Hais txog NTC Thermistors

NTC (Negative Temperature Coefficient) thermistors yog qhov ntsuas kub ntsuas uas nws tsis kam txo qis thaum kub nce.

B-Value Formula

B-tus nqi qhia txog kev sib raug zoo ntawm kev tiv thaiv thiab kub:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

Qhov twg kub yuav tsum nyob rau hauv Kelvin (K = ° C + 273.15)

Steinhart-Hart Equation

Tus qauv tseeb dua rau kev hloov ua haujlwm rau qhov kub thiab txias:

1/T = A + B·ln(R) + C·[ln(R)]³

Qhov twg T yog nyob rau hauv Kelvin, R yog kuj nyob rau hauv ohms, thiab A, B, C yog coefficients tshwj xeeb rau lub thermistor.

Txoj kev B-tus nqi siv tus qauv yooj yim uas xav tias qhov B-tus nqi tas li thoob plaws qhov kub thiab txias. Qhov sib npaug Steinhart-Hart muab qhov tseeb dua los ntawm kev siv peb cov coefficients uas suav nrog tus cwj pwm tsis zoo.
