Kufotokozera Kwachidule:

Waya wa mtundu wa B thermocouple ndi mtundu wa sensa ya kutentha yomwe ili m'gulu la banja la thermocouple, lodziwika chifukwa cha kutentha kwake komanso kukhazikika kwake. Amapangidwa ndi mawaya awiri achitsulo omwe amalumikizana pamodzi pamapeto amodzi, omwe amapangidwa ndi platinamu-rhodium alloys. Pankhani ya ma thermocouples a Type B, waya umodzi umapangidwa ndi 70% platinamu ndi 30% rhodium (Pt70Rh30), pomwe waya wina ndi 94% platinamu ndi 6% rhodium (Pt94Rh6).

Ma thermocouples amtundu wa B amapangidwa kuti athe kuyeza kutentha kwambiri, kuyambira 0 ° C mpaka 1820 ° C (32 ° F mpaka 3308 ° F). Amagwiritsidwa ntchito kwambiri ngati ng'anjo zamafakitale, ma kilns, ndi kuyesa kwa labotale yotentha kwambiri. Chifukwa cha kuphatikiza kolondola kwa zida zomwe zimagwiritsidwa ntchito, ma thermocouple a Type B amapereka kukhazikika komanso kulondola kwambiri, makamaka pakutentha kwambiri.

Ma thermocouples awa amakondedwa m'malo omwe kulondola kwambiri kumafunika, ngakhale kuti ndi okwera mtengo kuposa mitundu ina ya thermocouples. Kulondola kwawo komanso kukhazikika kwawo kumawapangitsa kukhala oyenera kufunsira ntchito m'mafakitale monga zakuthambo, zamagalimoto, ndi zitsulo.
