I-High Precision Type K Thermocouple Alloy Wire 0.5mm KP KN Wire
Intambo ye-Thermocouple ivumela amazinga okushisa ukuthi akalwe nge-elekthronikhi. Ukwakhiwa kwe-thermocouple okujwayelekile kuhlanganisa ipheya yezinsimbi ezingafani ezihlanganiswe ngogesi endaweni yenzwa futhi zixhunywe kuthuluzi lokulinganisa i-voltage ngakolunye uhlangothi. Uma ukuhlangana okukodwa kushisa kunomunye, amandla ashisayo “e-electromotive” (ngama-millivolts) akhiqizwa acishe alingane nomehluko wamazinga okushisa phakathi kwezindawo ezishisayo nezibandayo.
I-NiCr-NiSi (Uhlobo K)ucingo lwe-thermocoupleithola ukusetshenziswa okubanzi kakhulu kuyo yonke i-basemetal thermocouple, ezingeni lokushisa elingaphezu kuka-500 °C.
Uhlobo Kucingo lwe-thermocoupleinokumelana okuqinile ne-oxidation kunamanye ama-thermocouples ensimbi ayisisekelo. Ine-EMF ephezulu uma iqhathaniswa nePlatinum 67, ukunemba okuhle kakhulu kwezinga lokushisa, ukuzwela nokuzinza, ngezindleko eziphansi. Inconyelwe i-oxidizing noma i-inert atmosphere, kodwa ayikwazi ukusetshenziswa ngokuqondile kulezi zimo ezilandelayo:
(1) Ngenye indlela i-oxidizing nokunciphisa umkhathi.
(2) Umkhathi onamagesi esibabule.
(3) Isikhathi eside ku-vacuum.
(4) Umkhathi ophansi one-oxidizing njenge-hydrogen ne-carbon monoxide emkhathini.
