Compensating xov hlau feem ntau yog ua los ntawm kev hloov cov thermocouples nrog cov xov hlau uas muaj tib lub electron ceev. Kev sib txuas ntawm cov xaim them nyiaj thiab cov thermocouple feem ntau yog qhov tseeb: lub davhlau ya nyob twg zoo ntawm lub thermocouple txuas nrog cov xaim liab ntawm cov xaim them nyiaj, thiab lub davhlau ya nyob twg tsis zoo yog txuas nrog cov xim xim ntxiv. Feem ntau cov xov hlau them nyiaj yog ua los ntawm tooj liab -nickel alloy.
Lub hom phiaj ntawm kev siv cov nyiaj them rov qab:
(1) Txhawm rau txav qhov kawg ntawm cov thermocouple los ntawm qhov siab - qhov kub thiab txias mus rau qhov chaw uas muaj qhov kub thiab txias ambient.
(2) Yuav kom txuag tau ib qho tseem ceeb ntawm cov khoom kim heev thiab tsis tshua muaj hlau siv hauv kev tsim cov thermocouple electrodes.
(3) Txhawm rau txhim kho kev teeb tsa thiab xaim.
(4) Hloov cov thermocouple electrodes nrog tuab txoj kab uas hla compensating xov hlau nrog ntau dua conductivity txo qhov tsis kam ntawm thermocouple Circuit Court, yooj yim ntsuas thiab tsis siv neeg tswj.
