Njengoba sonke sazi, umsebenzi oyinhloko we-thermocouples ukulinganisa nokulawula izinga lokushisa. Zisetshenziswa kakhulu ezimbonini ezifana ne-petrochemical, imithi kanye nokukhiqiza. Ezinqubweni zezimboni, ukuqapha okunembile kwezinga lokushisa kuhlobene eduze nokulawulwa kwekhwalithi yomkhiqizo kanye nokuthuthukiswa kokusebenza kahle kwenqubo. Ngakho-ke, i-platinum-rhodium thermocouple wire iyisinqumo esithembekile nesinembile phakathi kwezinhlobo eziningi zemikhiqizo.
Kodwa yinii-platinum-rhodium thermocouple wire? Ngokusobala, iyi-thermocouple eyakhiwe ngezinsimbi ezimbili eziyigugu, i-platinum ne-rhodium, eklanyelwe ngokukhethekile ukumelana nezinga lokushisa eliphezulu futhi inikeze isilinganiso esinembile sokushisa ngaphansi kwezimo ezimbi kakhulu. Zombili izinsimbi zikhethwa ngokucophelela ngenxa yamaphuzu azo aphezulu ancibilikayo, ukumelana nokugqwala kanye nezinga lokushisa elibanzi. Izinhlobo ezivame kakhulu ze-platinum-rhodium thermocouple wire esizibonayo uhlobo lwe-S (i-platinum-10% i-rhodium/platinum) kanye nohlobo lwe-R (i-platinum-13% ye-rhodium/platinum) thermocouples.
I-Platinum-rhodium thermocouple wire inezici ezimbalwa ezibalulekile. Okokuqala, i-platinum-rhodium thermocouple wire ingakwazi ukumelana namazinga okushisa afika ku-1600°C (2912°F), iyenze ifanelekele ukusetshenziswa kwezinga lokushisa eliphezulu njengokucubungula ukushisa, ukugadwa kwesithando somlilo kanye nokukhiqizwa kwe-aerospace. Okwesibili, inhlanganisela ye-platinum ne-rhodium ocingweni lwe-thermocouple iqinisekisa ukuzinza okuhle kakhulu nokuphindaphinda kokulinganisa izinga lokushisa, ngisho nangaphansi kwezimo zokusebenza ezinzima. Ngaphezu kwalokho, i-platinum-rhodium thermocouple wire nayo inokumelana nokugqwala okuqinile, kanye nesikhathi sokuphendula esisheshayo, futhi ucingo lungafinyelela isilinganiso sokushisa esisheshayo nesinembile, esibalulekile ezinqubweni zemboni ezinamandla.
I-Platinum-rhodium thermocouple wire isetshenziswa kakhulu emikhakheni yezimboni enezidingo eziphakeme kakhulu zokulinganisa nokulawula izinga lokushisa eliphezulu. Isibonelo, embonini yokwelapha ukushisa, i-platinamu-rhodium thermocouple wire isetshenziselwa ukuqapha nokulawula izinga lokushisa kwezithando, amahhavini kanye nezinqubo zokushisa ukushisa ukuze kuqinisekiswe ukuthi izinto ezibonakalayo ezidingekayo zifinyelelwa. Ngaphezu kwalokho, imboni ye-aerospace incike ocingweni lwe-platinum-rhodium ukuze kuqashwe izinga lokushisa okunembile ngesikhathi sokwenziwa kwezingxenye zezindiza, izingxenye zenjini nezinye izinto ezibalulekile ze-aerospace. Imboni yokukhiqiza ingilazi kanye ne-ceramic iyisebenzisela ukuqapha izinga lokushisa leziko kanye neziko elisetshenziswa ekukhiqizeni i-glassware, i-ceramics kanye nezinto eziphikisayo.
Kafushane,i-platinum-rhodium thermocouple wireiyithuluzi elibalulekile lokulinganisa izinga lokushisa nokulawula okunembile emkhakheni wezimboni ezishisa kakhulu. Ukusebenza kwayo okuhle kakhulu, izinga lokushisa elibanzi nokuthembeka kuyenza ibe yinketho yokuqala ezimbonini ezinezidingo eziphakeme kakhulu zokunemba nokuzinza. Kungakhathaliseki ukuthi uhileleke ekwelapheni ukushisa, ukukhiqizwa kwe-aerospace, ukucubungula kwe-petrochemical, noma ezinye izimboni ezidinga ukukalwa kwezinga lokushisa eliphezulu, i-platinum-rhodium thermocouple wire inikeza ukunemba nokuqina okudingekayo ukuze kuqinisekiswe ukusebenza kwenqubo okuphelele kanye nekhwalithi yomkhiqizo.
