Ama-transmitter okucindezela uwoyela angaphakathiziyizinto ezibalulekile ekulinganiseni ingcindezi kawoyela ngaphakathi kwephayiphi noma uhlelo, ezinikeza ukuqapha nokulawula ingcindezi ngesikhathi sangempela. Uma kuqhathaniswa nama-transmitter ajwayelekile okucindezela, amamodeli angaphakathi aklanyelwe ukuhlanganiswa okungenamthungo endleleni yokugeleza ngokuxhumeka okunezintambo noma okune-flange, okulungele uwoyela negesi, izimoto, izinhlelo ze-hydraulic kanye nemishini yezimboni.
Thola izidingo ezithile zesicelo ngaphambi kokukhetha ama-transmitter engcindezi kawoyela angaphakathi. Ukufundwa kwengcindezi okulinganisiwe kuguqulwa kube amasignali kagesi bese kulethwa ohlelweni lokulawula oluhlakaniphile ukuze kuhlaziywe futhi kulawulwe.
Izinto Ezibalulekile Ezidinga Ukucatshangelwa Ngokucophelela
Ububanzi bokucindezela, ukugeleza kanye ne-viscosity, ubuchwepheshe obuhlukahlukene bokuzwa, izinto ezihambisanayo kanye nesignali yokuphuma kufanele kucatshangelwe ukuze kuqashwe ngokunembile nangokuthembekile. Ngesikhathi esifanayo, izidingo zemvelo nokuphepha kufanele zilinganiswe ngokuhambisana nezindawo eziqondiwe.
Izidingo Zesicelo Senani
Ukucindezela kukawoyela okuncane kanye nokuphezulu kumapayipi kunquma ukuthiububanzi bama-transmitter okucindezelaihlanganisa la manani ukuvimbela umonakalo ongaba khona noma ukufundwa okunganembile.
Izinhlobo zokulinganisa ingcindezizihlukaniswe ngengcindezi yokulinganisa, ingcindezi ephelele kanye nengcindezi yokuhlukanisa, zihlobene nengcindezi yomoya, i-vacuum noma umehluko phakathi kwamaphuzu amabili ahambisanayo.
Kudingeka ama-diaphragm okuhlanzaokuqinile noma okuguquguqukayoukugeleza ngenxa yokwesaba ukuvaleka noma amaphutha okulinganisa.
Ubuchwepheshe Bokuzwa Kwabathumeli Bokucindezela
Ama-transmitter anamandlazifanele ukusetshenziswa kwezinhloso ezijwayelekile, lapho kudingeka khona izixazululo zokudlulisa ingcindezi ezingabizi kakhulu nezinembile ngokumaphakathi;
Ama-transmitter e-silicon asakazekilezisebenza ezinhlelweni ze-hydraulic noma ze-oyili negesi ukuze kube nokunemba okuphezulu kanye nokuqina ebangeni elibanzi lokucindezela;
Izinto Ezihambisanayo
Khetha Isignali Yokukhipha Efanele
Umphumela womthumeli kumele uhlangane nohlelo lwakho lokulawula noma lokuqapha:
- 4-20 mA: Izinga elijwayelekile lezinhlelo zokusebenza zezimboni, elithembekile ekudlulisweni kwesignali ebangeni elide.
- 0-10 V: Kufanelekela izinhlelo ezisekelwe ku-voltage, ezivame ukusetshenziswa ezimotweni noma kumasethingi amancane.
- Imiphumela Yedijithali (isb., i-HART, i-Modbus): Kukhethwa izinhlelo ezihlakaniphile ezidinga ukuxilongwa noma ukucushwa okukude.
Qinisekisa ukuthi isignali yokukhipha ihambisana nezidingo zesistimu yakho ukuqinisekisa ukuhlanganiswa okungenamthungo.
Hlola Izidingo Zemvelo Nokuphepha
Ama-transmitter angaphakathi avame ukuchayeka ezimweni ezinzima:
- Izindawo Eziyingozi: Ezisetshenzisweni zikawoyela negesi (isb., amapayipi, izindawo zokuhluza), khetha ama-transmitter angaqhumi noma aphephile ngokwemvelo aqinisekiswe yizindinganiso ezifana ne-ATEX, FM, noma i-CSA ukuvimbela izingozi zokusha.
- Ukuvikelwa Kokungena (Izilinganiso ze-IP/NEMA): Ezindaweni ezingaphandle noma ezimanzi, khetha i-transmitter enesilinganiso se-IP esiphezulu (isb., IP67 noma IP68) ukuze ivikeleke ekungeneni kothuli, amanzi, noma uwoyela.
- Ibanga Lokushisa: Qinisekisa ukuthi i-transmitter isebenza ngaphakathi kwemikhawulo yokushisa yesistimu yakho. Ama-transmitter angaphakathi kwemigqa ekusetshenzisweni kokushisa okuphezulu (isb., ukuqapha uwoyela wenjini) adinga ukubekezelela ukushisa okuqinile.
Khetha Uxhumano Lwenqubo Olufanele
Ama-transmitter angaphakathi kumele axhumeke ngokuphephile epayipini:
- Ukuxhumeka Okunezintambo: Izinketho ezivamile njengezintambo ze-NPT eziyi-1/4”, i-G1/2, noma i-M20 zifaneleka kakhulu ezinhlelweni eziningi ezingaphakathi. Qinisekisa ukuvala kahle (isb., ama-O-rings noma i-PTFE tape) ukuze uvimbele ukuvuza.
- Ukuxhumeka Okune-Flanged: Isetshenziswa kumapayipi anomfutho ophezulu noma amakhulu ukuze kwehliswe umfutho ophansi futhi kufakwe ngokuphephile.
- Ukuhambisana Kosayizi Wepayipi: Qinisekisa ukuthi uxhumano lomthumeli luhambisana nobubanzi bepayipi lakho ukuze ugweme imikhawulo yokugeleza noma izinkinga zokufakwa.
Khetha uhlobo loxhumano oluqinisekisa ukufakwa okuqinile nokungavuzi ngaphandle kokuphazamisa ukugeleza kwamanzi.
Izindleko Zokulinganisela Nokusebenza
Nakuba izinto ezisezingeni eliphezulu njenge-tantalum noma ubuchwepheshe obuthuthukisiwe zithuthukisa ukuqina nokunemba, zingase zingadingeki ezinhlelweni zokusebenza ezingabizi kakhulu. Ama-transmitter asekelwe ku-SS316L anobuchwepheshe be-capacitive noma be-piezoresistive avame ukunikeza ibhalansi engabizi kakhulu. Cabanga ngezindleko zokuphila konke, okuhlanganisa ukulungiswa, ukulinganiswa, kanye nesikhathi sokungasebenzi esingaba khona, lapho uhlola izinketho. I-transmitter ethembekile inciphisa izindleko zesikhathi eside.
