Hom B B Thermocouple xaim yog ib hom ntsuas kub uas yog ib feem ntawm tsev neeg thermochopuple, paub txog nws qhov kev kub siab thiab ruaj khov. Nws yog tsim ntawm ob tus hlau sib txawv koom ua ke ntawm ib qho kawg, feem ntau ua los ntawm platinum-rhodium alloys. Nyob rau hauv cov ntaub ntawv ntawm hom b thermouples, ib tus xaim xaim thiab 30% rho tawm (PTİN0RH30), thaum lub thawv hlau yog ua los ntawm 94% Platinum thiab 6% Rhodium (PT94RH6). Hom b th thermouples yog tsim los ntsuas kev kub siab, xws li 0 ° C txog 1820 ° C (32 ° F txog 3308 ° F). Lawv feem ntau siv nyob rau hauv cov ntawv thov xws li kev muaj cua sov, kilns, thiab ntsuas kub kub-ntsuas kub. Vim tias qhov kev sib xyaw ua ke ntawm cov ntaub ntawv siv, hom b th thermorochoon muaj kev ruaj khov zoo heev thiab qhov tseeb, tshwj xeeb yog thaum muaj kub. Cov thermocouples tau nyiam nyob rau cov xwm txheej uas yuav tsum muaj qhov tseeb heev, txawm tias lawv muaj nqi ntau dua li lwm hom thermocoup. Lawv qhov tseeb thiab ruaj khov ua rau lawv haum rau kev thov kev lag luam hauv kev lag luam xws li aerospace, thiab metallurgy.
