Kwindawo enzima yolawulo lwenkqubo yemizi-mveliso—apho ukujonga ngokuchanekileyo, ngexesha langempela amanqanaba olwelo, aqinileyo, okanye amdaka kubalulekile kukhuseleko lokusebenza, ukusebenza kakuhle, kunye nolawulo lweendleko—iitransmitter zenqanaba leradar ziye zavela njengetekhnoloji eyimfuneko. Zisebenzisa imigaqo yokusasazwa kwamaza e-electromagnetic, ezi zixhobo zidlula imida yezixhobo zemveli zokulinganisa amanqanaba (ezifana nee-ultrasonic sensors, ii-float switches, okanye iitransmitter zoxinzelelo), zibonelela ngokuthembeka okungenakuthelekiswa nanto nakwiindawo ezinzima zoshishino. Ukusuka kwiindawo zokucoca ioyile kunye nezityalo zeekhemikhali ukuya kwiindawo zonyango lwamanzi amdaka kunye nokugcinwa kwezinto eziqinileyo ezinkulu, iitransmitter zenqanaba leradar zichaze ngokutsha oko kuthethwa kukulinganisa amanqanaba ngokuhambelana, ngokuchanekileyo, kunye nokugcinwa okuncinci. Apha ngezantsi kukho uphando olupheleleyo lwendlela yokusebenza kwazo, izibonelelo eziphambili, kunye nempembelelo yokuguqula kumashishini onke.
Eyona nto iphambili ekusebenzeni komthumeli we-radar level kukho umgaqo olula kodwa ophucukileyo: ukuhanjiswa kunye nokwamkelwa kwamaza e-electromagnetic ahamba rhoqo (ngesiqhelo kuluhlu lwe-microwave, phakathi kwe-5.8 GHz kunye ne-80 GHz). Esi sixhobo sineenxalenye ezintathu eziphambili: imodyuli yomthumeli/umfumani, i-antenna, kunye neyunithi yokucubungula imiqondiso. Umthumeli uvelisa isignali ye-microwave egxile, ekhutshwa yi-antenna kumphezulu we-medium (ulwelo, oluqinileyo, okanye olumdaka) ekufuneka inqanaba layo lilinganiswe. Xa la maza edibana nomphezulu we-medium, inxalenye yesignali ibuyiselwa kwi-antenna, ethi emva koko idlulisele isignali ebonakalisiweyo kumthumeli. Iyunithi yokucubungula imiqondiso ibala ixesha lokulibaziseka phakathi kwamaza adluliselweyo kunye nabonakalisiweyo—eyaziwa ngokuba “lixesha lokubhabha”—kwaye isebenzisa le datha, kunye nesantya samaza e-electromagnetic (engaguqukiyo kwi-medium ethile), ukubala umgama ukusuka kwi-antenna ukuya kumphezulu we-medium. Ngokususa lo mgama kubude obupheleleyo benqanawa okanye itanki, umthumeli umisela inqanaba elichanekileyo lesixhobo, esiguqulwa sibe sisignali esemgangathweni yokuphuma (efana ne-4–20 mA, i-HART, okanye i-Modbus) ukuze kudityaniswe kwiinkqubo zolawulo lwenkqubo. Le ndlela yokulinganisa engadibaniyo isusa isidingo sokudibana ngokwasemzimbeni nesixhobo, uphawu oluxhasa uninzi lweenzuzo eziphambili zobuchwepheshe.
