Isikhangeli soBubushushu obuxhathisayo (RTD), eyaziwayo njengokumelana ne-thermal, yinzwa yobushushu esebenza kumgaqo wokulinganisa ukuba ukuxhathisa kombane kwi-sensor chip material kutshintsha kunye nobushushu.Olu phawuyenza i-RTD ibe yinzwa ethembekileyo nechanekileyo yokulinganisa ubushushu kwizicelo ezahlukeneyo zoshishino.Xa idibene kwi-transmitter yeqondo lokushisa, iba sisixhobo esinamandla sokubeka iliso kunye nokulawula ukushisa kwiinkqubo kunyedlala indima ebalulekileyo kwiinkqubo zolawulo lwenkqubo yoshishino.
I-Pt100 yenye yezona zinto zidumileyo zeplatinam ezenziwe ukuxhathisa ubushushu kule mihla.Enye yeenzuzo zokusebenzisa izinzwa zobushushu ze-Pt100 kukuchaneka kwazo okuphezulu.Ezi zivamvo ziyilelwe ukunika imilinganiselo yobushushu echanekileyo.ukubenza bafanelekele iimeko ezibango zemizi-mveliso okanye elebhu.Nokuba ijonga umphunga womoya, ulwelo, okanye iigesi, izinzwa ze-Pt100 zinokuhambisa ufundo oluchanekileyo, ziqinisekisa ukuba iinkqubo zihamba kakuhle nangempumelelo.Pt100abenzi boluvo baziwa nangokuhlala ixesha elide.Ziyilelwe ukuba zimelane neemeko ezirhabaxa zokusingqongileyo, zizenza zilungele ukusetyenziswa kwiindawo zoshishino apho ukuguquka kwamaqondo obushushu kunye nokuvezwa kweekhemikhali okanye ukufuma.eqhelekileyo.Olu lwakhiwo lomeleleyo luqinisekisa ukuba i-Pt100 sensors inokuqhubeka nokubonelela ngemilinganiselo echanekileyo nakwiimeko zokusebenza ezinzima.
Aisidluliseli sobushushuiyakwazi ukuguqula ukuchasana kwe-sensor ye-Pt100 ibe ngumqondiso we-4-20mA oqhelekileyo, onokuthi udluliselwe kwiinkqubo zokulawula ukubeka iliso kunye nokulawula inkqubo.Oku kusebenza kwenza ii-Pt100 zokuhambisa ubushushu zibe yinxalenye ebalulekileyo kwimizi-mveliso ezenzekelayo kunye neenkqubo zokulawula, okwenza udibaniso olungenamthungo kunye nezixhobo ezikhoyo kunye neenkqubo.Xa kuqwalaselwa ukusetyenziswa kwe-RTD yokuhambisa ubushushu, iiparamitha ezininzi ezibalulekileyo kufuneka zithathelwe ingqalelo.Ezi ziquka uxhulumaniso lwenkqubo, ubunzulu bokufaka, kunye nobubanzi bentonga, ezinokuchaphazela kakhulu ukuchaneka nokuthembeka komlinganiselo wobushushu.Ngaphezu koko, imveliso ikwafumaneka kwiinketho zobungqina bokuqhuma kunye ne-thermowell, iqinisekisa ukhuseleko kunye nokuqina kwiindawo ezinzima zoshishino. iinkqubo.
Thina, iShanghai Wangyuan Instruments of Measurement Co., Ltd. lishishini eliphambili laseTshayina elinobuchwepheshe obuphezulu obugqwesa kubuchwephesha bolawulo lwenkqubo yoshishino kunye neemveliso kangangamashumi eminyaka kwaye sibonelela ngomgangatho ophezulu onokwenziwa ngokwezifiso.abathumeli bobushushu bokwenyanikunye ne-Pt100 yesivamvo sento yokubonelela iimfuno ezithile zesiza ngasinye se-indstuial.
