[5] Resistance of Temperature Sensor
Thermistor for low temperature
Thermistor Ro= 15k ± 3% (TH3 ~ 9) Thermistor R120 = 7.465k ± 2% (TH1, 10)
R
t = 15exp {3460 ( - )} Rt = 7.465exp {4057 ( - )}
Thermistor R
o = 33k ± 1% (TH2) Thermistor R50 = 17k ± 2% (THHS)
Rt = 33exp {3965 ( - )} Rt = 17exp {4170 ( - )}
