Inzwa yokucindezela kwamanzi uhlobo lweinzwa yokucindezelaesetshenziswa kakhulu ekusebenzeni kwezimboni. Kusetshenziswa kabanzi ezindaweni ezahlukahlukene ezenzakalelayo zezimboni, ukulondolozwa kwamanzi kanye ne-hydropower Engineering, izinto zokuhamba nezokwakha, izinhlelo ze-automation zokukhiqiza, ubuchwepheshe bomkhumbi, amapayipi okuhambisa kanye nezinye izindawo.
Inzwa yengcindezi yamanzi iyithuluzi lokutholwa elingazwa imininingwane elilinganisiwe, futhi lingaguqula imininingwane ebukeziwe ibe amasiginali kagesi noma ezinye izinhlobo ezidingekayo zokukhishwa kwemininingwane ngokuya ngemithetho. , Isitoreji, ukubonisa, ukuqopha kanye nezidingo zokulawula. Kuyisixhumanisi sokuqala ukuqaphela ukutholwa nokulawula okuzenzakalelayo.
Isebenza kanjani inzwa yokucindezela kwamanzi:
Umnyombo wenzwa yengcindezelo yamanzi uvame ukwenziwa nge-silicon esetshenzisiwe. Isimiso esisebenzayo ukuthi ingcindezi yokucindezela kwamanzi okulinganiselwe isebenza ngokuqondile kudayali yenzwa, okwenza i-diaphragm ikhiqize ngokulandelana kwenhloso yamanzi, futhi ukuguqula inani lokumelana ne-sensor kuguqulwe, kanye nokukhipha isibonakaliso sokulinganisa okuhambelana nengcindezi.
Isici se-static se-sensor sisho ubudlelwano phakathi kokukhishwa kwenzwa kanye nokufakwa kwesiginali yokufaka ye-static. Ngoba okokufaka nokukhipha azimele ngesikhathi ngalesi sikhathi, ubudlelwano phakathi kwabo, okungukuthi, izici zezinzwa, kungaba yi-abcissa eguquguqukayo, futhi okufakiwe kusetshenziswa njenge-abcissa edonswa yi-oda kuchaziwe. Amapharamitha asemqoka abonisa izici ze-static zenzwa yilezi: ulayini, ukuzwela, i-hysteresis, ukuphindaphindwa, ukudonsa, njll.
. Kuchazwa njengesilinganiso senani eliphakeme lokuphambuka phakathi kwejika lesimilo langempela kanye nomugqa oqondile oqondile kwinani eliphelele lokukhipha kububanzi obugcwele
(2) Ukuzwela: Ukuzwela kuyinkomba ebalulekile yezimpawu zezinzwa. Kuchazwa njengesilinganiso sokukhuphuka kwenani lokuphuma kokukhuphuka okuhambisanayo kwenani lokufaka elibangele ukukhuphuka. Ukuzwela kudonswa nguS.
. Ngokwesiginali yokufaka ngosayizi ofanayo, amasiginali wokukhipha ama-stroke adluliselwe phambili nawokubuyisela emuva wenzwa awalingani ngosayizi, futhi lo mehluko ubizwa ngokuthi umehluko we-hysteresis.
.
. Kunezizathu ezimbili ze-Drift: Eyokuqala amapharamitha ahlelekile enzwa uqobo; Enye indawo ezungezile (njengokushisa, umswakama, njll.).
Izici ezinamandla
Izici ezibizwa ngokuthi amandla ashukumisayo zibhekisela kwizimpawu zokukhishwa kwenzwa lapho kufakwa khona izinguquko. Ngomsebenzi osebenzayo, izici ezinamandla zenzwa zivame ukuvezwa ngokuphendula kwayo kwezinye izimpawu zokufaka ezijwayelekile. Lokhu kungenxa yokuthi ukuphendula kwenzwa esigcawini sokufaka okujwayelekile kulula ukuthola izilingo, futhi kunobudlelwano obuthile phakathi kokuphendula okujwayelekile kusizinda lokufaka esiteji kanye nanoma yisiphi isiginali yayo, futhi okugcina kungafakwa ngokwazi okwedlule. Izimpawu ezijwayelekile zokufaka ezisetshenziswa kakhulu yizimpawu zesinyathelo sesinyathelo nesibonakaliso se-sinousoidal, ngakho-ke izici ezinamandla zenzwa zivame ukuvezwa ngempendulo yesinyathelo kanye nokuphendula imvamisa.
