- Isingeniso
Isidlulisi sokulinganisa izinga likaketshezi iyithuluzi elinikeza ukulinganisa okuqhubekayo kwezinga loketshezi.Ingasetshenziselwa ukunquma izinga lokuqinile okuwuketshezi noma okuyinqwaba ngesikhathi esithile.Ingakwazi ukukala ileveli yoketshezi yemidiya efana namanzi, uketshezi lwe-viscous namafutha, noma imidiya eyomile efana nenqwaba yezinto eziqinile nezimpushana.
Umshini wokulinganisa uketshezi ungasetshenziswa ezimeni ezehlukene zokusebenza njengeziqukathi, amathangi ngisho nemifula, amachibi nemithombo.Lawa ma-transmitters avame ukusetshenziswa ekuphatheni impahla, ukudla nesiphuzo, amandla, amakhemikhali, nezimboni zokuhlanza amanzi.Manje ake sibheke amamitha wezinga le-liquid amaningana avame ukusetshenziswa.
- Inzwa yeleveli engaphansi kwamanzi
Ngokusekelwe kumgomo wokuthi ingcindezi ye-hydrostatic ilingana nobude boketshezi, inzwa yeleveli engaphansi kwamanzi isebenzisa umphumela we-piezoresistive we-silicon ehlukanisiwe noma inzwa ye-ceramic ukuguqula ingcindezi ye-hydrostatic ibe isignali kagesi.Ngemuva kwesinxephezelo sezinga lokushisa nokulungiswa komugqa, iguqulelwa ku-4-20mADC okukhishwayo kwesignali yamanje evamile.Ingxenye yenzwa ye-submersible hydrostatic pressure transmitter ingafakwa ngqo oketshezini, kanti ingxenye yokudlulisela ingalungiswa nge-flange noma ubakaki, ukuze kube lula kakhulu ukuyifaka nokusebenzisa.
Inzwa yezinga elingaphansi kwamanzi yenziwe ngohlobo oluthuthukisiwe lokuzihlukanisa olusabalalisiwe lwesici esibucayi se-silicon, esingafakwa ngokuqondile esitsheni noma emanzini ukuze kukalwe ngokunembile ubude kusukela ekugcineni kwenzwa kuya endaweni yamanzi, futhi kukhiphe izinga lamanzi ngokusebenzisa i-4 - 20mA yamanje. noma isignali ye-RS485.
- Inzwa yezinga likaMazibuthe
Isakhiwo se-flap samagnetic sisekelwe kumgomo wepayipi lokudlula.Izinga le-liquid epayipini elikhulu lihambisana nalokho okusesitsheni sesitsha.Ngokomthetho we-Archimedes, i-buoyancy ekhiqizwa ukuntanta kazibuthe oketshezini kanye nebhalansi yamandla adonsela phansi kuntanta ezingeni loketshezi.Lapho izinga loketshezi lomkhumbi elilinganisiwe likhuphuka futhi lehla, ukuntanta okujikelezayo epayipini elikhulu lemitha yezinga le-liquid nakho kuyakhuphuka futhi kwehle.Insimbi kazibuthe ehlala njalo kuntanta ishayela ikholomu ebomvu nemhlophe kusibonisi ukuthi iphendukele ku-180 ° ngeplathifomu yokuhlanganisa kazibuthe.
Lapho izinga le-liquid likhuphuka, ukuntanta kuyashintsha kusuka kumhlophe kuya kokubomvu.Lapho izinga le-liquid liwela, ukuntanta kuyashintsha kusuka kokubomvu kuya kokumhlophe.Umngcele omhlophe-obomvu ubude bangempela bezinga loketshezi lwento emaphakathi esitsheni, ukuze kubonakale inkomba yezinga loketshezi.
- Inzwa yezinga le-liquid ezizibuthe
Isakhiwo senzwa yeleveli yoketshezi eyi-magnetostrictive siqukethe ithubhu lensimbi engagqwali (induku yokulinganisa), intambo yamagnetostrictive (intambo ye-waveguide), iflothi ehambayo (nozibuthe ongunaphakade ngaphakathi), njll. Uma inzwa isebenza, ingxenye yesekhethi yenzwa izojabulisa ukushaya kwenhliziyo. yamanje kuntambo ye-waveguide, kanye ne-pulse yamanje kazibuthe izokhiqizwa eduze kwentambo ye-waveguide lapho yamanje ibhebhetheka ngocingo lwe-waveguide.
I-float ihlelwa ngaphandle kwenduku yokulinganisa yenzwa, futhi ukuntanta kuhamba phezulu naphansi eduze kwenduku yokulinganisa ngokushintsha kwezinga loketshezi.Kukhona isethi yezindandatho kazibuthe unomphela ngaphakathi kokuntanta.Lapho i-pulsed yamanje kazibuthe ihlangana nendandatho kazibuthe eyindandatho ekhiqizwe ukuntanta, inkambu kazibuthe ezungeze indawo entantayo iyashintsha, ukuze intambo ye-waveguide eyenziwe ngezinto ezithinta kazibuthe ikhiqize i- torsional wave pulse endaweni yokuntanta.Ukushaya kwenhliziyo kudluliselwa emuva ngocingo lwe-waveguide ngesivinini esinqunyiwe futhi kutholwa indlela yokuthola.Ngokulinganisa umehluko wesikhathi phakathi kokudlulisa i-pulse current kanye ne-torsional wave, indawo yokuntanta inganqunywa ngokunembile, okungukuthi, indawo ye-liquid surface.
