ʻO ka wehewehe pōkole:

ʻO ka uea thermocouple Type B he ʻano mea ʻike wela i ʻāpana o ka ʻohana thermocouple, i ʻike ʻia no ka pololei o ka wela kiʻekiʻe a me ke kūpaʻa. Ua haku ʻia me ʻelua mau uwea metala ʻokoʻa i hui pū ʻia ma kekahi ʻaoʻao, i hana maʻamau ʻia me nā alloys platinum-rhodium. Ma ka hihia o Type B thermocouples, hoʻokahi uea i haku ʻia me 70% platinum a me 30% rhodium (Pt70Rh30), aʻo kekahi uea i hana ʻia me 94% platinum a me 6% rhodium (Pt94Rh6).

Hoʻolālā ʻia nā thermocouple ʻano B e ana i nā wela kiʻekiʻe, mai ka 0°C a i 1820°C (32°F a 3308°F). Hoʻohana pinepine ʻia lākou i nā noi e like me nā umu ahi, nā kiln, a me nā hoʻokolohua hoʻokolohua wela kiʻekiʻe. Ma muli o ka hui pololei ʻana o nā mea i hoʻohana ʻia, hāʻawi nā thermocouple Type B i ke kūpaʻa maikaʻi loa a me ka pololei, ʻoi aku hoʻi i nā wela kiʻekiʻe.

ʻOi aku ka maikaʻi o kēia mau thermocouple ma nā kūlana e koi ʻia ai ka pololei kiʻekiʻe loa, ʻoiai ʻoi aku ke kumu kūʻai ma mua o nā ʻano thermocouple ʻē aʻe. ʻO kā lākou pololei a me ke kūpaʻa e kūpono iā lākou no ke koi ʻana i nā noi i nā ʻoihana e like me ka aerospace, automotive, a me ka metallurgy.
