Esimweni esiyinkimbinkimbi sokulawulwa kwenqubo yezimboni—lapho ukuqapha okunembile, kwangempela kwamazinga oketshezi, aqinile, noma amdaka kubalulekile ekuphepheni kokusebenza, ukusebenza kahle, kanye nokuphathwa kwezindleko—ama-transmitter ezingeni le-radar avele njengobuchwepheshe obubalulekile. Esebenzisa izimiso zokusabalala kwamagagasi kagesi, lawa madivayisi adlula imikhawulo yamathuluzi okulinganisa amazinga endabuko (njengezinzwa ze-ultrasonic, ama-float switch, noma ama-pressure transmitter), eletha ukuthembeka okungenakuqhathaniswa ngisho nasezindaweni zezimboni ezinzima kakhulu. Kusukela ezindaweni zokuhlanza uwoyela nezitshalo zamakhemikhali kuya ezindaweni zokwelashwa kwamanzi amdaka kanye nokugcinwa kwezinsimbi ezinkulu, ama-transmitter ezingeni le-radar achaze kabusha ukuthi kusho ukuthini ukulinganisa amazinga ngokuhambisana, ukunemba, kanye nokugcinwa okuncane. Ngezansi ukuhlolwa okuphelele kwendlela yawo yokusebenza, izinzuzo ezibalulekile, kanye nomthelela wokuguqula kuzo zonke izimboni.
Enhliziyweni yokusebenza komthumeli wezinga le-radar kukhona isimiso esilula kodwa esiyinkimbinkimbi kakhulu: ukudluliselwa nokwamukelwa kwamagagasi kagesi asebenza ngesivinini esiphezulu (ngokuvamile ebangeni le-microwave, phakathi kuka-5.8 GHz no-80 GHz). Idivayisi inezingxenye ezintathu eziyinhloko: imoduli yomthumeli/owamukelayo, i-antenna, kanye neyunithi yokucubungula isignali. Umthumeli ukhiqiza isignali ye-microwave egxile, i-antenna eyikhipha ebusweni be-medium (uketshezi, okuqinile, noma i-slurry) okudingeka izinga layo lilinganiswe. Lapho la magagasi ehlangana nobuso be-medium, ingxenye yesignali ibuyiselwa emuva ku-antenna, bese idlulisela isignali eboniswayo ku-receiver. Iyunithi yokucubungula isignali ibala ukubambezeleka kwesikhathi phakathi kwamagagasi adluliselweyo naboniswayo—okwaziwa ngokuthi “isikhathi sokundiza”—futhi isebenzisa le datha, kanye nesivinini samagagasi kagesi (okungaguquki endaweni ethile), ukuze kubalwe ibanga ukusuka ku-antenna kuya ebusweni be-medium. Ngokususa leli banga ekuphakameni okuphelele kwesitsha noma ithangi, umthumeli unquma izinga eliqondile le-medium, elibe seliguqulwa libe isignali yokukhipha ejwayelekile (njenge-4–20 mA, i-HART, noma i-Modbus) yokuhlanganiswa ezinhlelweni zokulawula izinqubo. Le ndlela yokulinganisa engathintani isusa isidingo sokuxhumana ngokomzimba ne-medium, isici esisekela izinzuzo eziningi ezibalulekile zobuchwepheshe.
