Dangantaka tsakanin firikwensin matsa lamba piezoresistive da abubuwan fitarwa

Piezoresistive matsa lamba na'urori masu auna sigina nau'i ne na firikwensin matsa lamba wanda ke amfani da tasirin piezoresistive don auna matsa lamba.Tasirin piezoresistive yana nufin canjin juriya na lantarki na abu lokacin da aka yi masa rauni na inji ko nakasa.A cikin firikwensin matsa lamba na piezoresistive, ana amfani da diaphragm ko membrane yawanci don canza matsa lamba zuwa nakasar injina, wanda hakan ke haifar da canje-canje a juriyar abubuwan piezoresistive.

Dangantakar da ke tsakanin matsa lamba da fitarwa don firikwensin matsin lamba na piezoresistive yana rinjayar ƙira da kayan kayan firikwensin.Ga bayyani na gaba ɗaya dangantakar:

1.Direct Proportation Dangantaka:

A yawancin firikwensin matsa lamba na piezoresistive, akwai dangantaka ta kai tsaye da ta layi tsakanin matsa lamba da aka yi amfani da ita da kuma canjin juriya na lantarki.Yayin da matsin lamba ya karu, diaphragm ko membrane na firikwensin yana fuskantar nakasu, yana haifar da abubuwan da ke haifar da rauni.Wannan nau'in yana haifar da canji a cikin juriya, kuma wannan canji ya dace da matsa lamba.Ana iya auna canjin juriya ta amfani da da'irar gadar Wheatstone ko wasu hanyoyin daidaita sigina.

2.Wheatstone Gadar Kanfigareshan:

Piezoresistive matsa lamba na firikwensin sau da yawa suna amfani da da'irar gadar Wheatstone don auna canjin juriya daidai.Wurin da'irar gada ta ƙunshi abubuwa da yawa na piezoresistive, wasu daga cikinsu suna fuskantar matsin lamba, yayin da wasu kuma ba.Ana amfani da canjin bambancin juriya tsakanin abubuwan da ba su da ƙarfi da rashin ƙarfi don samar da ƙarfin fitarwa wanda ya dace da matsa lamba.

3. Fitar da Siginar Sharadi:

Fitowar firikwensin matsa lamba piezoresistive yawanci siginar ƙarfin lantarki ne na analog.Fitar da wutar lantarki yayi daidai da canjin juriya kuma, saboda haka, matsa lamba da aka yi.Za a iya amfani da da'irar sanyaya siginar don haɓakawa, tacewa, da daidaita siginar fitarwa don samun ingantaccen karatun matsi.

4.Kwanta:

Saboda ƙera haƙuri da bambance-bambance a cikin kaddarorin firikwensin, firikwensin matsa lamba na piezoresistive galibi suna buƙatar daidaitawa don tabbatar da ingantattun ma'aunin matsi.Daidaitawa ya ƙunshi tantance ainihin alakar da ke tsakanin ƙarfin fitarwa na firikwensin da ainihin matsi da ake amfani da su.Ana iya samun wannan daidaitawar ta hanyar gwaji da kwatanta daidai da ma'aunin tunani.

A taƙaice, alaƙar da ke tsakanin matsa lamba da fitarwa don firikwensin matsa lamba na piezoresistive yawanci layi ne da daidaitacce.Yayin da matsin lamba ya karu, juriya na firikwensin yana canzawa, yana haifar da canji mai dacewa a cikin ƙarfin fitarwa.Tsarin gadar Wheatstone da sanyaya sigina suna taka muhimmiyar rawa wajen canza canjin juriya zuwa ma'aunin matsi mai amfani kuma daidai.
