Matsa lamba firikwensin shine firikwensin firikwensin da aka fi amfani dashi a cikin ayyukan masana'antu, wanda aka yi amfani da shi sosai a cikin mahalli daban-daban na masana'antu ta atomatik, gami da kiyaye ruwa da wutar lantarki, sufurin jirgin ƙasa, gine-gine masu hankali, samar da sarrafa atomatik, sararin samaniya, masana'antar soja, petrochemical, rijiyoyin mai, lantarki wutar lantarki, jiragen ruwa, kayan aikin injina, bututun mai da sauran masana'antu da yawa. Kuma a wurare daban-daban, ana buƙatar amfani da nau'ikan firikwensin matsa lamba don guje wa kurakurai.

Ka'idodin aiki na na'urori masu auna matsa lamba daban-daban

1. Piezoresistive Force firikwensin: Ma'aunin ƙarfin juriya yana ɗaya daga cikin manyan abubuwan da ke tattare da firikwensin damuwa. Ka'idar aiki na ma'aunin juriya na ƙarfe shine al'amari cewa juriya da aka tallata akan kayan tushe yana canzawa tare da nakasar injina, wanda akafi sani da tasirin juriya.

2. Na'urar firikwensin yumbu: firikwensin yumbura yana dogara ne akan tasirin piezoresistive, kuma matsa lamba kai tsaye yana aiki akan saman gaba na diaphragm na yumbu, yana haifar da ɗan nakasar diaphragm. Ana buga masu tsayayyar fim masu kauri a bayan diaphragm na yumbu kuma an haɗa su don samar da gadar Wheatstone. Saboda tasirin piezoresistive na piezoresistive resistor, gadar tana haifar da siginar ƙarfin lantarki mai tsayi mai tsayi daidai da matsa lamba kuma kuma daidai da ƙarfin ƙarfin kuzari. An daidaita siginar daidaitaccen siginar azaman 2.0/3.0/3.3 mv/bisa ga jeri daban-daban na matsin lamba.

3. Diffused silicon pressure firikwensin: Ka'idar aiki na firikwensin matsa lamba na siliki shima ya dogara ne akan tasirin piezoresistive. Ta hanyar amfani da ka'idar sakamako na piezoresistive, matsa lamba na matsakaicin auna kai tsaye yana aiki akan diaphragm (bakin karfe ko yumbu) na firikwensin, yana haifar da diaphragm don samar da ƙananan matsuguni daidai da matsa lamba na matsakaici, don ƙimar juriya na firikwensin canje-canje. Ana gano wannan canjin ta hanyar da'irar lantarki, kuma ana canza siginar ma'auni daidai da wannan matsa lamba da fitarwa.

4. Sapphire na'urar firikwensin matsa lamba: Dangane da ka'idar aiki na juriya, ana amfani da silicon-sapphire azaman nau'i mai mahimmanci na semiconductor, wanda ke da halayen ma'auni mara misaltuwa. Sabili da haka, firikwensin semiconductor da aka yi da silicon-sapphire ba shi da hankali ga canjin zafin jiki kuma yana da kyawawan halaye na aiki har ma a babban zafin jiki. Sapphire yana da ƙarfin juriya na radiation; Bugu da kari, siliki-sapphire semiconductor firikwensin ba shi da drift pn.

5. Piezoelectric firikwensin matsin lamba: Tasirin Piezoelectric shine babban ka'idar aiki na firikwensin piezoelectric. Ba za a iya amfani da firikwensin Piezoelectric don auna a tsaye ba, saboda ana adana cajin bayan ƙarfin waje ne kawai lokacin da madauki yana da ƙarancin shigarwa mara iyaka. Wannan ba haka bane a aikace, don haka an yanke shawarar cewa firikwensin piezoelectric zai iya auna damuwa mai ƙarfi kawai.
