Ukulinganisa ubushushu yinto ebalulekileyo kulawulo lwenkqubo kwiintlobo ngeentlobo zamashishini afana nokuvelisa iikhemikhali, ioyile negesi, amayeza, kunye nemveliso yokutya. Isenzi sobushushu sisixhobo esibalulekileyo esilinganisa ngokuthe ngqo amandla obushushu kwaye siguqulele intshukumo yobushushu kwimiqondiso yombane ukuze kufezekiswe ukubekwa esweni okuqhubekayo kunye nokuqokelelwa kwedatha malunga nokuba inkqubo iyasebenza ngaphakathi komlinganiselo wobushushu ochaziweyo. Njengoko kukhankanyiwe kwiNgaba singayitshintsha i-RTD nge-Thermocouple?, izinto eziqhelekileyo zokuva ubushushu ziquka i-RTD kunye ne-TR, ezibalaseleyo kubungakanani obahlukeneyo kunye nesignali ye-ohm/mV ephumayo ngokwahlukeneyo.
Nangona isenzi sobushushu sisebenze ixesha elide njengesixhobo esisisiseko sokubamba idatha yobushushu ngokwayo, sinokudityaniswa neenkqubo zokudlulisa idatha kwizicelo zolawulo lwenkqubo. Isenzi sobushushu sisixhobo esiphakathi esiqhagamshela kwi-RTD okanye isenzi se-thermocouple, sikhulise kwaye silungise isignali yesenzi kwisignali yombane eqhelekileyo, size siphume siye kwi-elektroniki efumanayo. Iisignali ezilungiselelwe ukusetyenziswa yinkqubo yolawulo lwangasemva njenge-PLC okanye i-DCS zihlala ziyi-analog 4-20mA kunye nonxibelelwano lwedijithali lweHart okanye lweModbus.
Iingenelo zokusebenzisa i-transmitter yobushushu
Nangona izinzwa zobushushu zihlala zibalulekile ekufumaneni idatha, izithumeli ziphucula ukusetyenziswa kwazo ngokuphucula okuningana:
Ukuqina kwesignali:Isignali yevolthi encinci kwisekethe eveliswa sisinzwa sobushushu sodwa ibuthathaka kwaye ichaphazeleka yingxolo yombane kunye nokuphazamiseka kunye nokuwohloka kwesignali kumgama omde. Xa kuthelekiswa, isignali ye-4-20mA elawulwa sisithumeli inamandla ngakumbi kwaye yenza kube lula ukumelana nokuphazamiseka kwe-electromagnetic. Ukulungelelanisa umgca kunye nokuhlawula imveliso yesinzwa eluhlaza kwenza ukuhanjiswa kwedatha kwisixhobo solawulo kuchaneke ngakumbi kwaye kuthembeke.
Ukuhambelana kunye nokulula:Imodyuli yokudlulisa ubushushu iyahambelana ne-RTD kunye nee-thermocouple sensors. Ukusetyenziswa kwezinto ezininzi zokuva nakho kuyamkeleka. Ukuguquguquka kwenza ukuba i-transmitter isetyenziswe ngokubanzi kuzo zonke iintlobo zokulinganisa ubushushu ngeemfuno ezahlukeneyo zobungakanani be-span kunye ne-sensor. Isalathisi sendawo singabekwa kwibhokisi yesiphelo enika ukufundwa okulula kwendawo kunye noqwalaselo.
Ukuphuculwa kokuhlanganiswa kwenkqubo:Imveliso yokudlulisela esemgangathweni inceda ukuhlanganiswa okungenamthungo neenkqubo zolawulo ezifana ne-programmable logic controller (PLC) kunye ne-distributed control system (DCS). Unxibelelwano lwedijithali luvumela ukujonga idatha ngexesha langempela kunye nokulungiswa kweeparameter, kunciphisa imfuneko yokufikelela ngokwasemzimbeni kwiindawo ezinobungozi okanye ezingenakufikeleleka. Ukulungiswa kwakhona kwentsimi nge-interface yedijithali kwenziwa lula kwaye kunciphisa ixesha lokungasebenzi xa kuthelekiswa nokusebenza ngesandla.
