3.5. THERMISTOR TEMPERATURE DERIVATION

Resistance to Temperature Equation:

Equation to Convert Thermistor Resistance to Temperature
The explanation for symbols are; 


T = Temperature in °C. 


LnR = Natural Log of Thermistor Resistance


A = 1.4051 × 10-3 (coefficients calculated over the −50 to +150° C. span)

B = 2.369 × 10-4 , C = 1.019 × 10-7