Enye yezona ngenelo zibalulekileyo zee-radar level transmitters kukuchaneka kwazo okugqwesileyo kunye nokuzinza kwiimeko ezahlukeneyo zokusebenza. Ii-level sensors zemveli zihlala zinengxaki yezinto ezifana nokuguquguquka kobushushu, utshintsho loxinzelelo, okanye iimpawu eziphakathi (umz., uxinano, i-viscosity), okukhokelela ekukhukuleni okanye ekufundeni okungachanekanga. Umzekelo, ii-ultrasonic sensors zixhomekeke kumaza esandi, asantya sawo sichaphazeleka kakhulu bubushushu bomoya, ukufuma, kunye noxinzelelo—okuzenza zingathembeki kwiindawo ezineemeko zomoya eziguquguqukayo. Ii-Float switches, okwangoku, zidla ngokuguguleka ngoomatshini, zingcolise, okanye zixinene, ingakumbi xa zilinganisa ulwelo oluqinileyo okanye izinto eziqinileyo ezinobukhulu obungalinganiyo bezinto ezincinci. Ii-radar level transmitters, ngokwahlukileyo, azichaphazeleki zezi zinto zangaphandle. Imiqondiso ye-microwave isasazeka rhoqo nokuba ubushushu bunjani (ukusuka kwi--40°C ukuya kwi-200°C nangaphezulu, kuxhomekeke kwimodeli), uxinzelelo (ukusuka kwi-vacuum ukuya kwimikhumbi yoxinzelelo oluphezulu), okanye ubukho bothuli, umphunga, okanye i-foam. Olu zinzo luqinisekisa ukuba imilinganiselo ihlala ichanekile—ngokuqhelekileyo ngaphakathi kwe-±1 mm ukuya kwi-±5 mm yenqanaba lokwenyani—nakwiindawo zoshishino ezigqithisileyo. Kwimizi-mveliso efana neekhemikhali zepetrochemicals, apho ukubeka esweni ngokuchanekileyo ulwelo oluvuthayo kubalulekile ekuthinteleni ukugcwala okanye umonakalo kwizixhobo, oku kuchaneka akupheleli nje ekubeni lula kodwa kubalulekile kukhuseleko.
Enye inzuzo ebalulekileyo kuyilo lwazo lokungadibani, olunciphisa ukugcinwa nokuphelisa umonakalo onxulumene nomgangatho ophakathi. Ngokungafaniyo neetransmitter zoxinzelelo ezingaphantsi komhlaba (ezimele zifakwe kwi-medium kwaye zisengozini yokubola, ukungcoliswa, okanye ukuvaleka) okanye iiprobe zoomatshini (ezinokonakala okanye zophuke xa zidibana nezinto eziqinileyo ezirhabaxa), iitransmitter zenqanaba le-radar azikaze ziyichukumise i-medium elinganiswayo. I-antenna ifakwe phezulu kwitanki okanye kwinqanawa, igcina ikude kwiikhemikhali ezirhabaxa, ii-slurry ezirhabaxa, okanye izinto eziqinileyo ezinamathelayo (ezifana nesamente, iinkozo, okanye amalahle). Oku kwahlulwa kususa umngcipheko womonakalo wesenzi ngenxa yokuhlaselwa yikhemikhali okanye ukukrala ngokomzimba, kunciphisa kakhulu imfuneko yokugcinwa. Akukho zixhobo zishukumayo zokuthambisa, akukho probes zokuzicoca, kwaye akukho zixhobo zokuzitshintsha ngenxa yokukrala okuhambelana nomgangatho ophakathi—ukugcinwa rhoqo kubandakanya kuphela ukuhlolwa okubonakalayo kwe-antenna rhoqo kunye nokuhlolwa kokulinganisa (okunokwenziwa rhoqo kude). Kwizakhiwo ezineetanki ezifikelelekayo (umz., ii-silos ezinde kwizityalo zesamente) okanye iindawo ezinobungozi (umz., indawo yokugcina iikhemikhali ezinobungozi), olu yilo olungenakulungiswa kangako luthetha ukuphazamiseka okuncinci kokusebenza, iindleko zomsebenzi eziphantsi, kunye nobomi obude be-sensor (ngokuqhelekileyo iminyaka eli-10-15, xa kuthelekiswa neminyaka emi-3-5 kwii-sensors ezininzi zemveli).
Ii-radar level transmitters zikwabonelela ngokuguquguquka kuzo zonke iintlobo zemidiya kunye neetanki, nto leyo ezenza zifaneleke phantse kuzo zonke iindlela zokulinganisa amanqanaba emizi-mveliso. Zinokulinganisa ngokufanelekileyo amanqanaba olwelo (kuquka ii-hydrocarbons, iikhemikhali, amanzi, kunye nolwelo oluthambileyo olufana neoyile okanye ii-molasses), izinto eziqinileyo (ezifana neenkozo, iiplastiki, ii-ore, kunye neempuphu), kunye ne-slurry (ezifana ne-lidge yamanzi amdaka okanye i-mineing tailings)—ukuguquguquka okuye kwanzima ukuba kuhambelane nee-sensors zemveli. Ukongeza, ziyaziqhelanisa noyilo lweetanki ezahlukeneyo: ukusuka kwii-silos ezimxinwa, ezinde ezinemiqobo yangaphakathi (ezifana nee-agitators okanye iipayipi) ukuya kwiitanki ezinkulu, ezivulekileyo okanye kwanamachibi avulekileyo. Iimodeli eziphambili zinee-antenna ezikhethekileyo (ezifana nee-parabolic, horn, okanye ii-rod antennas) kunye ne-algorithms yokucubungula isignali (ezifana nokunciphisa i-echo) ezinokucoca ukubonakaliswa okuvela kwiindonga zetanki, izakhiwo zangaphakathi, okanye i-foam, ukuqinisekisa ukuba kuphela isignali ebonakaliswa ukusuka kumphezulu wesixhobo esetyenziselwa ukulinganisa. Olu tshintsho lwenza ukuba ii-radar level transmitters zibe sisisombululo esinye kwimizi-mveliso eyahlukeneyo njengokutya neziselo (ukulinganisa amanqanaba esiraphu okanye iinkozo), amayeza (ukujonga izithako zeekhemikhali), ukumbiwa kwemigodi (ukulandelela amanqanaba e-ore okanye i-slurry), kunye nonyango lwamanzi amdaka (ukulinganisa amanqanaba e-liff okanye i-sludge).
