E-China Osayizi Abahlukahlukene I-Chromel Alumel Intambo Engenalutho Yohlobo lwe-K Ukukhiqizwa Kwenzwa Yezinga lokushisa kanye Nefekthri

Osayizi Abahlukahlukene I-Chromel Alumel Bare Wire Yohlobo lwe-K Inzwa Yezinga lokushisa Isithombe Esifakiwe

Osayizi Abahlukahlukene I-Chromel Alumel Bare Wire Yenzwa Yokushisa Yohlobo lwe-K

Incazelo emfushane:

I-Thermocouple inzwa esetshenziselwa ukukala izinga lokushisa. Ama-thermocouples aqukethe imilenze yocingo emibili eyenziwe ngezinsimbi ezahlukene. Imilenze yezintambo ihlanganiswe ndawonye ekugcineni, yenza ukuhlangana. Lokhu kuhlangana kulapho izinga lokushisa likalwa khona. Lapho i-junction ihlangabezana nokushintsha kwezinga lokushisa, i-voltage iyakhiwa. I-voltage ingase ihunyushwe kusetshenziswa amathebula ereferensi e-thermocouple ukuze kubalwe izinga lokushisa.
Intambo ye-thermocouple ye-NiCr-NiAl (Uhlobo K) ithola ukusetshenziswa okubanzi kakhulu kuyo yonke i-basemetal thermocouple, ezingeni lokushisa elingaphezu kuka-500 °C.

Osayizi Abahlukahlukene I-Chromel Alumel Bare Wire Yenzwa Yokushisa Yohlobo lwe-K

UHLOBO K (CHROMEL vs ALUMEL ) lusetshenziswa ku-oxidizing, inert noma emkhathini wokunciphisa owomile. Ukuchayeka ku-vacuum kunomkhawulo wesikhathi esifushane. Kumele ivikelwe emikhathini enesulfure kanye ne-oxidizing kancane. Ithembekile futhi inembile emazingeni okushisa aphezulu.
