Dab tsi yog qhov sib txawv ntawm thermocouples thiab thermal resistors?

(1) thermocouces ncaj qha ntsuas kub thiab hloov cov teeb liab kub mus rau hauv qhov kub ntawm cov twj ntsuas hluav taws xob (theem nrab seev). Cov tsos ntawm ntau thermocouples feem ntau sib txawv heev vim lawv cov kev xav tau, tab sis lawv cov qauv yooj yim yog ntxig tib yam. Lawv feem ntau yog tsim cov khoom loj xws li cov ntaub ntawv kub, thiab feem ntau yog siv rau cov twj paj nruag, kaw cov twj paj nruag, thiab cov neeg siv hluav taws xob, thiab cov neeg siv hluav taws xob.
2) Tus thermistor yog cov ntsuas siv tau siv tau yooj yim hauv qhov nruab nrab thiab qhov kub tsawg. Thermal kuj ntsuas kub yog raws li tus yam ntxwv uas cov nqi tiv thaiv ntawm cov hlau uas nce nrog ntsuas kub. Nws cov yam ntxwv tseem ceeb yog qhov ntsuas siab yog qhov tseeb thiab ruaj khov ua haujlwm. Qhov ntsuas ntsuas tau yog cov platinum Tus pas ntsuas kub yog qhov siab, thiab nws tsis yog tsuas yog siv dav hauv kev lag luam kub, tab sis kuj tau ua rau hauv ib qho kev ntsuas kub. Tus cua kub feem ntau yog ua los ntawm cov ntaub ntawv hlau ntshiab, nrog platinum thiab tooj liab tau siv feem ntau. Tsis tas li ntawd, cov ntaub ntawv xws li npib tsib xee, manganese, thiab rhodium tau pib siv los tsim cov cua nab. Muaj ntau ntau hom kev hnov ​​ntsuas kub feem ntau siv nyob rau hauv cov thermistors, nrog platinum xaim yog cov nquag siv. Ntxiv rau cov platinum xaim, kuj tseem tooj liab, npib tsib xee, hlau, hlau npib kub thiab lwm yam khoom siv hlau tshuab thickistor siv.

Yog li ob qho no thermocouples thiab thermal tsim nyog tau hu rau kub ntsuas kub hauv ntsuas kub. Txawm hais tias lawv cov haujlwm zoo ib yam, nkawd ob leeg ntsuas ntsuas kub ntawm cov khoom. Dab tsi yog qhov sib txawv ntawm lawv?
