26 | DERIVACIÓN DE LA TEMPERATURA DEL TERMISTOR | GEOKON
B.2 RESISTENCIA DE TERMISTOR DE 10KΩ
Tipo de termistor: Sensor US 103JL1A
Ecuación para obtener la resistencia a la temperatura:
1
T =
A+B(LnR)+C(LnR)
ECUACIÓN 7: Resistencia de termistor de 10kΩ
Donde:
T = Temperatura en °C
LnR = Registro natural de la resistencia del termistor
–3
A = 1.127670 x 10
–4
B = 2.344442 x 10
–8
C = 8.476921 x 10
–11
C = 1.175122 x 10
Nota: Los coeficientes optimizados para un termistor curva J entre las temperaturas de
0 ºC y +250 ºC.
