Cov tswv yim siv ntawm thermal kuj

Cov ntaub ntawv thermoelectric feem ntau yog platinum thiab tooj liab: platinum muaj qhov raug siab ua haujlwm, haum rau nruab nrab thiab oxidizing xov xwm, muaj kev ruaj ntseg zoo, thiab muaj qee qhov kev tsis sib xws. Qhov siab dua qhov kub, qhov me me ntawm qhov hloov pauv hloov; Copper kuj muaj ib tug linear kev sib raug zoo nrog kub nyob rau hauv lub kub ntsuas qhov ntau, nrog ib tug loj tus naj npawb ntawm kub kab. Nws yog tsim rau cov xov xwm uas tsis yog corrosive, thiab nws nquag oxidation yog tias nws siab tshaj 150. Cov khoom siv feem ntau hauv Suav teb suav nrog R0=10 Ω, R0=100 Ω, thiab R0=1000 Ω , nrog cov lej kawm tiav ntawm Pt10, Pt100, thiab Pt1000, feem; Muaj ob hom tooj liab resistors, R0=50 Ω thiab R0=100 Ω, nrog lawv cov lej faib Cu50 thiab Cu100. Ntawm lawv, Pt100 thiab Cu50 yog cov siv dav tshaj plaws.
