Fasahar matsa lamba huɗu na firikwensin matsa lamba

1. Capacitive

Capacitive matsa lamba na firikwensin yawanci ana fifita su da babban adadin aikace-aikacen ƙwararrun OEM. Gano canje-canjen ƙarfin aiki tsakanin saman biyu yana ba wa waɗannan na'urori damar jin ƙarancin matsa lamba da matakan vacuum. A cikin tsarin firikwensin mu na yau da kullun, ƙaƙƙarfan matsuguni ya ƙunshi filayen ƙarfe biyu masu nisa kusa da juna, a layi daya da keɓancewar lantarki, ɗaya daga cikinsu ainihin diaphragm ne wanda zai iya lanƙwasa kaɗan ƙarƙashin matsin lamba. Waɗannan fitattun filaye (ko faranti) an ɗora su ta yadda lanƙwasa taron ya canza ratar da ke tsakaninsu (a zahiri suna samar da capacitor mai canzawa). Ana gano canjin da aka samu ta hanyar da'irar kwatancen layi mai mahimmanci tare da (ko ASIC), wanda ke haɓakawa da fitar da sigina mai ma'ana.

2.CVD irin

Hanyar tururin sinadarai (ko "CVD") hanyar masana'anta tana haɗe murfin polysilicon zuwa diaphragm na bakin karfe a matakin kwayoyin, don haka samar da firikwensin tare da kyakkyawan aikin ɗigo na dogon lokaci. Ana amfani da hanyoyin masana'antu na yau da kullun na sarrafa semiconductor don ƙirƙirar gadojin ma'aunin ma'aunin polysilicon tare da kyakkyawan aiki a farashi mai ma'ana. Tsarin CVD yana da kyakkyawan aikin farashi kuma shine mafi mashahuri firikwensin a aikace-aikacen OEM.

3. Nau'in fim ɗin sputtering

Zubar da fim (ko "fim") na iya ƙirƙirar firikwensin tare da matsakaicin haɗin haɗin kai, hysteresis da maimaitawa. Daidaiton yana iya zama sama da 0.08% na cikakken sikelin, yayin da ɗigon dogon lokaci ya yi ƙasa da 0.06% na cikakken sikelin kowace shekara. Ayyukan kayan aiki na ban mamaki - firikwensin fim ɗin mu da aka watsar da shi wata taska ce a masana'antar gano matsi.

4. Nau'in MMS

Waɗannan na'urori masu auna firikwensin suna amfani da micro-machined silicon (MMS) diaphragm don gano canjin matsa lamba. An keɓe diaphragm na siliki daga matsakaici ta hanyar mai cike da 316SS, kuma suna amsawa a jere tare da matsa lamba na ruwa. firikwensin MMS yana ɗaukar fasahar masana'anta na gama gari, wanda zai iya samun juriya mai ƙarfi, madaidaiciyar layi, kyakkyawan aikin girgiza zafin zafi da kwanciyar hankali a cikin ƙaramin fakitin firikwensin.
