Me pehea te whakatau mehemea he pai, he kino ranei te thermocouple?

2021-10-09

Ko te whakamahinga o te whakaputa ka nui haere te whanui.Thermocoupleskua riro tetahi o nga waahanga rapunga pāmahana e whakamahia nuitia ana i roto i te umanga. Kei a ratou nga ahuatanga o te tika o te inenga teitei, te awhe ine whanui, te hanga ngawari, me te watea te whakamahi. Ka marama, ka tātarihia e matou nga hua ma roto i nga hongere maha, me te whakaatu i te whānuitanga o nga mohiotanga ahumahi ki te nuinga o te hunga netizens.
No reira ka mohio taatau ki te whakatau mena he pai, he kino ranei tete whakamahau?
Ko te maataapono taketake o te ine ine pāmahanate whakamahau ko nga waahanga rereke e rua o nga kaikawe rauemi hei hanga i te katinga kati. Ina he rōnaki pāmahana i ngā pito e rua, ka rere te au i roto i te kapiti. I tenei wa, he kaha hiko-thermoelectromotive i waenganui i nga pito e rua. Koinei te mea e kiia nei ko te paanga Seebeck. E rua nga kaikawe riterite o nga waahanga rerekehauhikohiko, ko te pito me te mahana teitei ake ko te mutunga o te mahi, ko te mutunga me te mahana o raro ko te mutunga koreutu, a ko te mutunga koreutu i te nuinga o te waa ka mahana tonu.
I muri i te whakamahi mo te wa roa, ka ngenge ngate whakamahaus, ka pakaru pea. Ko te tikanga, ko te kounga o ngate whakamahau e pa ana ki te waeate whakamahau (waea) kei roto, engari me pehea te whakatau i te kounga o te waeate whakamahau te raru. Me korero poto tatou.


Tuatahi, kia mohio kei te kore he raruraru ki te ahua o te waeate whakamahau, he pai, he kino ranei, a ka taea anake te whakatau ma te whakamatautau.
Whakanohoia te waeate whakamahau hei whakamatautau ki runga i te ringaringa uku motuhake mo tete whakamahau, ka maka ki roto i te oumu hiko tubular me te konukawata paerewa me tete whakamahau rhodium, ka whakauru i te pito wera ki roto i te nickel whakarewa porous i roto i te oumu hiko tubular. I roto i te rango. Kuhua nga pito matao o ia waea utu ki roto i te ipu i te kore nga nekehanga Celsius ka mau tonu ma te ranunga o te huka me te wai.
Kia mau ki te oumu ngongo hiko i te mahana tino taea o tete whakamahau, kia mau tonu te awhi nei. I tenei wa, whakamahia he potentiometer Wheatstone whai mana hei ine me te tuhi i te rereketanga pea o te thermoelectric i waenga i tete whakamahau me tete whakamahau hei whakamatautau. E ai ki te rereketanga pea o te thermoelectric kua rekoata, tirohia te tepu whakariterite kia kitea te mahana e rite ana. Mena tete whakamahaui raro i nga whakamatautau kaore i te manawanui, ka taea te whakatau kaore he tohu.
