Banyere NTC Thermistors

NTC (Negative Temperature Coefficient) thermistors bụ ihe mmetụta okpomọkụ nke nguzogide ha na-ebelata ka okpomọkụ na-abawanye.

Ụdị B-Uru

Uru B na-akọwa mmekọrịta dị n'etiti nguzogide na okpomọkụ:

B = [ln (R₁/R₂)] / [(1/T₁) - (1/T₂)]

Ebe okpomọkụ ga-adị na Kelvin (K = °C + 273.15)

Steinhart-Hart nhata

Nlereanya ziri ezi maka ịtụgharị iguzogide okpomọkụ:

1/T = A + B·ln(R) + C·[ln(R)]³

Ebe T dị na Kelvin, R bụ nguzogide na ohms, na A, B, C bụ ọnụọgụgụ kpọmkwem maka thermistor.

Usoro B-uru na-eji ụdị dị mfe nke na-ewere uru B mgbe niile n'ofe oke okpomọkụ. Nha nhata Steinhart-Hart na-enye izi ezi dị elu site na iji ọnụọgụ atọ na-aza maka omume anaghị akwụ ụgwọ.
