Ibyerekeranye na NTC Thermistors

Ubushyuhe bwa NTC (Negative Temperature Coefficient) ni ibyuma byerekana ubushyuhe ubushyuhe bwabyo bugabanuka uko ubushyuhe bwiyongera.

B-Agaciro

B-agaciro karanga isano iri hagati yo guhangana nubushyuhe:

B = [ln (R₁ / R₂)] / [(1 / T₁) - (1 / T₂)]

Aho ubushyuhe bugomba kuba muri Kelvin (K = ° C + 273.15)

Ikigereranyo cya Hart

Icyitegererezo cyukuri cyo guhindura kurwanya ubushyuhe:

1 / T = A + B · ln (R) + C · [ln (R)] ³

Aho T iri muri Kelvin, R ni ukurwanya muri ohms, na A, B, C ni coefficient zihariye za thermistor.

Uburyo B-agaciro bukoresha icyitegererezo cyoroheje gifata B-agaciro gahoraho kurwego rwubushyuhe. Ikigereranyo cya Steinhart-Hart gitanga ibisobanuro byukuri ukoresheje coefficient eshatu zibara imyitwarire itari umurongo.
