Bayanin Samfurin
Wayar Thermocouple Type B
Bayanin Samfuri
Wayar thermocouple ta Type B wata na'urar thermocouple ce mai ƙarfi wadda ta ƙunshi ƙarfe guda biyu masu ƙarfe: ƙafa mai kyau wacce ke da kashi 30% na rhodium da kashi 70% na platinum, da kuma ƙafa mai korau wacce ke da kashi 6% na rhodium da kashi 94% na platinum. An ƙera ta ne don yanayin zafi mai tsanani, ita ce mafi jure zafi a tsakanin na'urorin thermocouple na ƙarfe masu daraja, tana da kyau a cikin kwanciyar hankali da juriya ga iskar shaka a yanayin zafi da ya wuce 1500°C. Haɗaɗɗiyar ta musamman ta platinum-rhodium mai nau'i biyu tana rage ɗigon ruwa da fitar da platinum ke haifarwa, wanda hakan ya sa ta dace da auna zafin jiki mai yawa na dogon lokaci.
