Ukulinganisa izinga lokushisa kuyisici esibalulekile sokulawulwa kwenqubo kuzo zonke izinhlobo ezibanzi zezimboni ezifana nokukhiqiza amakhemikhali, uwoyela negesi, ezemithi, nokukhiqizwa kokudla. Inzwa yezinga lokushisa iyithuluzi elibalulekile elikala amandla ashisayo ngokuqondile futhi lihumushe ukunyakaza kwezinga lokushisa libe amasignali kagesi ukuze kuzuzwe ukuqapha okuqhubekayo nokuqoqwa kwedatha yokuthi ingabe inqubo iyasebenza ngaphakathi kwesikophu sezinga lokushisa esichaziwe. Njengoba kushiwo kuSingakwazi ukufaka esikhundleni se-RTD nge-Thermocouple?, izici ezijwayelekile zokuzwa izinga lokushisa zifaka i-RTD ne-TR, esebenza kahle kakhulu esilinganisweni esihlukile sokulinganisa kanye nesignali ye-ohm/mV ephumayo ngokuhlukana.
Nakuba inzwa yezinga lokushisa sekuyisikhathi eside isebenza njengedivayisi eyisisekelo yokuthwebula idatha eshisayo izimele, ingahlanganiswa kumasistimu okusakaza kuzinhlelo zokusebenza zokulawula inqubo. I-Temperature Transmitter iyidivayisi ephakathi exhuma ku-RTD noma inzwa ye-thermocouple, ikhulise futhi ikhulise isignali yenzwa enesimo kusignali kagesi emisiwe, bese iphumela ekutholeni izinto zikagesi. Amasignali anesimo afundelwa ukusetshenziswa isistimu yokulawula engemuva njenge-PLC noma i-DCS ngokuvamile ayi-analog 4-20mA kanye ne-digital Hart noma ukuxhumana kwe-Modbus.
Izinzuzo zokusebenzisa i-transmitter yezinga lokushisa
Nakuba izinzwa zezinga lokushisa zihlala zibalulekile ekutholweni kwedatha, izidluliseli ziphakamisa ukusetshenziswa kwazo ngokuthuthukiswa okumbalwa:
Ubuqotho besignali obuthuthukisiwe:Isignali yamandla kagesi amancane kusekethe ekhiqizwa inzwa yokushisa iyodwa ibuthakathaka futhi isengozini yomsindo kagesi nokuphazamiseka kanye nokuwohloka kwesignali ebangeni elide. Uma kuqhathaniswa, isiginali ye-4-20mA elawulwa yi-transmitter iqine kakhulu futhi yenza kube lula ukumelana nokuphazamiseka kazibuthe. Ukwenziwa komugqa kanye nesinxephezelo sokuphuma kwenzwa eluhlaza kwenza ukudluliswa kwedatha kuye kudivayisi yokulawula kunembe kakhulu futhi kuthembeke.
Ukuhambisana nokuba lula:Imojula yesidlulisi sezinga lokushisa iyahambisana nazo zombili izinzwa ze-RTD kanye ne-thermocouple. Ukusetshenziswa kwezinto eziningi zokuzwa nakho kungamukeleka. I-versatility yenza i-transmitter isetshenziswe kabanzi kuzo zonke izinhlobo zokulinganisa izinga lokushisa nge-span ehlukene nezidingo zobuningi benzwa. Isibonisi esisendaweni singabekwa ebhokisini letheminali elinikeza ukufundwa kwendawo okufundekayo nokucushwa.
Ukuhlanganiswa kwesistimu okuthuthukisiwe:Okuphumayo kwesidlulisi esijwayelekile kusiza ukuhlanganiswa okungenamthungo nezinhlelo zokulawula ezifana nesilawuli se-programmable logic (PLC) kanye nohlelo lokulawula olusabalalisiwe (DCS). Ukuxhumana kwedijithali kunika amandla ukuqapha kwedatha yesikhathi sangempela esikude kanye nokulungiswa kwepharamitha, kunciphisa isidingo sokufinyelela ngokomzimba ezindaweni eziyingozi noma okunzima ukuzifinyelela. Ukulungiswa kabusha kwenkundla ngokusebenzisa isixhumi esibonakalayo sedijithali kwenziwa lula futhi kunciphisa isikhathi sokuphumula uma siqhathaniswa nokusebenza mathupha.
Shanghai Wangyuanibilokhu ibambe iqhaza ekukhiqizeni nasekusebenzeleni izinsimbi zokulinganisa iminyaka engaphezu kwengama-20. Ulwazi lwethu olubanzi lobungcweti nolwazi lwasensimini kusivumela ukuthi sikunikeze izixazululo zokulawula izinga lokushisa ezihlangabezana ncamashi nezidingo zakho. Uma kukhona imibuzo nezimfuno mayelana nenzwa yokushisa ne-transmitter, sicela ungangabazi ukusithinta.
