Mayelana ne-NTC Thermistors

I-NTC (Negative Temperature Coefficient) izinzwa zokushisa izinzwa okumelana kwazo kwehla njengoba izinga lokushisa likhuphuka.

I-B-Value Formula

Inani B libonisa ubudlelwano phakathi kokumelana nezinga lokushisa:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Lapho amazinga okushisa kufanele abe se-Kelvin (K = °C + 273.15)

I-Steinhart-Hart Equation

Imodeli enembe kakhudlwana yokuguqula ukumelana nezinga lokushisa:

1/T = A + B·ln(R) + C·[ln(R)]³

Lapho u-T eku-Kelvin, u-R ewukumelana kuma-ohms, futhi A, B, C ama-coefficients aqondene ne-thermistor.

Indlela yenani lika-B isebenzisa imodeli eyenziwe lula ethatha inani elingu-B elingashintshi kulo lonke ibanga lokushisa. Isibalo se-Steinhart-Hart sinikeza ukunemba okuphezulu ngokusebenzisa ama-coefficient amathathu alandisa ngokuziphatha okungekona komugqa.
