Lus piav qhia luv luv:

Hom B thermocouple hlau yog ib hom kub sensor uas yog ib feem ntawm tsev neeg thermocouple, paub txog nws qhov kub thiab txias qhov tseeb. Nws yog tsim los ntawm ob qhov sib txawv hlau hlau txuas ua ke ntawm ib kawg, feem ntau yog ua los ntawm platinum-rhodium alloys. Nyob rau hauv cov ntaub ntawv ntawm hom B thermocouples, ib tug hlau yog tsim los ntawm 70% platinum thiab 30% rhodium (Pt70Rh30), thaum lwm yam hlau yog ua los ntawm 94% platinum thiab 6% rhodium (Pt94Rh6).

Hom B thermocouples yog tsim los ntsuas qhov kub thiab txias, xws li 0 ° C txog 1820 ° C (32 ° F txog 3308 ° F). Lawv feem ntau yog siv rau hauv cov ntawv thov xws li cov chaw tsim khoom siv hluav taws xob, qhov cub, thiab kev sim ntsuas kub kub. Vim yog kev sib xyaw ua ke ntawm cov ntaub ntawv siv, Hom B thermocouples muaj kev ruaj ntseg zoo thiab raug, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias.

Cov thermocouples no nyiam nyob rau hauv cov xwm txheej uas yuav tsum tau muaj qhov tseeb heev, txawm tias lawv raug nqi ntau dua li lwm hom thermocouples. Lawv qhov tseeb thiab ruaj khov ua rau lawv tsim nyog rau kev thov hauv kev lag luam xws li aerospace, automotive, thiab metallurgy.
