Ma'aunin zafin jiki na Juriya na Platinum

Hakazalika da thermistors, na'urori masu auna zafin jiki na platinum (RTDs) su ne masu zafin zafi da aka yi da platinum.

Na'urori masu auna zafin juriya na Platinum suna amfani da halayen ƙarfe na platinum don auna zafin jiki ta hanyar canza ƙimar juriyarsa lokacin da yanayin zafi ya canza, kuma kayan nuni zai nuna ƙimar zafin jiki daidai da ƙimar juriya na juriyar platinum. Lokacin da akwai ma'aunin zafin jiki a cikin ma'aunin da aka auna, ma'aunin zafin jiki shine matsakaicin zazzabi na matsakaicin Layer tsakanin kewayon nau'in ji.

Ana iya raba juriya ta Platinum zuwa ultra-low zafin jiki, ƙananan zafin jiki, matsakaicin zafin jiki da matsanancin zafin jiki bisa ga ma'aunin zafin jiki, wanda
Matsakaicin zafin jiki: -196 ° C zuwa +150 ° C,
ƙananan zafin jiki: -50 ° C zuwa +400 ° C,
matsakaicin zafin jiki: -70 ° C zuwa + 500 ° C, da
Za a iya amfani da babban zafin jiki don auna zafin jiki har zuwa 850 ° C.
