Inzwa yengcindezi ye-elekthronikhi i-VG1092090311 yamafutha weloli esindayo

Yiziphi izinhlobo ezahlukene zezinzwa zokucindezela?

Kusukela kumgomo oyisisekelo, ingcindezi ingamandla aqondile asebenza endaweni engaphezulu yento. Ingcindezi = amandla/indawo. Isibonelo, i-PSI inombolo yamaphawundi ngentshi yesikwele. Noma uPascal, iNewton eyodwa ngemitha yesikwele. Kunezinhlobo ezintathu zokucindezela:

I-gauge pressure:

Lolu uhlobo oluvame kakhulu lwengcindezi lapho usebenza nezinhlelo zokusebenza zobunjiniyela. Umfutho wegeji umehluko phakathi kwengcindezi enikeziwe kanye nomfutho womkhathi. Uma ukucindezela okuphelele kungaphezu komfutho womoya, kubizwa ngokuthi i-positive overpressure. Uma ingcindezi yegeji elinganisiwe inegethivu, ibizwa ngokuthi i-negative pressure noma i-vacuum eyingxenye.

Ukucindezela okuphelele:

Leli iphuzu elingenhla kwe-vacuum ephelele. Ngokuvamile, isamba sokucindezela kwegeji kanye nomfutho womoya.

Umehluko wengcindezi: Lona umehluko phakathi kwamaphoyinti amabili lapho ingekho i-vacuum eyaziwayo noma i-vacuum ephelele.

Zonke ezinye "izinhlobo" zokucindezela (njengokucindezela okumile, ukucindezela okungalungile kanye nokwehla kweflagration) kungenye yezinketho ezingenhla, futhi amagama azo abhekisela ngokuqondile kumongo wokucindezela.

Yiziphi izinhlobo zezinzwa zokucindezela ezikhona?

Izinhlobo zezinzwa zokucindezela ziyahlukahluka kakhulu, kodwa ngokuvamile zingahlukaniswa ngokohlobo lwengcindezi (njengoba kushiwo ngenhla), indlela yokuzwa, uhlobo lwesignali yokuphumayo kanye nendawo yokulinganisa. Bheka ngayinye ngokuningiliziwe:

Indlela yokuzwa:

Umgomo wobuchwepheshe bezinzwa ulula kakhulu, okungukuthi, ukuguqula ingcindezi ekhishwe kumshini wezinzwa ibe isignali kagesi yokuphuma. Izinhlobo zezinketho zezinzwa zingabandakanya ukumelana, i-capacitive, i-resonant, i-piezoelectric, i-optical ne-MEMS. Indlela yenzwa esetshenzisiwe izothinta ukunemba, ukwethembeka, ububanzi bokulinganisa kanye nokuvumelana nezimo endaweni yokusebenza.

Izimpawu zokuphumayo:

Lawa ngokuvamile ama-transmitter, akhiqiza amandla amanje noma izinzwa futhi akhiqize i-voltage ephumayo, ehluka ngokuya ngengcindezi etholwayo.

Uhlobo lwemidiya:

Indawo yokusebenza izothinta uhlobo lwenzwa yokucindezela oyikhethayo. Isibonelo, uma inzwa yakho yokucindezela izosebenzisa imidiya ebolayo noma isebenze ohlelweni lokuhlanza in-situ noma enye indawo ehlanzekile, udinga ukukhetha ngokucophelela isisombululo esingagcina izinga eliqinile lenhlanzeko elamukelwa ngaphandle kokulinyazwa imvelo. Ilinganisa ikhambi. Okunye okucatshangelwayo kwabezindaba kufaka phakathi ukuthi ukugeleza komoya komoya, igesi, uketshezi, ukudonsa amanzi noma umoya.
