Isitshisi sobushushu bokumelana (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 zokumelana nobushushu ezenziwe ngeplatinum kule mihla. Enye yeenzuzo zokusebenzisa ii-sensor zobushushu ze-Pt100 kukuchaneka kwazo okuphezulu. Ezi sensor zenzelwe ukubonelela ngemilinganiselo 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 ukumelana kwe-sensor ye-Pt100 ibe sisignali eqhelekileyo ye-4-20mA, enokudluliselwa kwiinkqubo zolawulo zokubeka esweni kunye nokulawula inkqubo. Olu sebenzi lwenza ukuba ii-transmitters zobushushu ze-Pt100 zibe zizinto ezibalulekileyo kwiinkqubo zolawulo lwe-industrial automation kunye neenkqubo zolawulo, okuvumela ukuhlanganiswa okungenamthungo nezixhobo kunye neenkqubo ezikhoyo. Xa kuqwalaselwa ukusetyenziswa kwe-transmitter yobushushu ye-RTD, kufuneka kuthathelwe ingqalelo iiparameter ezininzi ezibalulekileyo. Ezi ziquka uqhagamshelo lwenkqubo, ubunzulu bokufakwa, kunye nobubanzi bentonga, okunokuchaphazela kakhulu ukuchaneka kunye nokuthembeka kokulinganiswa kobushushu. Ngaphezu koko, imveliso ikwafumaneka kwiinketho ezichasene nokuqhuma kunye ne-thermowell, ukuqinisekisa ukhuseleko kunye nokuqina kwiindawo zoshishino ezinzima..Iinketho zesignali yemveliso ziquka i-4-20mA, i-RS-485, kunye ne-HART protocol, okwenza izixhobo zihambelane neenkqubo ezahlukeneyo zolawulo lwemizi-mveliso.
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.izidluliseli ze-temperatruekunye ne-Pt100 yesivamvo sento yokubonelela iimfuno ezithile zesiza ngasinye se-indstuial.
