Mabapi le Li-Thermistors tsa NTC

Li-thermistor tsa NTC (Negative Temperature Coefficient) ke li-sensor tsa mocheso tseo khanyetso ea tsona e fokotsehang ha mocheso o ntse o eketseha.

Foromo ea Boleng ba B

Boleng ba B bo hlalosa kamano pakeng tsa khanyetso le mocheso:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Moo mocheso o lokelang ho ba ho Kelvin (K = °C + 273.15)

Tekanyo ea Steinhart-Hart

Mohlala o nepahetseng haholoanyane oa ho fetola khanyetso ea mocheso:

1/T = A + B·ln(R) + C·[ln(R)]³

Moo T e leng ho Kelvin, R ke khanyetso ho ohms, mme A, B, C ke di-coefficients tse ikgethang ho thermistor.

Mokhoa oa boleng ba B o sebelisa mohlala o nolofalitsoeng o nkang boleng ba B bo sa fetoheng ho pholletsa le mocheso o fapaneng. Tekanyo ea Steinhart-Hart e fana ka ho nepahala ho hoholo ka ho sebelisa li-coefficient tse tharo tse ikarabellang bakeng sa boitšoaro bo sa lateleng.
