Nga take mo te tono thermocouple kore e tika

E ai ki tete whakamahautau taupū B, S, K, E me etahi atu pāmahana te whakamahau e hāngai ana ki te uara millivolt (MV), i te pāmahana kotahi, ko te uara millivolt (MV) B te tau taupū i hangaia ko te iti rawa , ko te tau taupū S te mea iti rawa, K taupū he nui ake te tau, ko te tau taupū E te mea nui rawa atu, whai i tenei kaupapa ki te whakawa.

Ko nga te whakamahaus e tohuhia ana e te tātaritanga me te manatoko kaore e tika ki te whakamahi. Ko tenei ahuatanga kaore i te mohiotia, kaore ano kia whakaohohia te aro o te tangata. Ko te ahuatanga kore e tika ana ki te tono i te te whakamahau i puta ai te manatokotanga ko te nuinga o te awe o te inhomogeneity o te waea te whakamahau, te hapa shunt o te te whakamahau Armoured me te whakamahi hee o te te whakamahau. Ko te kaiwhakatika whatunga ako hiko e whakamarama ana i te mea ngaro i roto i tenei tuhinga.

Te awe o te inhomogeneity o te waea te whakamahau â‘ Ko te rauemi ote whakamahauhe taurite. Ina tirohia te te whakamahau i roto i te ruuma ine, kia rite ki nga whakaritenga o nga ture, ko te hohonutanga o te whakauru ki roto i te oumu whakaū te whakamahau he 300mm. Na reira, ko te hua whakaahuru o ia te whakamahau ka taea anake te whakaatu, te nuinga ranei o te whakaatu i te waea takirua 300nm te roa mai i te pito inenga. Te whanonga thermoelectric. Engari, ka roa te roa o te te whakamahau, ko te nuinga o nga waea kei roto i te waahi wera teitei i te wa e whakamahia ana. Mēnā he taurite te waea te whakamahau, ā, kei roto i te wāhi me te rōnaki pāmahana, kātahi ka puta te kaha thermoelectromotive tetahi wahi. Ko tenei kaha hiko e kiia ana ko te kaha piripono, a ko te hapa i puta mai i te pumanawa parasitic ka kiia ko te hapa homogeneous.

Te inhomogeneity ote whakamahauwaea i muri i te whakamahinga. Mo te mea hou i hangate whakamahau, ahakoa ka tutuki nga mahi rerekee ki nga whakaritenga, ko te tukatuka tukurua me te piko ka puta te te whakamahau ki te whakaputa i te distortion tukatuka, ka ngaro tona rite. Ano, ka ngaro te riterite o te te whakamahau ka whakamahia mo te wa roa i raro i te wera nui. Ko te paheketanga o te kaha hiko hiko i puta ai te huringa. Mena kei te rohe tetahi wahanga o te paheketanga ki tetahi waahi me te rōnaki pāmahana, ka puta mai he pumanawa hiko parataiao e whakakikoruatia ana ki runga i te katoa o te kaha thermoelectromotive ka whakaatu he hapa ine.
