Za NTC Thermistors

Ma thermitors a NTC (Negative Temperature Coefficient) ndi masensa kutentha omwe kukana kwawo kumachepa kutentha kumawonjezeka.

B-Value Formula

Mtengo wa B ukuwonetsa mgwirizano pakati pa kukana ndi kutentha:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Kumene kutentha kumayenera kukhala ku Kelvin (K = °C + 273.15)

Steinhart-Hart Equation

Chitsanzo cholondola kwambiri chosinthira kukana kutentha:

1/T = A + B·ln(R) + C·[ln(R)]³

Kumene T ali mu Kelvin, R ndi kukana mu ohms, ndipo A, B, C ndi ma coefficients enieni a thermistor.

Njira yamtengo wapatali ya B imagwiritsa ntchito mtundu wosavuta womwe umatengera kuchuluka kwa B kosalekeza kudutsa kutentha. Equation ya Steinhart-Hart imapereka kulondola kwakukulu pogwiritsa ntchito ma coefficients atatu omwe amawerengera machitidwe osatsata mzere.
