Lapho ukhetha imitha yezinga lezinga le-ultrasonic-ubufakazi bokuqhuma, izici ezilandelayo ezibalulekile zidinga ukucatshangelwa.Owokuqala uhla lokulinganisa, ububanzi bokulinganisa bezinto zokusebenza bungamamitha angu-0-15, obufanele izidingo zokulinganisa zamazinga ahlukene oketshezi esitsheni.Okwesibili izinga lokushisa elizungezile, imitha yezinga lezinga le-ultrasonic-ubufakazi bokuqhuma ingasebenza ngokujwayelekile endaweni enzima ye -40 ° C kuya ku-+60 ° C ukuze kuqinisekiswe ukwethembeka nokuzinza kwemishini.Izinga lokuvikela nalo liwukucatshangelwa okubalulekile, futhi okokusebenza kuhambisana nesigaba sokuvikela ukuqhuma i-ExdIICT6, esifanele ukutholwa kwezinga loketshezi ezindaweni ezivuthayo neziqhumane.Ngaphezu kwalokho, isignali yokuphumayo ingesinye isici esidinga ukunakwa.Imitha yezinga le-ultrasonic-proof-proof inikeza izindlela ezimbili zokuphuma ze-4-20mA isignali ye-analog kanye nesignali yedijithali ye-RS485, elungele ukulawula ukuxhumanisa nezinye izinto zokusebenza.Mayelana nemodi yokuguqula, idivayisi isebenzisa imodi yokuguqula yeziteshi ezimbili ukuze kuzuzwe ukudluliswa kwezimpawu zokulinganisa ohlangothini olukabili kanye nokutholwa okuphindaphindiwe ukuze kuqinisekiswe ukunemba nokuthembeka kokulinganisa.Izidingo zokunemba nazo zingenye yezinto okudingeka zicatshangelwe lapho kukhethwa, imitha yezinga le-ultrasonic-proof-proof inamandla okulinganisa okunemba okuphezulu, ukunemba okungu-±0.5%, ukuze kuhlangatshezwane nezidingo zokulinganisa ezinembile enqubweni yokukhiqiza.Ekugcineni, indlela yokufaka, imishini inikeza ukufakwa ohlangothini, ukufakwa okuphezulu kanye nohlobo lwe-flange izindlela zokufaka ezintathu, ungakhetha indlela yokufaka efanele ngokusho kwesimo sangempela.
Ngaphezu kwezici zokukhetha, imingcele yezobuchwepheshe yemitha yezinga le-ultrasonic-ubufakazi bokuqhuma nayo idinga ukuqondwa.I-voltage yokusebenza yedivayisi ingakhethwa i-AC220V noma i-DC24V, imvamisa yokusebenza ingu-20-100kHz, isikhathi sokuphendula amasekhondi angu-1.5, futhi isikhathi sokulibaziseka kwesignali imizuzwana engu-2.5.Ngokuphathelene nezivumelwano zokuxhumana, sekela imigomo ye-Modbus ne-Hart.Imidiya esebenzayo ihlanganisa uketshezi nokuqinile.Iphutha lesistimu ngu-±0.2%, futhi amandla okuvimbela ukuphazamiseka afinyelela ku-80dB.
Imitha yezinga le-ultrasonic-proof-proof isetshenziswa kabanzi kumakhemikhali, i-petrochemical, i-metallurgy, amandla kagesi, ukwelashwa kwamanzi neminye imikhakha.Ingasetshenziselwa ukuthola izinga loketshezi lamathangi okugcina, ama-reactor, amapayipi, amathangi okugcina kanye nama-transformer.Embonini yamakhemikhali, ingaqinisekisa ukugcinwa okuphephile nokuthuthwa koketshezi oluhlukahlukene;Embonini ye-metallurgical, ingakwazi ukuqapha izinga lamanzi lemidiya yamakhemikhali nemikhiqizo kawoyela;Embonini yamandla, ingasetshenziselwa ukuqapha izinga le-transformer;Embonini yokuhlanza amanzi, angasetshenziswa ukuhlanza indle kanye nokuqapha izinga lokuhlinzekwa kwamanzi omthombo.Ngaphezu kwalokho, ibuye ilungele ukuqapha izinga le-liquid kanye nokuqapha izinga kwezinye izimboni.
