Kufotokozera Kwachidule:

Waya wa thermocouple wa mtundu wa B ndi mtundu wa sensa yowunikira kutentha yomwe ndi gawo la banja la thermocouple, lodziwika bwino chifukwa cha kulondola kwake kutentha kwambiri komanso kukhazikika kwake. Limapangidwa ndi mawaya awiri achitsulo osiyana omwe amalumikizidwa pamodzi kumapeto amodzi, nthawi zambiri amapangidwa ndi ma alloy a platinum-rhodium. Pankhani ya ma thermocouple a mtundu wa B, waya umodzi umapangidwa ndi 70% platinum ndi 30% rhodium (Pt70Rh30), pomwe waya wina umapangidwa ndi 94% platinum ndi 6% rhodium (Pt94Rh6).

Ma thermocouple a Mtundu B adapangidwa kuti ayesere kutentha kwambiri, kuyambira 0°C mpaka 1820°C (32°F mpaka 3308°F). Amagwiritsidwa ntchito kwambiri m'mafakitale monga uvuni zamafakitale, ma uvuni, ndi zoyeserera za labotale zotentha kwambiri. Chifukwa cha kuphatikiza kolondola kwa zinthu zomwe zimagwiritsidwa ntchito, ma thermocouple a Mtundu B amapereka kukhazikika komanso kulondola kwabwino, makamaka kutentha kwambiri.

Ma thermocouple amenewa amakondedwa kwambiri pakakhala kulondola kwambiri, ngakhale kuti ndi okwera mtengo kwambiri kuposa mitundu ina ya ma thermocouple. Kulondola kwawo komanso kukhazikika kwawo zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'mafakitale monga ndege, magalimoto, ndi zitsulo.
