Yog ib tug kub rhiab caij, thiab yog ib tug thawj ntsuas, thermocouple ntsuas kub ncaj qha. Tsim ntawm 2 txawv neeg xyuas pib ntaub ntawv muaj li ntawm kaw-voj, vim ntaub ntawv sib txawv, sib txawv electron densities tsim electron diffusion, ruaj khov equilibrium yog tsim lub EMF. Thaum lub gradient ntawm kub, tam sim no nyob rau hauv lub Circuit Court, thermoelectric, ntau dua qhov lub kub sib txawv, ntau dua qhov lub currents muaj. Lub ntsuas thermoelectric kub nqi ces koj yuav paub. Thermocouple yog ib qho zog converter uas yuav hloov thermal zog rau hauv hluav taws xob lub zog.
Thermocouple kev zoo: ntau yam ntawm thermocouple thiab kev kawm ntawv piv rau ruaj khov siab ntsuas cov neeg, thermocouple ncaj kev sib cuag nrog tus kwv raug ntsuas, tsis nyob rau hauv tus ntawm medium tshav kub sai teb lub sij hawm, thermocouples kub hloov lo lus teb saj zawg zog xab ntau, tas mus li kub ntsuas ntawm thermoelectric ob peb los ntawm -40 ~ + 1600 c yuav ua tau; thermocouple zog, thiab zoo txhua yam muaj zog. Siv lub neej ntev kiag li lawm.