Enye yezinzuzo ezibaluleke kakhulu zama-radar level transmitters ukunemba kwawo okumangalisayo kanye nokuzinza kuzo zonke izimo zokusebenza ezahlukahlukene. Ama-level sensors endabuko avame ukubhekana nezici ezifana nokushintshashintsha kwezinga lokushisa, izinguquko zokucindezela, noma izakhiwo eziphakathi nendawo (isb., ubuningi, i-viscosity), okuholela ekukhukhulekeni noma ekufundeni okunganembile. Isibonelo, ama-ultrasonic sensors athembele kumaza omsindo, ijubane lawo elithonywa kakhulu izinga lokushisa lomoya, umswakama, kanye nengcindezi—okwenza angathembeki ezindaweni ezinezimo zomkhathi eziguquguqukayo. Ama-float switch, okwamanje, athambekele ekugugeni komshini, ukungcolisa, noma ukuminyana, ikakhulukazi lapho kulinganiswa uketshezi oluqinile noma izinto eziqinile ezinobukhulu bezinhlayiya ezingajwayelekile. Ama-radar level transmitters, ngokuphambene, awathinteki yilezi zici zangaphandle. Amasignali e-microwave asakazeka njalo kungakhathaliseki izinga lokushisa (kusukela ku--40°C kuya ku-200°C noma ngaphezulu, kuye ngemodeli), ingcindezi (kusukela ku-vacuum kuya emithanjeni yokucindezela okuphezulu), noma ukuba khona kothuli, umhwamuko, noma i-foam. Lokhu kuzinza kuqinisekisa ukuthi izilinganiso zihlala zinembile—ngokuvamile ngaphakathi kuka-±1 mm kuya ku-±5 mm wezinga langempela—ngisho nasezindaweni zezimboni ezibucayi. Ezimbonini ezifana namakhemikhali kaphethroli, lapho ukuqapha okunembile kwezinga loketshezi oluvuthayo kubalulekile ekuvimbeleni ukugcwala ngokweqile noma ukulimala kwemishini, lokhu kunemba akuyona nje into elula kodwa kubalulekile ekuphepheni.
Enye inzuzo ecacile ukwakheka kwazo okungathintani, okunciphisa ukulungiswa futhi kuqede umonakalo ohlobene nendawo. Ngokungafani nama-transmitter angaphansi komhlaba (okumelwe acwiliswe endaweni futhi asengozini yokugqwala, ukungcola, noma ukuvaleka) noma ama-probe omshini (angaguga noma aphuke lapho ethintana nezinto eziqinile ezirhabaxa), ama-transmitter asezingeni le-radar awalokothi ayithinte indawo elinganiswayo. I-antenna ifakwe phezulu kwethangi noma isitsha, igcina ihlukaniswe namakhemikhali agqwalisayo, ama-slurry arhabaxa, noma izinto eziqinile ezinamathelayo (njengesimende, okusanhlamvu, noma amalahle). Lokhu kuhlukaniswa kususa ingozi yomonakalo wesenzwa ngenxa yokuhlaselwa ngamakhemikhali noma ukuhuzuka ngokomzimba, kunciphisa kakhulu isidingo sokulungiswa. Azikho izingxenye ezihambayo zokugcoba, azikho ama-probe okuhlanza, futhi azikho izingxenye ezingashintshaniswa ngenxa yokuguguleka okuhlobene nendawo—ukulungiswa okuvamile kuvame ukuhilela ukuhlolwa okubonakalayo kwe-antenna njalo kanye nokuhlolwa kokulinganisa (okungenziwa njalo kude). Ezindaweni ezinamathangi afinyeleleka kalula (isb., ama-silo amade ezitshalweni zesimende) noma ezindaweni eziyingozi (isb., indawo yokugcina amakhemikhali anobuthi), lo mklamo wokulungisa ophansi uholela ekuphazamisekeni kokusebenza okumbalwa, izindleko eziphansi zomsebenzi, kanye nokuphila isikhathi eside kwenzwa (ngokuvamile iminyaka eyi-10-15, uma kuqhathaniswa neminyaka emi-3-5 yezinzwa eziningi zendabuko).
Ama-transmitter e-radar level nawo anikeza ukuguquguquka kuzo zonke izinhlobo ezahlukene zemidiya kanye nokuhlelwa kwamatangi, okwenza afaneleke cishe kuzo zonke izinhlelo zokulinganisa amazinga ezimboni. Angalinganisa ngempumelelo izinga loketshezi (kufaka phakathi ama-hydrocarbon, amakhemikhali, amanzi, kanye noketshezi oluqinile njengowoyela noma ama-molasses), izinto eziqinile (ezifana nokusanhlamvu, amapulasitiki, ama-ore, kanye nophuphu), kanye nama-slurry (njenge-sludge yamanzi amdaka noma i-mineing tailings)—ukuguquguquka okuhlangatshezwa yizinzwa zendabuko. Ngaphezu kwalokho, azivumelanisa nemiklamo ehlukahlukene yamatangi: kusukela kuma-silo amancane, amade anezithiyo zangaphakathi (njenge-agitators noma amapayipi) kuya kumatangi amakhulu, avulekile noma ngisho namachibi avulekile. Amamodeli athuthukile afaka ama-antenna akhethekile (njenge-parabolic, horn, noma ama-antenna enduku) kanye nama-algorithms okucubungula isignali (njengokucindezela i-echo) angahlunga ukubonakaliswa okuvela ezindongeni zamatangi, izakhiwo zangaphakathi, noma i-foam, okuqinisekisa ukuthi kusetshenziswa isignali kuphela eboniswa ebusweni be-medium ukuze kulinganiswe. Lokhu kuguquguquka kwenza ama-radar level transmitters abe yisisombululo esisodwa sezimboni ezahlukahlukene njengokudla neziphuzo (ukulinganisa amazinga esiraphu noma okusanhlamvu), imithi (ukuqapha izithako zamakhemikhali), ukumbiwa (ukulandelela amazinga e-ore noma i-slurry), kanye nokwelashwa kwamanzi amdaka (ukulinganisa amazinga okungcola noma i-sludge).
