Mayelana ne-NTC Thermistors

Ama-thermistor e-NTC (Negative Temperature Coefficient) yizinzwa zokushisa ezimelana nazo kwehla njengoba izinga lokushisa likhuphuka.

Ifomula Yenani Eli-B

Inani le-B lichaza ubudlelwano phakathi kokumelana nokushisa:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Lapho amazinga okushisa kumele abe ku-Kelvin (K = °C + 273.15)

Isibalo sikaSteinhart-Hart

Imodeli enembe kakhudlwana yokuguqula ukumelana nokushisa:

1/T = A + B·ln(R) + C·[ln(R)]³

Lapho u-T eku-Kelvin, u-R uwukumelana kuma-ohms, kanti u-A, u-B, u-C yizinhlanganisela ezithile ku-thermistor.

Indlela ye-B-value isebenzisa imodeli elula ethatha i-B-value engaguquki kulo lonke uhla lokushisa. I-Steinhart-Hart equation inikeza ukunemba okuphezulu ngokusebenzisa ama-coefficient amathathu achaza ukuziphatha okungekho emgqeni.
