Nā kūlana ana wela Thermocouple

He ʻano mea ʻike wela, he ʻano mea hana, thermocouple ana wela pololei.Hoʻokumu ʻia i ʻelua mau mea haku mele o ka conductor i pani ʻia, no ka mea, ʻokoʻa nā mea, ʻokoʻa electron diffusion o electron density, hoʻokumu ʻia ka equilibrium paʻa ma hope o ka hiki uila.Aia ka gradient mahana ma nā ʻaoʻao ʻelua, ʻo ia ka loop, e hana i nā emfs thermoelectric, ʻoi aku ka nui o ka ʻokoʻa wela, ʻoi aku ka nui o ka manawa.E ʻike i ka mahana ma hope o ke ana ʻana o ka thermoelectric emfs.ʻO ka Thermocouple, he ʻano mea hoʻololi ikehu, hiki ke hoʻololi i ka wela i ka uila.

Nā mea maikaʻi ʻenehana Thermocouple: ākea ke ana ʻana o ka wela thermocouple a hoʻohālikelike i ka hana paʻa;ʻO ka pololei o ke ana kiʻekiʻe, pili pololei ka thermocouple me ka mea i ana ʻia, ʻaʻole pili i ka mea waena;He wikiwiki ka manawa pane wela, hiki ke maʻalahi ka pane thermocouple i nā loli wela;Ke ana ākea ākea, thermocouple mai 40 ~ + 1600 ℃ hiki ke hoʻomau i ke ana wela;Paʻa ka hana Thermocouple, ikaika ikaika.Hoʻohana lōʻihi ke ola, mea hana no ka ʻaina awakea.

Pono e hui ʻia nā kāne Galvanic i ʻelua ʻano ʻano like ʻole akā kūpono i kekahi mau koi o ka conductor a i ʻole nā ​​mea semiconductor e lilo i loop.Pono ka ʻokoʻa o ka wela ma waena o ka ʻaoʻao a me ke kuhikuhi.

ʻO ka mea alakaʻi ʻike ʻokoʻa ʻelua a i ʻole ka huila semiconductor, ʻo A a me B ka puka pani.I ka wā e kū ai ka mea hoʻokele A a me B i ʻelua mau ʻokoʻa wela ma waena o 1 a me 2, ma waena o ka ikaika electromotive, no laila ʻo ia ka nui o A i ke kaapuni, ʻo kēia ʻano mea i kapa ʻia ka hopena thermoelectric.Ke hoʻohana nei ka Thermocouple i kēia hopena e hana.
