Linierisasi Sensor Termistor Ntc (Negative Temperature Coefficient) Berbasis Rangkaian Paralel

---

Many sensors show a nonlinear relationship between their input and output. Due to this nonlinearity, direct reading of the sensor across its sensing range is difficult. The NTC (Negative Temperature Coefficient) thermistor is a temperature sensor that exhibits nonlinear characteristics between resistance and temperature, in which its resistance decreases as the temperature increases. This research proposes a linearization technique to compensate for the nonlinearity of NTC thermistors using parallel circuits. The NTC thermistor type used is B57891M0104 (R_25=100 kΩ). The values of the parallel resistor variations used based on the calculations are 20 kΩ, 27 kΩ, 37 kΩ, dan 47 kΩ. The results showed that R_P=27 kΩ yielded a linear graph. The coefficient of determination obtained R²=0.993 and the sensitivity value "S(T)"=246.61 Ω/"K" .
