Malunga ne-NTC Thermistors

I-NTC (i-Negative Temperature Coefficient) izifudumezi zizivamvo zobushushu ezikwaziyo ukuxhathisa kwehla njengoko ubushushu bunyuka.

Ifomula yexabiso le-B

Ixabiso le-B libonisa ubudlelwane phakathi kokumelana nobushushu:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Apho amaqondo obushushu kufuneka abe eKelvin (K = °C + 273.15)

Steinhart-Hart Equation

Imodeli echaneke ngakumbi yokuguqula ukumelana nobushushu:

1/T = A + B·ln(R) + C·[ln(R)]³

Apho i-T ikwi-Kelvin, i-R iyaxhathisa kwi-ohms, kunye ne-A, B, C zi-coefficients ezikhethekileyo kwi-thermistor.

Indlela yexabiso le-B isebenzisa imodeli eyenziwe lula ethatha ixabiso le-B elingaguqukiyo kuluhlu lobushushu. I-equation ye-Steinhart-Hart inika ukuchaneka okuphezulu ngokusebenzisa i-coefficients ezintathu ezibala ukuziphatha okungahambiyo.
