Thermocouples yog siv rau hauv cov txheej txheem kom paub qhov kub thiab txias thiab txuas nrog pyrometers rau kev qhia thiab tswj. Thermocouple thiab pyrometer yog hluav taws xob ua los ntawm thermocouple extension cables / thermocouple compensating cables. Cov conductors siv rau cov thermocouple cables yuav tsum muaj cov khoom zoo sib xws thermo-hluav taws xob (emf) raws li cov thermocouple siv los ntsuas qhov kub. Peb cov nroj tsuag tsuas yog tsim hom KX, NX, EX, JX, NC, TX, SC / RC, KCA, KCB them nyiaj xaim rau thermocouple, thiab lawv tau siv rau hauv cov ntsuas kub thiab cov cables. Peb cov khoom siv them nyiaj thermocouple yog tag nrho ua raws li GB / T 4990-2010 'Alloy wires ntawm extension thiab them nyiaj cables rau thermocouples' (Suav National Standard), thiab kuj IEC584-3 'Thermocouple part 3-compensating wire' (International standard). Tus sawv cev ntawm lub comp. xaim: thermocouple code + C / X , xws li SC, KX X: luv rau kev txuas ntxiv, txhais tau hais tias cov nyiaj them nyiaj hlau cov hlau yog tib yam li cov hlau alloy ntawm lub thermocouple C: luv rau cov nyiaj them, txhais tau hais tias cov nyiaj them nyiaj hlau alloy muaj qhov zoo sib xws. cov cim nrog lub thermocouple alloy nyob rau hauv ib tug tej yam kub ntau yam.