Okokugqibela, abathumeli benqanaba lerada bagqwesile ekujongeni nasekudibaniseni kude neenkqubo zemizi-mveliso ezikrelekrele, behambelana notshintsho lwehlabathi oluya kwi-Industry 4.0 kunye nokuzisebenzela ngokuzenzekelayo kwemizi-mveliso. Abathumeli berada banamhlanje baxhotyiswe ngeenkqubo zonxibelelwano zedijithali (ezifana ne-HART 7, i-Modbus TCP/IP, i-Profinet, okanye i-WirelessHART) ezivumela ukuhlanganiswa okungenamthungo neenkqubo zolawulo ezisasazwe (i-DCS), amaqonga olawulo lolawulo kunye nokufunyanwa kwedatha (i-SCADA), kunye nesoftware yokubeka esweni esekwe efini. Oku kuvumela abaqhubi ukuba bafikelele kwidatha yenqanaba lexesha langempela, iindlela zembali, kunye nolwazi lokuxilonga ukusuka naphi na, nangaliphi na ixesha—ukususa imfuneko yokufunda ngesandla kwindawo (ethatha ixesha, ethanda iimpazamo, kwaye inobungozi kwiindawo ezinobungozi). Iimodeli ezininzi ziquka neempawu eziphambili zokuxilonga, ezinje ngokuzijonga ngokwakho xa kukho ukungcola kwe-antenna, izilumkiso zamandla esignali, okanye ukungasebenzi kakuhle kwehardware, okubangela izilumkiso ezizenzekelayo kumaqela olondolozo. Olu hlolo olusebenzayo aluphuculi nje kuphela ukusebenza kakuhle kodwa lukwaphucula ukhuseleko ngokuvumela ukubonwa kwangoko kweengxaki (ezifana nokuhla kwamanqanaba okungalindelekanga okunokubonisa ukuvuza okanye ukusilela kwepompo) ngaphambi kokuba zikhule zibe ziziganeko ezibizayo okanye eziyingozi.
Ukuqukumbela, ii-radar level transmitters zimele utshintsho oluqhelekileyo ekulinganisweni kwenqanaba lemizi-mveliso. Ukudibana kwazo kokuchaneka okugqwesileyo, uyilo olungenanxibelelwano, ukuguquguquka, ukugcinwa okuphantsi, kunye nobuchule bokudibanisa ngobuchule kujongana nemingeni enzima kakhulu yokusebenza kwemizi-mveliso yanamhlanje—ukususela ekuqinisekiseni ukhuseleko kunye nokuthobela imithetho ukuya ekuphuculeni ukusebenza kakuhle kunye nokunciphisa iindleko. Njengoko amashishini eqhubeka nokufuna izisombululo zolawulo lwenkqubo ezinokuthenjwa, eziguquguqukayo, neziqhagamshelweyo, ii-radar level transmitters ziya kuhlala ziphambili, zinika amandla amashishini ukuba asebenze ngokuzinzileyo, ngokukhuselekileyo, nangokufanelekileyo kwimarike yehlabathi eyandayo. Nokuba zilinganisa inqanaba leoyile ekrwada kwitanki yokucocisa, iinkozo kwisisele, okanye udaka kwisityalo samanzi amdaka, ii-radar level transmitters zibonelela ngokuchaneka kunye nokuthembeka okungenakukwazi ukukuthwala ngaphandle kwemizi-mveliso yanamhlanje.
