Abathumeli boxinzelelo lweoyile ngaphakathizizixhobo eziyimfuneko kumlinganiselo we-oyile yoxinzelelo ngaphakathi kombhobho okanye inkqubo, enikezela ngokujongwa kwexesha lokwenyani kunye nolawulo. Xa kuthelekiswa nokuhanjiswa koxinzelelo oluqhelekileyo, iimodeli ezingaphakathi zenzelwe ukudityaniswa ngokungenamthungo kwindlela yokuhamba ngoqhagamshelo oludityanisiweyo okanye olune-flanged, lulungele ioyile kunye negesi, iimoto, iinkqubo zehydraulic kunye noomatshini bemizi-mveliso.
Bonisa iimfuno ezicacileyo zesicelo ngaphambi kokuba ukhethe ii-oyile ezihambisa uxinzelelo lwe-oyile. Imilinganiselo yoxinzelelo olulinganisiweyo iguqulwa ibe yimiqondiso yombane kwaye ihanjiswe kwinkqubo yokulawula ehlakaniphile ukuhlalutya ngakumbi kunye nokulawulwa.
Imiba Ebalulekileyo Efuna Ukuqwalaselwa Ngenyameko
Uluhlu loxinzelelo, ukuhamba kunye ne-viscosity, itekhnoloji ehlukeneyo yokubona, izinto ezihambelanayo kunye nomqondiso wemveliso kufuneka zithathelwe ingqalelo ukujonga ngokuchanekileyo nokuthembekileyo. Kwangaxeshanye, iimfuno zokusingqongileyo kunye nokhuseleko kufuneka zixatyiswe ukuthotyelwa kweendawo ekujoliswe kuzo.
IiMfuno zeSicelo seXabiso
Imin kunye noxinzelelo lweoyile enkulu kwimibhobho imisela ukubauluhlu lwabadlulisi boxinzeleloigubungela la maxabiso ukuthintela umonakalo onokwenzeka okanye ufundo olungachanekanga.
Iindidi zokulinganisa uxinzelelozihlelwe kuxinzelelo lwe-gauge, uxinzelelo olupheleleyo kunye noxinzelelo oluhlukeneyo, olunxulumene noxinzelelo lwe-atmospheric, i-vacuum okanye umahluko phakathi kwamanqaku amabini ahambelanayo.
I-diaphragms egungxulwayo iyafuneka ngaphakathii-viscous okanye isiphithiphithiukuqukuqela ngenxa yokoyika ukuvala okanye iimpazamo zomlinganiselo.
IiTekhnoloji zokuva iiMveliso zoThutho loxinzelelo
Ii-Capacitive transmitterszifanelekile kwizicelo zenjongo jikelele, apho iindleko-esebenzayo kunye nezimodareyitha zokuchaneka kwezisombululo zokuhambisa uxinzelelo ziyafuneka;
Iitransmitha zesilicon ezisasazekileyozisebenza kwiinkqubo ze-hydraulic okanye i-oyile kunye negesi yokuchaneka okuphezulu kunye nokuzinza kwiindidi zoxinzelelo olubanzi;
Izinto ezihambelanayo
Khetha Umqondiso Wesiphumo Sasekunene
Imveliso ye-transmitter kufuneka idityaniswe nolawulo lwakho okanye inkqubo yokubeka iliso:
- 4-20 mA: Umgangatho wokusetyenziswa kwemizi-mveliso, ethembekileyo yokuhanjiswa komqondiso omde.
- 0-10 V: Ifanelekile kwiinkqubo ezisekelwe kumbane, zihlala zisetyenziswa kwiimoto okanye kwiiseti ezincinci.
- Iziphumo zeDijithali (umz., HART, Modbus): Ikhethwa kwiinkqubo ezihlakaniphile ezifuna ukuxilongwa okanye uqwalaselo olukude.
Qinisekisa isignali yemveliso ihambelana neemfuno zesixokelelwano sakho ukuze uqinisekise indibaniselwano engenamthungo.
Vavanya imo engqongileyo kunye neeMfuno zoKhuseleko
Abathumeli be-inline bahlala bevezwa kwiimeko ezinzima:
- Iindawo ezinobungozi: Kusetyenziso lwe-oyile nerhasi (umzekelo, imibhobho, iindawo zokucokisa), khetha izinto ezinokuthi zingaqhushumba okanye zikhuseleke ngokwangaphakathi eziqinisekiswe ngokwemigangatho efana ne-ATEX, FM, okanye i-CSA ukunqanda ubungozi bokutsha.
- Ukhuseleko lokuNgena (Imilinganiselo ye-IP/NEMA): Kwiindawo ezingaphandle okanye ezimanzi, khetha isidluliseli esinomlinganiselo ophezulu we-IP (umzekelo, IP67 okanye IP68) ukukhusela eluthulini, emanzini, okanye ekungeneni kwe-oyile.
- Uluhlu lobushushu: Qinisekisa ukuba isidluliseli sisebenza ngaphakathi kwemida yobushushu benkqubo yakho. Ii-inline transmitters kwi-high-temperature applications (umzekelo, ukujonga i-oyile ye-injini) zifuna ukunyamezela ubushushu obuqinileyo.
Khetha uQhakamshelwano lweNkqubo eLungileyo
Abathumeli abangaphakathi kufuneka baqhagamshele ngokukhuselekileyo kumbhobho:
- Uqhagamshelo olunemisonto: Iinketho eziqhelekileyo ezifana ne-1/4” NPT, G1/2, okanye i-M20 imisonto ilungele uninzi lwezicelo ezingaphakathi.
- Uxhulumaniso lweFlanged: Isetyenziswe kwimibhobho yoxinzelelo oluphezulu okanye i-diameter enkulu yoxinzelelo oluphantsi kunye nokufakwa okukhuselekileyo.
- Ukuhambelana kobungakanani bombhobho: Qinisekisa uqhagamshelo lomthumeli uhambelana nedayamitha yombhobho wakho ukunqanda izithintelo zokuhamba okanye imiba yofakelo.
Khetha uhlobo lokudibanisa oluqinisekisa ukuvuza-ubungqina, ukufakwa okuzinzileyo ngaphandle kokuphazamisa ukuhamba.
Iindleko zokulinganisela kunye nokuSebenza
Ngelixa izixhobo eziphezulu ezifana ne-tantalum okanye itekhnoloji ephucukileyo iphucula ukuqina kunye nokuchaneka, zisenokungafuneki kwizicelo ezingafuneki kangako. I-SS316L-based transmitters ene-capacitive okanye iteknoloji ye-piezoresistive ihlala inika ibhalansi eneendleko. Qwalasela iindleko zobomi bonke, kubandakanywa ulungiso, ulungelelwaniso, kunye nexesha lokuphumla elinokubakho, xa uvavanya iinketho. Isidluliseli esithembekileyo sinciphisa iindleko zexesha elide.
