Game da NTC Thermistor

NTC (Negative Temperature Coefficient) thermistors sune na'urori masu auna zafin jiki waɗanda juriyarsu ke raguwa yayin da zafin jiki ke ƙaruwa.

Formula mai darajar B

Ƙimar B tana nuna alaƙar da ke tsakanin juriya da zafin jiki:

B = [ln (R₁/R₂)] / [(1/T₁) - (1/T₂)]

Inda yanayin zafi ya kasance a Kelvin (K = ° C + 273.15)

Daidaiton Steinhart-Hart

Ingantacciyar ƙira don juriya zuwa zafin jiki:

1/T = A + B·ln(R) + C·[ln(R)]³

Inda T yake cikin Kelvin, R shine juriya a cikin ohms, kuma A, B, C sune ƙayyadaddun ƙididdiga ga thermistor.

Hanyar B-darajar tana amfani da samfurin da aka sauƙaƙa wanda ke ɗaukar ƙimar B akai-akai a cikin kewayon zafin jiki. Ma'auni na Steinhart-Hart yana samar da daidaito mafi girma ta hanyar amfani da ƙididdiga guda uku waɗanda ke ƙididdige ɗabi'a marasa layi.
