Malunga ne-NTC Thermistors

Ii-thermistors ze-NTC (Negative Temperature Coefficient) zii-sensors zobushushu ezithi ukumelana kwazo kunciphe njengoko ubushushu busanda.

Ifomula yexabiso le-B

Ixabiso le-B lichaza ubudlelwane phakathi kokumelana nobushushu:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

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

I-Steinhart-Hart Equation

Imodeli echanekileyo ngakumbi yokuguqula ukumelana nobushushu:

1/T = A + B·ln(R) + C·[ln(R)]³

Apho u-T ekwiKelvin, u-R kukumelana kwi-ohms, kwaye u-A, u-B, u-C zii-coefficients ezithile kwi-thermistor.

Indlela ye-B-value isebenzisa imodeli elula ethatha ixabiso le-B elingaguqukiyo kulo lonke uhla lobushushu. I-Steinhart-Hart equation inika ukuchaneka okuphezulu ngokusebenzisa ii-coefficients ezintathu ezichaza ukuziphatha okungekho kumgca.
