Ukulinganisa izinga lokushisa kuyisici esibalulekile sokulawula inqubo kuzo zonke izimboni ezibanzi ezifana nokukhiqiza amakhemikhali, uwoyela negesi, imithi, kanye nokukhiqizwa kokudla. Inzwa yokushisa iyithuluzi elibalulekile elilinganisa ngqo amandla okushisa futhi lihumushe ukunyakaza kwezinga lokushisa libe amasignali kagesi ukuze kufezwe ukuqapha okuqhubekayo kanye nokuqoqwa kwedatha yokuthi inqubo iyasebenza yini ngaphakathi kobubanzi bokushisa obuchaziwe. Njengoba kushiwo kuSingakwazi yini ukufaka i-RTD esikhundleni se-Thermocouple?, izakhi ezivamile zokuzwa izinga lokushisa zifaka i-RTD kanye ne-TR, ezisebenza kahle kakhulu ekulinganiseni okuhlukile kanye nesignali ye-ohm/mV ephumayo ngokwahlukana.
Nakuba inzwa yokushisa ibilokhu isebenza njengedivayisi eyisisekelo yokuthwebula idatha yokushisa izimele, ingahlanganiswa nezinhlelo zokudlulisa kuzinhlelo zokusebenza zokulawula izinqubo. I-transmitter yokushisa iyidivayisi ephakathi exhuma ku-RTD noma inzwa ye-thermocouple, ikhulisa futhi ilungise isignali yenzwa kusignali kagesi ejwayelekile, bese iphuma iye kuma-elekthronikhi atholayo. Izimpawu ezilungiselelwe ezifundwa ukusetshenziswa uhlelo lokulawula olungemuva njenge-PLC noma i-DCS ngokuvamile ziyi-analog 4-20mA kanye nokuxhumana kwedijithali kwe-Hart noma i-Modbus.
Izinzuzo zokusebenzisa i-temperature transmitter
Nakuba izinzwa zokushisa zisalokhu zibalulekile ekutholeni idatha, ama-transmitter athuthukisa ukusebenza kwawo ngentuthuko eziningana:
Ukuqina kwesignali okuthuthukisiwe:Isignali ye-voltage encane esesekethe ekhiqizwa yinzwa yokushisa yodwa ibuthakathaka futhi isengozini yomsindo kagesi kanye nokuphazamiseka kanye nokuwohloka kwesignali ebangeni elide. Uma kuqhathaniswa, isignali engu-4-20mA elawulwa yi-transmitter iqine kakhulu futhi yenza kube lula ukumelana nokuphazamiseka kwe-electromagnetic. Ukuhlelwa komugqa kanye nesinxephezelo sokukhishwa kwenzwa eluhlaza kwenza ukudluliselwa kwedatha kudivayisi yokulawula kube okunembe kakhulu futhi okuthembekile.
Ukuhambisana kanye nokulula:Imojula yokudlulisa izinga lokushisa iyahambisana nezinzwa ze-RTD kanye ne-thermocouple. Ukusetshenziswa kwezinto eziningi zokuzwa nakho kungamukeleka. Ukuguquguquka kwenza i-transmitter isetshenziswe kabanzi kuzo zonke izinhlobo zokulinganisa izinga lokushisa ngezidingo ezahlukene zesikhathi kanye nobuningi bezinzwa. Isikhombisi sendawo singabekwa ebhokisini lesiphelo elinikeza ukufundwa kwendawo okulula nokulungiselelwa.
Ukuhlanganiswa kwesistimu okuthuthukisiwe:Ukukhishwa kokudlulisela okujwayelekile kusiza ukuhlanganiswa okungenamthungo nezinhlelo zokulawula ezifana ne-programmable logic controller (PLC) kanye ne-distributed control system (DCS). Ukuxhumana kwedijithali kwenza kube lula ukuqapha idatha ngesikhathi sangempela okude kanye nokulungiswa kwamapharamitha, kunciphisa isidingo sokufinyelela ngokomzimba ezindaweni eziyingozi noma okunzima ukuzifinyelela. Ukulungiswa kabusha kwensimu ngokusebenzisa isikhombikubona sedijithali kwenziwa lula futhi kunciphisa isikhathi sokungasebenzi uma kuqhathaniswa nokusebenza ngesandla.
Shanghai WangyuanUbelokhu ekhiqiza futhi ehlinzeka ngezinsiza zokulinganisa iminyaka engaphezu kwengu-20. Ulwazi lwethu oluningi lobuchwepheshe kanye nokuhlangenwe nakho kwethu ensimini kusenza sikwazi ukuhlinzeka ngezixazululo zokulawula izinga lokushisa ezihlangabezana nezidingo zakho. Uma kukhona imibuzo nezidingo mayelana nenzwa yokushisa kanye nomthumeli, sicela ungangabazi ukuxhumana nathi.
