Ama-transmitter omfutho kawoyela asemgqenizingamathuluzi abalulekile okulinganisa umfutho kawoyela ngaphakathi kwepayipi noma isistimu, enikeza ukuqapha nokulawula ingcindezi yesikhathi sangempela. Uma kuqhathaniswa nama-transmitter okucindezela ajwayelekile, amamodeli asemgqeni akhelwe ukuhlanganiswa okungenamthungo kumzila ogelezayo ngoxhumo olunentambo noma olune-flanged, lulungele uwoyela negesi, izimoto, amasistimu asebenza ngamanzi kanye nemishini yezimboni.
Thola izidingo eziqondene nohlelo lokusebenza ngaphambi kokukhetha ama-transmitters omfutho kawoyela asemgqeni. Ukufundwa kwengcindezi elinganisiwe kuguqulwa kube amasignali kagesi futhi kuhanjiswe ohlelweni lokulawula oluhlakaniphile ukuze kuhlaziywe futhi kuqondiswe.
Izici Ezibalulekile Ezidinga Ukucatshangelwa Ngokucophelela
Ibanga lokucindezela, ukugeleza kanye ne-viscosity, ubuchwepheshe obuhlukahlukene bokuzwa, izinto ezihambisanayo kanye nesignali yokuphumayo kufanele kucatshangelwe ukuze kuqashwe okunembile nokuthembekile. Ngesikhathi esifanayo, izidingo zemvelo kanye nokuphepha kufanele zilinganiswe ukuze kuthotshelwe izindawo okuhlosiwe.
Izidingo Zohlelo Lokusebenza Lwenani
I-min kanye nengcindezi kawoyela enkulu kumapayipi inquma ukuthiuhla lwama-pressure transmittersihlanganisa la manani ukuvimbela umonakalo ongaba khona noma ukufundwa okungalungile.
Izinhlobo zokulinganisa ingcindezizihlukaniswa ngomfutho wegeji, ukucindezela okuphelele nokucindezela okuhlukile, okuhlobene nokucindezela komkhathi, i-vacuum noma umehluko phakathi kwamaphoyinti amabili ahambisanayo.
Kudingeka ama-diaphragm ashisayoi-viscous noma isiyaluyaluukugeleza ngenxa yokwesaba ukuvala noma amaphutha okulinganisa.
Ubuchwepheshe Bokuzwa Bama-Pressure Transmitters
Ama-Capacitive Transmitterszilungele izicelo ezijwayelekile, lapho kudingeka khona izisombululo zokudlulisa ukucindezela okungabizi kakhulu nokunemba okumaphakathi;
Ama-silicon transmitter ahlukanisiwezisebenza kuma-hydraulic noma ku-oyela negesi izinhlelo zokunemba okuphezulu nokuzinza kumazinga okucindezela okubanzi;
Izinto Ezivumelanayo
Khetha Isignali Yokuphuma Elungile
Okuphumayo kwesidlulisi kufanele kuhlanganiswe nohlelo lwakho lokulawula noma lokuqapha:
- 4-20 mA: Izinga lezinhlelo zokusebenza zezimboni, ezinokwethenjelwa ekudluliseleni isignali yebanga elide.
- 0-10 V: Ifanele amasistimu asekelwe kugesi, ngokuvamile asetshenziswa ekusetheni izimoto noma ezincane.
- Imiphumela Yedijithali (isb, i-HART, i-Modbus): Okuncanyelwayo kumasistimu ahlakaniphile adinga ukuxilonga noma ukulungiselelwa okukude.
Qinisekisa isignali yokuphumayo ifana nezidingo zesistimu yakho ukuze uqinisekise ukuhlanganiswa okungenazihibe.
Linganisa Izidingo Zemvelo Nezokuphepha
Ama-transmitters asemgqeni avame ukuchayeka ezimeni eziyinselele:
- Izindawo Eziyingozi: Ekusetshenzisweni kukawoyela negesi (isb., amapayipi, izindawo zokuhluzwa), khetha ama-transmitters angaqhumi noma aphephe ngokwangaphakathi aqinisekiswe ngamazinga afana ne-ATEX, FM, noma i-CSA ukuze uvimbele izingozi zokuvutha.
- I-Ingress Protection (Izilinganiso ze-IP/NEMA): Ezindaweni ezingaphandle noma ezimanzi, khetha isidlulisi esinesilinganiso se-IP esiphezulu (isb., IP67 noma i-IP68) ukuze usivikele othulini, emanzini, noma ekungeneni kukawoyela.
- Izinga Lokushisa: Qinisekisa ukuthi isidlulisi sisebenza ngaphakathi kwemikhawulo yezinga lokushisa lesistimu yakho. Ama-transmitters angaphakathi ohlelweni lokushisa eliphezulu (isb, ukuqapha uwoyela wenjini) adinga ukubekezelela ukushisa okuqinile.
Khetha Ukuxhumana Kwenqubo Elungile
Ama-transmitter asemgqeni kufanele axhume ngokuvikelekile epayipini:
- Ukuxhumana Okunemicu: Izinketho ezivamile njenge-1/4” NPT, G1/2, noma izintambo ze-M20 zilungele izinhlelo zokusebenza eziningi ezingaphakathi kwelayini Qinisekisa ukuvala okulungile (isb., O-rings noma PTFE tape) ukuze uvimbele ukuvuza.
- Izixhumanisi ezi-Flanged: Isetshenziswa kumapayipi anengcindezi ephezulu noma enobubanzi obukhulu ukuze kwehle ingcindezi ephansi kanye nokufakwa okuvikelekile.
- Ukuhambisana kosayizi wepayipi: Qinisekisa ukuthi uxhumo lomthumeli lufana nobubanzi bepayipi lakho ukuze ugweme imikhawulo yokugeleza noma izinkinga zokufaka.
Khetha uhlobo lokuxhuma oluqinisekisa ukuvuza, ukufakwa okuzinzile ngaphandle kokuphazamisa ukugeleza.
Ibhalansi Izindleko Nokusebenza
Nakuba izinto ezisezingeni eliphezulu njenge-tantalum noma ubuchwepheshe obuthuthukisiwe buthuthukisa ukuqina nokunemba, zingase zingadingeki ezinhlelweni ezingafuneki kangako. Ama-transmitters asekelwe ku-SS316L anobuchwepheshe obunamandla noma obuphiezoresistive ngokuvamile anikeza ibhalansi engabizi kakhulu. Cabangela izindleko zokuphila konke, okuhlanganisa ukunakekelwa, ukulinganisa, kanye nesikhathi sokuphumula esingaba khona, lapho uhlola izinketho. I-transmitter ethembekile inciphisa izindleko zesikhathi eside.
