Extensómetro recuperable modelo 1300 (A-9)

Apéndice B.Derivación de la temperatura del termistor

Resistencia de termistor de 3kΩ

Tipos de termistor:

■YSI 44005, Dale #1C3001–B3, Alpha #13A3001–B3

■Honeywell 192–302LET–A01

Ecuación para obtener la resistencia a la temperatura:

T =	1	– 273.15 °C
	A+B(LnR)+C(LnR)³

ecuación 7: Resistencia de termistor de 3kΩ

Donde:

T = Temperatura en °C

LnR = Registro natural de la resistencia del termistor

A = 1.4051 x 10^–3

B = 2.369 x 10^–4

C = 1.019 x 10^–7

Nota: Coeficientes calculados entre los –50 y los +150 °C.
