E mōhio ana tātou katoa, ko te mahi matua o ngā thermocouples ko te ine me te whakahaere i te pāmahana. He whānuitia te whakamahinga i roto i ngā ahumahi pēnei i te hinu matū, te rongoā me te hanga. I roto i ngā tukanga ahumahi, he hononga tata te aroturukitanga tika o te pāmahana ki te whakahaere kounga hua me te whakapai ake i te whai huatanga o te tukanga. Nō reira, he whiringa pono, he whiringa tika hoki te waea thermocouple platinum-rhodium i roto i ngā momo hua maha.

Engari he aha te meawaea whakamahana konukawata-rhodiumHe mārama, he thermocouple tēnei i hangaia mai i ngā konganuku utu nui e rua, arā, ko te platinum me te rhodium, he mea hanga motuhake hei tu atu i ngā pāmahana teitei, hei whakarato i te ine pāmahana tika i raro i ngā āhuatanga tino kino. He mea whiriwhiri pai ngā konganuku e rua mō ō rātou ira rewa teitei, te ātete ki te waikura me te whānuitanga o te pāmahana. Ko ngā momo waea thermocouple platinum-rhodium e kitea ana e tātou ko ngā thermocouple momo-S (platinum-10% rhodium/platinum) me te momo-R (platinum-13% rhodium/platinum).

He maha ngā āhuatanga matua o te waea thermocouple platinum-rhodium. Tuatahi, ka taea e te waea thermocouple platinum-rhodium te tu atu ki ngā pāmahana tae atu ki te 1600°C (2912°F), e pai ai mō ngā tono pāmahana teitei pēnei i te tukatuka wera, te aroturuki oumu me te hanga rererangi. Tuarua, ko te whakakotahitanga o te platinum me te rhodium i roto i te waea thermocouple ka whakarite kia tino pumau me te auau o te ine pāmahana, ahakoa i raro i ngā āhuatanga mahi uaua. Hei tāpiri, he kaha te ātete ki te waikura o te waea thermocouple platinum-rhodium, me te wā urupare tere, ā, ka taea e te waea te whakatutuki i te ine pāmahana tere me te tika, he mea nui i roto i ngā tukanga ahumahi hihiri.
