Njira yopangira wayathermocouplendi motere:
Thermocouples nthawi zambiri amagawidwa kukhala zabwino ndi zoipa. Pamene mawaya, muyenera kulumikiza mbali imodzi ya thermocouple ndi mapeto ena. Matheminali a bokosi lolumikizira amalembedwa ndi zilembo zabwino komanso zoyipa. Nthawi zambiri, malo otchedwa "+" ndi mtengo wabwino, ndipo malo otchedwa "-" ndi mtengo wotsutsa.
Mukalumikiza mawaya, lumikizani ma elekitirodi abwino kumalo otentha a thermocouple ndi ma elekitirodi opanda pake kugawo lozizira la thermocouple. Ma thermocouples ena amafunika kulumikizidwa ndi mawaya amalipiro. Mitengo yabwino ndi yoipa ya mawaya amalipiro ayenera kufanana ndi mitengo yabwino ndi yoipa ya thermocouple. Panthawi imodzimodziyo, kugwirizana pakati pa malo otentha a thermocouple ndi waya wamalipiro ayenera kutsekedwa ndi zipangizo zotetezera.
Kuphatikiza apo, chizindikiro chotulutsa cha thermocouple ndi chocheperako, ndipo chimayenera kulumikizidwa ndi chida choyezera kuti chiwerenge deta. Zida zoyezera nthawi zambiri zimakhala ndi zowonetsera kutentha, zida zoyendera kutentha kwa matchanelo ambiri, ndi zina zotero. Chizindikiro chotuluka cha thermocouple chimayenera kulumikizidwa kumapeto kwa chida choyezera, kenako kuyeza ndi kuwonetsedwa.
Tiyenera kuzindikira kuti njira yopangira ma thermocouples imatha kusiyanasiyana malinga ndi mitundu yosiyanasiyana komanso mawonekedwe. Chifukwa chake, pamagwiritsidwe enieni, ma waya amayenera kuchitidwa molingana ndi mtundu wa thermocouple komanso zofunikira zama waya. Panthawi imodzimodziyo, pofuna kuonetsetsa chitetezo, m'pofunikanso kumvetsera kulondola ndi kudalirika kwa waya kuti mupewe ngozi.
