Pamusoro peNTC Thermistors

NTC (Negative Temperature Coefficient) ma thermistors ma sensor tembiricha ayo kupikisa kwawo kunodzikira sezvo tembiricha inowedzera.

B-Kukosha Formula

Iyo B-kukosha inoratidza hukama pakati pekupokana uye tembiricha:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Iko kunofanirwa kunge kuri tembiricha muKelvin (K = °C + 273.15)

Steinhart-Hart Equation

Imwe nzira yakanyatsojeka yekushandura kuramba kune tembiricha:

1/T = A + B·ln(R) + C·[ln(R)]³

Iko T iri muKelvin, R iri kuramba muohms, uye A, B, C ndiwo macoefficients akananga kune thermistor.

Nzira yeB-value inoshandisa modhi yakarerutswa inotora B-value inoramba iripo patembiricha. Equation yeSteinhart-Hart inopa huchokwadi hwepamusoro nekushandisa macoefficients matatu anoverengera maitiro asina-mutsara.
