ mee ka mkpọtụ nke diaphragm dị na eletrọnịkị site na iji ikike dị n'etiti diaphragm na efere nkwado dị nso (CMUT), ma ọ bụ site n'ịgbakwunye obere ihe piezo-electric na diaphragm (PMUT). N'aka nke ọzọ, nchọpụta na nso nso a gosiri na enwere ike tụọ ịma jijiji nke diaphragm site na obere mgbanaka mgbanaka anya agbakwunyere n'ime diaphragm (OMUS).

A na-ejikwa transducers Ultrasonic na levitation ụda olu.
