Calculating Temperature from Resistance — North Star Sensors
We provide with explanation an Excel calculator to determine the temperature of an NTC thermistor given it's resistance. We use the 4-term Steinhart-Hart equation which is superior to the more common 3-term Steinhart-Hart equation. The Beta value, resistance-temperature ratio, and NTC value of a thermistor is also discussed.
The Secret To Successful Thermistor Beta Calculations
Thermistor Beta Calculations use a two-point calibration to calculate the resistance vs the temperature curve and take into consideration the required resistance at both temperature points. The Beta Value is measured in degrees Kelvin rather than Fahrenheit or Celsius, and it is calculated using the four components listed below.
