Kutheni iPt1000 isetyenziswa kakhulu kwiUkulinganisa ubushushukunye nomahluko wayo kwi-Pt500 kunye ne-Pt100
Intshayelelo
Kushushuumlinganiselousetyenziso, izinzwa zobushushu zidlala indima ebalulekileyo ekumiseleni ngokuchanekileyo ubushushu, nto leyo ebalulekileyo ekubaleni ukudluliselwa kobushushu kunye nokusetyenziswa kwamandla. Phakathi kweentlobo ngeentlobo zezinzwa zobushushu, izinzwa zobushushu ezichasene neplatinum (iiRTD) zisetyenziswa kakhulu ngenxa yokuchaneka kwazo okuphezulu, ukuzinza, kunye nobubanzi bobushushu. IiPt1000, iiPt500, kunye neePt100 ziintlobo eziqhelekileyo zeeRTD zeplatinum, apho iPt1000 iyeyona ikhethwa rhoqo kwiimeko ezininzi zokulinganisa ubushushu. Eli nqaku liza kuphonononga izizathu zokuthandwa kwePt1000 kwaye lixoxe ngomahluko phakathi kwePt1000, iiPt500, kunye neePt100.
Izizathu zokusetyenziswa ngokubanzi kwe-Pt1000 ekulinganiseni ubushushu
Uvakalelo oluphezulu
I-Pt1000 inokumelana okuqhelekileyo kwe-1000 ohms kwi-0 °C, ngelixa i-Pt100 inokumelana okuqhelekileyo kwe-100 ohms kubushushu obufanayo, kwaye i-Pt500 inokumelana okuqhelekileyo kwe-500 ohms kwi-0 °C. Ukumelana okuphezulu kwe-Pt1000 kubangela utshintsho olukhulu kukutshintsha kobushushu ngeyunithi nganye. Umzekelo, kutshintsho oluncinci lobushushu, utshintsho lokumelana kwe-Pt1000 lubaluleke ngakumbi xa kuthelekiswa ne-Pt100 kunye ne-Pt500. Olu luvo luphezulu luvumela ukulinganiswa kobushushu okuchanekileyo, okubaluleke kakhulu kwiumlinganiselo wobushushuapho umahluko omncinci wobushushu unokuba nefuthe elikhulu ekuchanekeni kokubala ubushushu. Kwizicelo ezifana ne-high-precision calorimetry, apho utshintsho lobushushu lwemizuzu kufuneka lufunyanwe ngokuchanekileyo ukuze kubalwe ukudluliselwa kobushushu ngokuchanekileyo, uvakalelo oluphezulu lwe-Pt1000 lubonelela ngenzuzo eyahlukileyo.
Impembelelo Encitshisiweyo Yokumelana Neentambo ZeLead
Kwiisetingi zokulinganisa ubushushu ezisebenzayo, isenzi sobushushu sidla ngokudityaniswa nesixhobo sokulinganisa ngeentambo zentsimbi. Ukumelana kwezi ntambo zentsimbi kunokubangela iimpazamo kwixabiso lokumelana elilinganisiweyo le-RTD kwaye ngaloo ndlela kuchaphazele ukuchaneka kokulinganisa ubushushu. Ekubeni i-Pt1000 inokumelana okuphezulu okuqhelekileyo, impembelelo yokumelana kwentambo yentsimbi yentsimbi kwisilinganiso sokumelana sisonke incinci xa ithelekiswa ne-Pt100 kunye ne-Pt500. Umzekelo, ukuba ukumelana kwentambo yentsimbi yentsimbi yi-ohms ezimbalwa, kuya kubangela impazamo enkulu yepesenti kwisiphatho esilinganisiweyo se-Pt100 (enokumelana okuqhelekileyo kwe-100 ohms) xa kuthelekiswa ne-Pt1000 (enokumelana okuqhelekileyo kwe-1000 ohms). Oku kwenza i-Pt1000 ifaneleke ngakumbi kwizicelo apho ubude bentambo yentsimbi yentsimbi yentsimbi bufuneka khona, njengakwiinkqubo zokudlulisa ubushushu kwimizi-mveliso apho isenzi sobushushu sinokuba kude negumbi lolawulo.
Ukuhambelana ne-Modern Electronics
Izixhobo zokulinganisa ze-elektroniki zanamhlanje zenzelwe ukuphatha uluhlu olubanzi lwezibonakaliso zokufaka. I-Pt1000, enokumelana kwayo okuqhelekileyo kwe-1000 - ohm kwi-0 °C, ihambelana kakuhle nokukwazi kwe-input impedance kunye ne-signal - conditioning kwiinkqubo ezininzi zokulinganisa nokulawula zanamhlanje. Ezi nkqubo zihlala zilungele ukusebenza ngezibonakaliso ezihambelana neempawu zokumelana - ubushushu be-Pt1000. Umzekelo, iimodyuli ezininzi zokulinganisa ubushushu ezisekelwe kwi-microcontroller zilungiselelwe ngokukodwa izinzwa ze-Pt1000, zibonelela nge-interfaces ezilula ukuzisebenzisa kunye nokufundwa kobushushu okuchanekileyo. Oku kuhambelana kwenza kube lula ukuyila kunye nokusetyenziswa kweenkqubo zokulinganisa ubushushu, kunciphisa isidingo seenkqubo ezinzima zokuguqula uphawu kunye nokulinganisa.