Okokugcina, abathumeli bezinga le-radar bahamba phambili ekuqapheni nasekuhlanganiseni okukude nezinhlelo zezimboni ezihlakaniphile, okuhambisana nokushintshela komhlaba wonke ku-Industry 4.0 kanye nokwenza izinto ngokuzenzakalela kwezimboni. Abathumeli be-radar besimanje bahlonyiswe ngezinqubo zokuxhumana zedijithali (njenge-HART 7, i-Modbus TCP/IP, i-Profinet, noma i-WirelessHART) ezivumela ukuhlanganiswa okungenamthungo nezinhlelo zokulawula ezisatshalaliswa (i-DCS), amapulatifomu okulawula nokuphatha kanye nokutholwa kwedatha (i-SCADA), kanye nesofthiwe yokuqapha esekelwe efwini. Lokhu kuvumela opharetha ukufinyelela idatha yezinga lesikhathi sangempela, izitayela zomlando, kanye nolwazi lokuxilonga kusuka noma kuphi, nganoma yisiphi isikhathi—ukuqeda isidingo sokufundwa ngesandla endaweni (okudla isikhathi, okuvame ukwenza amaphutha, futhi okuyingozi ezindaweni eziyingozi). Amamodeli amaningi afaka nezici zokuxilonga ezithuthukisiwe, njengokuziqapha ngokwakho kokungcola kwe-antenna, izixwayiso zamandla esignali, noma ukungasebenzi kahle kwehadiwe, okubangela izexwayiso ezizenzakalelayo kumaqembu okulungisa. Lokhu kuqapha okusebenzayo akugcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi kuthuthukisa ukuphepha ngokuvumela ukutholakala kwezinkinga kusenesikhathi (njengokwehla kwezinga okungalindelekile okungabonisa ukuvuza noma ukwehluleka kwephampu) ngaphambi kokuba kukhuphuke kube yizigameko ezibizayo noma eziyingozi.
Ekuphetheni, ama-radar level transmitter amelela ushintsho olujwayelekile ekulinganisweni kwezinga lezimboni. Inhlanganisela yawo yokunemba okungavamile, ukwakheka okungathintani, ukuguquguquka, ukugcinwa okuphansi, kanye namakhono okuhlanganisa ahlakaniphile abhekana nezinselele ezicindezela kakhulu zokusebenza kwezimboni zanamuhla—kusukela ekuqinisekiseni ukuphepha nokuthobela imithetho kuya ekwenzeni ngcono ukusebenza kahle kanye nokunciphisa izindleko. Njengoba izimboni ziqhubeka nokudinga izixazululo zokulawula inqubo ezithembekile, eziguquguqukayo, nezixhumene, ama-radar level transmitter azohlala ehamba phambili, enika amandla amabhizinisi ukuthi asebenze ngendlela eqhubekayo, ephephile, futhi ephumelelayo emakethe yomhlaba wonke eyinkimbinkimbi kakhulu. Kungakhathaliseki ukuthi kulinganiswa izinga likawoyela ongahluziwe ethangini lokuhlanza, okusanhlamvu esitsheni, noma udaka esitshalweni samanzi angcolile, ama-radar level transmitter aletha ukunemba nokuthembeka imboni yanamuhla engenakukwazi ukukwenza ngaphandle kwakho.
