Ku bijyanye na NTC Thermistors

Ibipimo by'ubushyuhe bya NTC (Negative Temperature Coefficient) ni ibikoresho bipima ubushyuhe aho ubushobozi bwabyo bugabanuka uko ubushyuhe bwiyongera.

Formula y'agaciro ka B

Agaciro ka B kagaragaza isano iri hagati y’ubudahangarwa n’ubushyuhe:

B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]

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

Ikigereranyo cya Steinhart-Hart

Icyitegererezo cyiza kurushaho cyo guhindura ubushobozi bwo guhangana n'ubushyuhe:

1/T = A + B·ln(R) + C·[ln(R)]³

Aho T iri muri Kelvin, R ni resistance muri ohms, naho A, B, C ni coefficients yihariye kuri thermistor.

Uburyo bwa B-value bukoresha moderi yoroshye ifata agaciro ka B-gahoraho mu rugero rw'ubushyuhe. Igereranya rya Steinhart-Hart ritanga ubunyangamugayo bwo hejuru hakoreshejwe ibipimo bitatu bigaragaza imyitwarire idahuje n'umurongo.
