TC (thermocouple) yog ntsuas qhov ntsuas qhov ntsuas cov ntsuas qhov kub thiab txias, ntsuas kub thiab thermoelectric kub qhov teeb meem hauv cov teeb meem ntawm cov khoom siv hluav taws xob (ntsuas thib ob) hloov cov ntsuas ntawm qhov nruab nrab. Ntau hom thermocouple feem ntau yuav tsum txawv heev, tab sis cov qauv yooj yim tseem zoo tib yam, feem ntau los ntawm thermal electrode, insulator tiv thaiv tubes thiab qhov chaw thawv thiab lwm qhov chaw loj, thiab cov yeeb yam pom, feem ntau txhawb siv cov ntaubntawv povthawj siv thiab cov electronic regulator.
Hauv cov txheej txheem tsim tawm, nws yog ib qho tseem ceeb tshaj plaws uas ntsuas thiab tswj tau qhov kub thiab txias. Hauv kev ntsuas ntawm qhov kub thiab txias, cov thermocouples siv dav, nws yog yooj yim hauv cov qauv, yooj yim los tsim, dav ntsuas ntau, siab raug, tsis tshua muaj inertia, thiab cov teeb liab tso zis ntev-kis kis, thiab ntau lwm yam zoo. Tsis tas li ntawd, txij li thaum lub thermocouple yog ib qho ua kom pom tseeb, ntsuas tsis tau siv hluav taws xob sab nraud, nws yooj yim heev rau siv, feem ntau hauv qhov cub, yeeb nkab yog siv raws li kev ntsuas roj lossis qhov kub ntawm cov kua thiab cov khoom nto.