- Inzwa Yezinga Lokubalulekile Lokungena Kwe-Radio Frequency Admittance
Ukwamukela amaza omsakazo ubuchwepheshe obusha bokulawula izinga obuthuthukisiwe kusukela kulawulo lweleveli ye-capacitive, obuthembeke kakhulu, obunemba kakhudlwana futhi obusebenza kakhulu.Iwukuthuthukiswa kobuchwepheshe bokulawula izinga le-capacitive.
Lokhu okubizwa ngokuthi i-radio frequency admittance isho ukuphindaphinda kokuvinjwa kukagesi, okuhlanganisa ingxenye ephikisayo, ingxenye ye-capacitive kanye nengxenye ye-inductive.Ifrikhwensi yomsakazo i-spectrum yamaza omsakazo wemitha yezinga loketshezi olunemvamisa ephezulu, ngakho-ke ukuvuma kwefrikhwensi yomsakazo kungaqondwa njengokuvuma ukukala ngamagagasi omsakazo amaza aphezulu.
Uma ithuluzi lisebenza, inzwa yensimbi yakha inani lokungena ngodonga nendawo ekalilwayo.Lapho izinga lezinto ezibonakalayo lishintsha, inani lokuvuma liyashintsha ngokufanele.Iyunithi yesekethe iguqula inani lokuvuma elilinganisiwe libe okukhiphayo kwesignali yeleveli yokubalulekile ukuze kubonwe isilinganiso seleveli ebalulekile.
- Imitha yezinga le-ultrasonic
Imitha yezinga le-Ultrasonic iyithuluzi lezinga ledijithali elilawulwa yi-microprocessor.Esilinganisweni, i-pulse ultrasonic wave ithunyelwa inzwa, futhi igagasi lomsindo litholwa inzwa efanayo ngemva kokuboniswa indawo engaphezulu, bese liguqulwa libe isignali kagesi.Ibanga phakathi kwenzwa nento evivinywayo libalwa ngesikhathi phakathi kokudlulisa nokwamukela kwegagasi lomsindo.
Izinzuzo aziyona ingxenye egudlukayo engumshini, ukwethembeka okuphezulu, ukufakwa okulula nokulula, ukulinganisa okungathinteki, futhi akuthintwa i-viscosity kanye nokuminyana koketshezi.
Okubi ukuthi ukunemba kuphansi, futhi ukuhlolwa kulula ukuba nendawo eyimpumputhe.Akuvunyelwe ukukala umkhumbi wokucindezela kanye ne-volatile medium.
- Imitha yezinga lerada
Imodi yokusebenza yemitha yezinga le-radar liquid idlulisa ukubonisa ukwamukela.I-antenna yemitha yeleveli yoketshezi ye-radar ikhipha amagagasi kagesi, abonakala ebusweni bento elinganisiwe bese etholwa uthi.Isikhathi samagagasi kagesi ukusuka ekudluliseleni kuya kokwamukela silingana nebanga lezinga le-liquid.Imitha yeleveli ye-radar liquid irekhoda isikhathi samagagasi okushaya kwenhliziyo, futhi isivinini sokudlulisa samagagasi kagesi asishintshi, bese kubalwa ibanga elisuka ezingeni loketshezi ukuya othini lwe-radar, ukuze kwaziwe izinga loketshezi lweleveli yoketshezi.
Ekusetshenzisweni okungokoqobo, kunezindlela ezimbili zemitha yezinga le-radar liquid, okuyi-frequency modulation wave wave kanye ne-pulse wave.Imitha yeleveli ye-liquid enobuchwepheshe obuqhubekayo begagasi obuguquliwe busebenzisa amandla aphezulu, isistimu yezintambo ezine kanye nesekethe ye-elekthronikhi eyinkimbinkimbi.Imitha yezinga le-liquid enobuchwepheshe be-radar pulse wave isebenzisa amandla aphansi, inganikwa amandla uhlelo lwezintambo ezimbili ze-24 VDC, kulula ukufeza ukuphepha kwangaphakathi, ukunemba okuphezulu kanye nobubanzi besicelo esibanzi.
- Imitha yezinga le-radar yamagagasi aqondisiwe
Isimiso sokusebenza sesidlulisi sezinga le-radar yegagasi eliqondisiwe siyefana naleso segeji yeleveli ye-radar, kodwa sithumela ama-microwave pulses ngekhebula lenzwa noma induku.Isignali ishaya indawo ewuketshezi, bese ibuyela kunzwa, bese ifika endaweni yesidlulisi.Izinto zikagesi ezididiyelwe endlini yesidluliseli zinquma ileveli yoketshezi ngokusekelwe esikhathini esisithathayo ukuze isignali ihambe nenzwa futhi ibuye futhi.Lezi zinhlobo zama-level transmitters zisetshenziswa ezinhlelweni zezimboni kuzo zonke izindawo zobuchwepheshe benqubo.
