PR1231/PR1232Iplatinam eqhelekileyo-10% iRhodium / iPlatium Thermocouple
Part1 Isishwankathelo
Umgangatho wokuqala kunye nomgangatho wesibini weplatinam-iridium 10-platinum thermocouples ezinokuchaneka okuphezulu okuhle ngokomzimba kunye neempawu zemichiza, ukumelana ne-oxidation efanelekileyo kumaqondo aphezulu okushisa, ukuzinza okulungileyo kunye nokuphindaphinda kwamandla e-thermoelectromotive.Ngoko ke, isetyenziswe njengesixhobo sokulinganisa esisemgangathweni kwi (419.527 ~ 1084.62) °C, iphinda isetyenziswe ukuhambisa ubukhulu beqondo lokushisa kunye nomlinganiselo ochanekileyo wokushisa kwiqondo lokushisa.

Icandelo3Imiyalelo yesicelo
umgangatho weplatinam-iridium 10-platinum thermocouples kufuneka ihambelane netheyibhile yenkqubo yonikezelo kazwelonke,Kufuneka kuphunyezwe iinkqubo zokuqinisekisa kaZwelonke.Ibanga lokuqala eliqhelekileyo iplatinam-iridium 10-platinum thermocouples ingasetyenziselwa ukulinganisa ibakala lesibini,Ⅰ ibakala,Ⅱ ibakala leplatinam-iridium 10-platinum thermocouples kunye Ⅰ isiseko somgangatho we-thermocouples zentsimbi;Iplatinam-iridium yenqanaba lesibini Ithermocouples yeplatinam ingasetyenziswa kuphela ukulinganisa Ⅱ isiseko sesiseko sesinyithi sethermocouples

Icandelo 4 Ugcino nogcino
1. Ixesha lokulinganisa i-thermocouple calibration ngunyaka we-1, kwaye minyaka yonke i-standard thermocouple kufuneka ilinganiswe lisebe le-metrology.
2. Ulungelelwaniso oluyimfuneko lokusuphavayiza kufuneka lwenziwe ngokosetyenziso.
3. Indawo yokusebenza ye-thermocouple eqhelekileyo kufuneka ihlambuluke ukuze igweme ukungcoliswa kwe-standard thermocouple.
4. Umgangatho we-thermocouple kufuneka ubekwe kwimeko engangcolisi kwaye ukhuselwe kuxinzelelo lomatshini.
Icandelo5 Ulumkeleko xa usetyenziswa
1. I-tube ye-insulation ayikwazi ukusetyenziswa kwiqondo lokushisa eliphezulu lokutshisa.I-tube yokuqala yokugquma isetyenziswe emva kokucoca ngokungqongqo kunye nokutshisa ukushisa okuphezulu.
2. I-tube ye-insulation iyayihoxisa i-positive kunye ne-negative, eya kubangela ukuba i-platinum pole ingcolise kwaye ixabiso le-thermoelectric liyancipha.
3. Ngokuzenzekelayo umbhobho wokugquma we-thermocouple oqhelekileyo kunye nocingo oluncinci luya kungcolisa umgangatho we-thermocouple, kwaye ityhubhu yentsimbi ekhuselayo kufuneka isetyenziselwe ukuqinisekiswa kwesiseko sensimbi ye-thermocouple.
4. I-thermocouple esemgangathweni ayikwazi ukufakwa ngokukhawuleza kwisithando sokushisa, okanye ikhutshwe kwisithando somlilo esilawula ukushisa.Ukushisa ngokukhawuleza kunye nokubanda kuya kuchaphazela ukusebenza kwe-thermoelectric
5.Ngaphantsi kweemeko eziqhelekileyo, i-furnace yokuqinisekisa ye-thermocouple yensimbi exabisekileyo kunye nesiseko se-metal thermocouple kufuneka ihluke ngokuthe ngqo;ukuba akunakwenzeka, ityhubhu ye-ceramic ecocekileyo okanye ityhubhu ye-corundum (ububanzi malunga ne-15mm) kufuneka ifakwe kwityhubhu yesithando sokukhusela i-Thermocouples yentsimbi exabisekileyo kunye ne-thermocouples esemgangathweni ukusuka kwisiseko songcoliseko lwe-metal thermocouple.
