To solve for temperature when resistance is known, yields the following equation: 3)(ln)(ln/1 RCRbaT ; Where: T = temperature in °K (Kelvin), a, b and c are equation constants, R = resistance in Ω at temp T; To solve for resistance when the temperature is known, the form of the equation is: 27 2 2 227 2 2 xxxx R Where: c Tax /1 , c b . The a, b and c constants can be calculated for either a thermistor material or for individual values of the thermistors within a material type. To solve for the constants, three sets of data must be used. Normally, for a temperature range, the low end, middle end and high end values are used to calculate the constants, resulting in the best fit for the equation over the range. Using the Steinhart-Hart equation allows for accuracy as good as ±0.001°C over a 100°C temperature span. e
