Okokuqala, maqondana nokwakheka kwezinto, ucingo lwe-thermocouple lohlobo lwe-J luqukethe inhlanganisela yensimbi ne-constantan. Insimbi isebenza njengomlenze omuhle, kuyilapho i-constantan (aithusi - i-alloy ye-nickel) isebenza njengomlenze ongemuhle. Ngokuphambene nalokho, ucingo lwe-thermocouple lohlobo lwe-K lwenziwe nge-i-chromel- inhlanganisela ye-alumiyeli. I-Chromel, eyakhiwa kakhulu yi-nickel ne-chromium, ingumlenze omuhle, kanti i-alumiyeli, i-nickel - i-aluminium - i-manganese - i-silicon alloy, ingumlenze omubi. Lo mehluko ezintweni uholela ekuhlukeni kwezici zazo zokusebenza.

Okwesibili, amazinga okushisa abangawalinganisa ayahlukahluka kakhulu.J - uhlobo lwe-thermocouplesngokuvamile ingalinganisa amazinga okushisa kusukela ku-210°C kuya ku-760°C. Zifaneleka kahle ezinhlotsheni ezahlukene zezicelo ezinezidingo zokushisa eziphakathi nendawo. Isibonelo, embonini yokucubungula ukudla, ama-thermocouple ohlobo lwe-J avame ukusetshenziswa kuma-oven okubhaka. Lapho kubhaka isinkwa, izinga lokushisa ngaphakathi kuhhavini livame ukusuka ku-150°C kuya ku-250°C. Izintambo zethu ze-thermocouple zohlobo lwe-J ezisezingeni eliphezulu zingaqapha ngokunembile lawa mazinga okushisa, ziqinisekise ukuthi isinkwa sibhakwa ngokulinganayo futhi sifinyelela ukuthungwa okuphelele. Esinye isicelo sisekukhiqizweni kwemithi, lapho ama-thermocouple ohlobo lwe-J asetshenziswa khona ukukala izinga lokushisa ngesikhathi senqubo yokomisa imithi ethile. Izinga lokushisa kule nqubo livame ukugcinwa ngaphakathi kuka-50°C kuya ku-70°C, futhi imikhiqizo yethu yezintambo ze-thermocouple zohlobo lwe-J inganikeza idatha yokushisa ethembekile, ivikele ikhwalithi yemithi.

Ngakolunye uhlangothi, ama-thermocouple ohlobo lwe-K anobubanzi bokushisa obubanzi, kusukela ku-200°C kuya ku-1350°C. Lokhu kuwenza abaluleke kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu. Embonini yokwenza insimbi,Ama-thermocouple ohlobo lwe-Kzisetshenziselwa ukuqapha izinga lokushisa ngaphakathi kwesithando somlilo. Izinga lokushisa esithandweni somlilo lingafinyelela ku-1200°C noma ngaphezulu. Izintambo zethu ze-thermocouple zohlobo lwe-K zingamelana nokushisa okukhulu kangaka ngenkathi zigcina ukunemba okuphezulu, okuvumela abaqhubi ukuthi balawule ngokunembile inqubo yokuncibilikisa futhi baqinisekise ikhwalithi yensimbi. Emkhakheni wezindiza, ngesikhathi sokuhlolwa kwezingxenye zenjini yejethi, ama-thermocouple ohlobo lwe-K asetshenziselwa ukukala amagesi okushisa aphezulu akhiqizwa ngesikhathi sokusebenza kwenjini. Lawa magesi angafinyelela amazinga okushisa aseduze no-1300°C, kanti imikhiqizo yethu yezintambo ze-thermocouple zohlobo lwe-K inganikeza ukufundwa kwezinga lokushisa okunembile, okubalulekile ekuthuthukisweni nasekuthuthukisweni kwezinjini zejethi.

Ukunemba kungenye isici esibalulekile. Ama-thermocouple ohlobo lwe-K ngokuvamile anikeza ukunemba okungcono ebangeni lokushisa elibanzi uma kuqhathaniswa nama-thermocouple ohlobo lwe-J. Ukuqina kwama-thermocouple ohlobo lwe-K ezindaweni ezinzima nakho kunegalelo ekunembeni kwawo okuphezulu, okwenza kube ukukhetha okuthandwayo kocwaningo lwesayensi kanye nezinqubo zezimboni ezinembile kakhulu.

KwaTankii, imikhiqizo yethu yezintambo ze-thermocouple ze-J kanye ne-K ikhiqizwa ngokulawulwa kwekhwalithi okuqinile. Izintambo zethu ze-thermocouple ze-J ziqinisekisa ukusebenza okuthembekile ngaphakathi kwebanga lazo lokushisa elibekiwe, kuyilapho izintambo zethu ze-thermocouple ze-K zenzelwe ukumelana namazinga okushisa aphezulu ngokunemba okuhle kakhulu nokuzinza. Kungakhathaliseki ukuthi udinga ukukala izinqubo zokuqandisa zezinga lokushisa eliphansi noma ukusabela kwezimboni kwezinga lokushisa eliphezulu, imikhiqizo yethu yezintambo ze-thermocouple ingakunikeza idatha yokushisa enembile nezinzile, ikusize wenze ngcono imisebenzi yakho futhi uqinisekise ikhwalithi yomkhiqizo.
