Okokuqala, mayelana nokubunjwa kwezinto ezibonakalayo, i-J - uhlobo lwe-thermocouple wire iqukethe inhlanganisela ye-iron - constantan. Insimbi isebenza njengomlenze oqondile, kuyilapho i-constantan (aithusi - ingxubevange ye-nickel) isebenza njengomlenze ongemuhle. Ngokuphambene, i-K - uhlobo lwe-thermocouple wire yenziwe nge-i-chromel- inhlanganisela ye-alum. I-Chromel, eyakhiwe kakhulu nge-nickel ne-chromium, iwumlenze oqondile, kanti i-amel, i-nickel - i-aluminium - i-manganese - i-silicon alloy, iwumlenze ongemuhle. Lo mehluko kokubalulekile uholela ekuhlukeni kwezici zabo zokusebenza.

Okwesibili, amazinga okushisa abangawalinganisa ayahluka kakhulu.J - thayipha ama-thermocouplesngokuvamile ingakala amazinga okushisa ukusuka ku -210°C kuya ku-760°C. Zifanele kahle - zilungele izinhlelo zokusebenza ezihlukahlukene ezinezidingo zokushisa ezimaphakathi. Isibonelo, embonini yokucubungula ukudla, ama-thermocouples ohlobo lwe-J avame ukusetshenziswa kumahhavini okubhaka. Uma ubhaka isinkwa, izinga lokushisa ngaphakathi kuhhavini livamise ukusuka ku-150°C kuya ku-250°C. Izintambo zethu zekhwalithi ephezulu engu-J - uhlobo lwe-thermocouple zingakwazi ukuqapha ngokunembile lawa mazinga okushisa, ziqinisekise ukuthi isinkwa sibhakwa ngokulinganayo futhi sifeza ukuthungwa okuphelele. Esinye isicelo sisekwenziweni kwemithi, lapho kusetshenziswa khona ama-thermocouples ohlobo lwe-J ukuze kukale izinga lokushisa ngesikhathi sokumiswa kwemithi ethile. Izinga lokushisa kule nqubo livame ukugcinwa phakathi kuka-50°C kuya ku-70°C, futhi imikhiqizo yethu yocingo lwe-thermocouple yohlobo lwe-J - inganikeza idatha ethembekile yokushisa, ivikele ikhwalithi yemithi.

I-K - uhlobo lwama-thermocouples, ngakolunye uhlangothi, anebanga lokushisa elibanzi, ukusuka ku-200°C kuya ku-1350°C. Lokhu kubenza babaluleke kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu. Embonini yokwenza insimbi,K - thayipha ama-thermocoupleszisetshenziselwa ukuqapha izinga lokushisa ngaphakathi kwesithando somlilo. Amazinga okushisa esithandweni somlilo angafinyelela ku-1200°C noma ngaphezulu. Izintambo zethu zohlobo lwe-K - thermocouple zingamelana nokushisa okukhulu kangako kuyilapho zigcina ukunemba okuphezulu, okuvumela opharetha ukuthi balawule ngokunembile inqubo yokuncibilikisa futhi baqinisekise ikhwalithi yensimbi. Emkhakheni we-aerospace, ngesikhathi sokuhlolwa kwezingxenye zenjini ye-jet, ama-thermocouples ohlobo lwe-K asetshenziswa ukukala amagesi okushisa aphezulu akhiqizwa ngesikhathi sokusebenza kwenjini. Lawa magesi angafinyelela amazinga okushisa asondele ku-1300°C, futhi imikhiqizo yethu yocingo lwe-thermocouple yohlobo lwe-K inganikeza ukufundwa okunembile kwezinga lokushisa, okubalulekile ekuthuthukisweni nasekusebenzeni kahle kwezinjini zejethi.

Ukunemba kungesinye isici esibalulekile. K - uhlobo lwe-thermocouples ngokuvamile lunikeza ukunemba okungcono ngaphezu kwebanga elibanzi lokushisa uma kuqhathaniswa no-J - uhlobo lwe-thermocouples. Ukuzinza kwama-thermocouples ohlobo lwe-K ezindaweni ezinokhahlo nakho kunomthelela ekunembeni kwawo okuphezulu, okuwenza abe yinketho ekhethwayo yocwaningo lwesayensi nezinqubo zezimboni ezinembayo.

E-Tankii, imikhiqizo yethu yocingo lwe-J kanye ne-K thermocouple yenziwa ngokulawulwa kwekhwalithi okuqinile. Izintambo zethu ze-thermocouple zohlobo lwe-J ziqinisekisa ukusebenza okuthembekile ngaphakathi kwebanga lazo lokushisa elishiwo, kuyilapho izintambo zethu zohlobo lwe-K - thermocouple ziklanyelwe ukumelana nezinga lokushisa eliphezulu ngokunemba okuhle kakhulu nokuzinza. Kungakhathaliseki ukuthi udinga ukulinganisa izinqubo zesiqandisi esiphansi - izinga lokushisa eliphansi noma izinga lokushisa eliphezulu lokusabela kwezimboni, imikhiqizo yethu yezintambo ze-thermocouple ingakunikeza idatha yezinga lokushisa elinembile nelizinzile, ikusize ulungiselele imisebenzi yakho futhi uqinisekise ikhwalithi yomkhiqizo.