Imfuneko yezicelo ezichanekileyo kakhulu
Umlinganiselo wobushushuKwezinye iindawo, ezinje ngophando lwezenzululwazi, ukwenziwa kwamayeza, kunye neenkqubo zoshishino eziphezulu, zifuna ukulinganiswa kobushushu obuchanekileyo kakhulu. I-Pt1000 inokuhlangabezana nezi mfuno ngokuchaneka kwayo okuphezulu kunye nokuzinza. Kwizilingo zesayensi ezinxulumene ne-thermodynamics, ukulinganiswa kobushushu obuchanekileyo kubalulekile ekuqinisekiseni iimodeli zethiyori. Impazamo encinci ekulinganisweni kobushushu inokukhokelela ekuphambukeni okukhulu kwiziphumo zokubala ubushushu. I-Pt1000, ngokusebenza kwayo okugqwesileyo ekuqondeni ubushushu obuchanekileyo, iqinisekisa ukuba idatha yokulinganisa ubushushu efunyenweyo inokuthenjwa kwaye inokuxhasa uphando lwezenzululwazi olunzulu kunye neenkqubo zemveliso yemizi-mveliso esemgangathweni ophezulu.
Umahluko phakathi kwe-Pt1000, i-Pt500, kunye ne-Pt100
Amaxabiso Okuchasana Okuqhelekileyo
Njengoko bekutshiwo ngaphambili, umahluko ocacileyo phakathi kwePt1000, Pt500, kunye nePt100 ngamaxabiso azo okuxhathisa aqhelekileyo kwi-0 °C.

Ukukhetha ukumelana okuqhelekileyo kuxhomekeke kwiimfuno ezithile zeumlinganiselo wobushushuukusetyenziswa, okufana nokuchaneka komlinganiselo okufunekayo, ubude beengcingo zentsimbi, kunye nokuhambelana nenkqubo yokulinganisa ekhoyo.
Uvelwano kunye nokuchaneka
I-Pt1000 ngokubanzi inika uvakalelo oluphezulu phakathi kwezi zintathu, ilandelwe yi-Pt500 kunye ne-Pt100. Uvakalelo lunxulumene notshintsho lokumelana nge-degree Celsius yotshintsho lobushushu. Okukhona ukumelana okuqhelekileyo kuphezulu, kokukhona utshintsho olukhulu lokumelana notshintsho lobushushu oluthile, nto leyo ekhokelela kuvakalelo oluphezulu. Ngokuphathelele ukuchaneka, zonke iintlobo ezintathu ze-platinum RTDs zinokufikelela kuchanekileyo oluphezulu xa zilinganiswe ngokufanelekileyo. Nangona kunjalo, ngenxa yovakalelo oluphezulu, i-Pt1000 inokubonelela ngokulinganisa ubushushu obuchanekileyo ngakumbi kwizicelo apho umahluko omncinci wobushushu kufuneka usonjululwe ngokuchanekileyo. Umzekelo, kuvavanyo lokusebenza kakuhle kwe-heat exchanger, apho umahluko wobushushu phakathi kolwelo lokungena kunye nolwelo oluphumayo unokuba zii-degrees Celsius ezimbalwa kuphela, i-Pt1000 inokulinganisa la mahluko mancinci ngokuchanekileyo kune-Pt100.
Ixabiso
Ngokubanzi, ixabiso lee-sensors ze-Pt1000 liphezulu kakhulu kunele-Pt100 kunye ne-Pt500. Oku kungenxa yokuba inkqubo yokuvelisa ii-sensors ze-Pt1000 ifuna ulawulo oluchanekileyo ngakumbi ukuze kufezekiswe ixabiso eliphezulu lokumelana kunye neempawu zokusebenza eziphezulu ezinxulumene nazo. Ixabiso eliphezulu linokuba yinto ethintelayo kwezinye izicelo ezinobuzaza beendleko. Nangona kunjalo, kwizicelo apho ukulinganisa ubushushu obuchanekileyo kubaluleke kakhulu, njengakwishishini leenqwelo moya zolawulo lobushushu benjini okanye kwizixhobo zonyango eziphezulu kwiinkqubo ezilawulwa bubushushu, iingenelo zokusebenza ze-Pt1000 zihlala zingaphezulu kunexabiso. I-Pt100, kwelinye icala, ixabisa kakhulu kwaye inokufaneleka kwizicelo apho ukuchaneka okufunekayo kungaphantsi kakhulu, njengezicelo ezithile zokujonga ubushushu bemizi-mveliso.
Imizekelo yesicelo
I-Pt1000 isetyenziswa kakhulu kwizicelo apho kufuneka umlinganiselo wobushushu ochanekileyo, njengakwiilabhoratri zophando zovavanyo lwe-calorimetry, kwishishini le-semiconductor lokulawula ubushushu ngexesha lokucubungula i-wafer, nakwiinkqubo ze-HVAC eziphezulu zokulinganisa ukusetyenziswa kwamandla ngokuchanekileyo. I-Pt500 ingasetyenziswa kwezinye izicelo zokuchaneka okuphakathi apho iimfuno zobuntununtunu ziphezulu kunezo ze-Pt100 kodwa zingabi ngqongqo njengeze-Pt1000. I-Pt100, enexabiso layo eliphantsi kwaye isamkelekileyo kwizicelo ezininzi zeenjongo eziqhelekileyo, isetyenziswa kakhulu ekujongeni ubushushu bemizi-mveliso, njengakwi-boiler control, ukuva ubushushu begumbi kwizakhiwo, kunye nokujonga ubushushu benjini yeemoto ngokusisiseko.
Isiphelo
Ukuqukumbela, i-Pt1000 isetyenziswa kakhulu kubushushuumlinganiselongenxa yobuthathaka bayo obuphezulu, impembelelo ephantsi yokumelana nentambo yelead, ukuhambelana ne-elektroniki yanamhlanje, kunye nokukwazi ukuhlangabezana neemfuno zezicelo ezichanekileyo.
