Makorukureta eThermistor eNTC (XIXITRONICS)
Verenga B-value kana Temperature uchishandisa Steinhart-Hart Equation

Nezve NTC Thermistors
Mathermistori eNTC (Negative Temperature Coefficient) inyanzvi dzinoona tembiricha dzine resistance inoderera kana tembiricha ichiwedzera.
Fomura yeB-Value
B-value inotsanangura hukama huripo pakati pekudzivirira nekupisa:
B = [ln(R₁/R₂)] / [(1/T₁) - (1/T₂)]
Kupi tembiricha dzinofanira kunge dziri muKelvin (K = °C + 273.15)
Steinhart-Hart Equation
Muenzaniso wakanyatsojeka wekushandura kuramba tembiricha:
1/T = A + B·ln(R) + C·[ln(R)]³
Apo T iri muKelvin, R isimba mu ohms, uye A, B, C i coefficients chaiyo kune thermistor.
Nzira yeB-value inoshandisa modhi iri nyore iyo inofungidzira kuti B-value inogara iripo pakati petembiricha. Equation yaSteinhart-Hart inopa kururama kwakanyanya nekushandisa ma coefficient matatu anotsanangura maitiro asina kurongeka.
