Momwe mungasiyanitsire chitsanzo cha thermocouple

Ma thermocouples omwe amagwiritsidwa ntchito nthawi zambiri amatha kugawidwa m'magulu awiri: ma thermocouples okhazikika ndi osakhazikika. Thermocouple yotchedwa standard thermocouple imatanthawuza thermocouple yomwe mphamvu yake ya thermoelectric ndi kutentha zimayikidwa mu mulingo wadziko, zomwe zimalola zolakwika, ndipo zimakhala ndi tebulo lolozera losasinthika. Ili ndi mawonekedwe ofananirako osankhidwa. Ma thermocouples osakhazikika sali abwino ngati ma thermocouples okhazikika malinga ndi kuchuluka kwa ntchito kapena kuchuluka kwake. Nthawi zambiri, palibe tebulo lolozera, ndipo amagwiritsidwa ntchito poyeza nthawi zina zapadera.

Ma thermocouples asanu ndi awiri okhazikika, S, B, E, K, R, J, ndi T, ndi ma thermocouples amapangidwe osasinthika ku China.

Nambala zolozera za thermocouples makamaka S, R, B, N, K, E, J, T ndi zina zotero. Pakalipano, S, R, B ndi amtengo wapatali azitsulo zamtengo wapatali, ndipo N, K, E, J, T ndi azitsulo zotsika mtengo za thermocouple.

Zotsatirazi ndi kufotokozera kwa chiwerengero cha thermocouple index
S platinamu rhodium 10 platinamu yoyera
R platinamu rhodium 13 pulatinamu koyera
B platinamu rhodium 30 platinamu rhodium 6
K Nickel Chromium Nickel Silicon
Nickel yamkuwa yamkuwa weniweni
J chitsulo cha nickel yamkuwa
N Ni-Cr-Si Ni-Si
E nickel-chromium mkuwa-nickel
(S-mtundu wa thermocouple) platinamu rhodium 10-platinamu thermocouple
Platinamu rhodium 10-platinamu thermocouple (S-mtundu wa thermocouple) ndichitsulo chamtengo wapatali chachitsulo. Kukula kwa waya wa awiriwa kumatchulidwa kuti 0.5mm, ndipo cholakwika chololedwa ndi -0.015mm. Mankhwala omwe amadziwika kuti electrode (SP) ndi platinamu-rhodium alloy yokhala ndi 10% rhodium, 90% ya platinamu, ndi platinamu yoyera ya ma elekitirodi olakwika (SN). Amadziwika kuti platinamu imodzi ya rhodium thermocouple. Kutentha kwakanthawi kochepa kwa thermocouple iyi ndi 1300â „ƒ, ndipo kutentha kwakanthawi kochepa ndi 1600â„ ƒ.
