Uea Hoʻonui Thermocouple
Uea hoʻonui Thermocouple a me uea i hoʻohana ʻia i ke ʻano ana wela e ka thermocouple, aia i ʻelua metala like ʻole i hui pū ʻia ma ka hopena ʻike. Hoʻohana ka uea hoʻonui i nā mea like me ka thermocouple e hoʻolōʻihi mai ka thermocouple a i nā lako ana.
Nā hiʻohiʻona: ʻO ke kūpaʻa thermoelectric maikaʻi loa, nā waiwai mechanical a me nā uila, ke ola hana lōʻihi;
Hoʻolālā maʻalahi, hiki ke maʻalahi, maʻalahi no ka hui;
Paʻa kemika kiʻekiʻe, pale i ka wela, a pale i ka hau o ka lole.
