Rt thermistor resistance at Tt R thermistor resistance at T, usually room temperature, 0 0 298. 16K ( 25 C) I R thermistor resistance at T oo, and 00 t 3 beta, a parameter which is a property of the thermistor material. Since temperature measurement is defined in terms of the thermalJul 22, 2011 When resistance vs. temperature linearization is desired, the resistor should be connected in parallel with the thermistor. Because when I try to use parallel resistor approach, I got the same graph as yours which you used series resistor. The output voltage vs. temperature linearized not the resistance vs. temperature linearization. I wonder linearization of thermistor resistance temperature characteristics

Thermistors are available in two types: PTC (positive temperature coefficient) and NTC (negative temperature coefficient). The resistance of a PTC thermistor increases as the temperature increases. In contrast, the resistance of an NTC thermistor decreases as temperature increases, and this type seems to be the most commonly used thermistor.

PSpice was used to determine the RT characteristics of the PS203J2 thermistor over a 0C to 150C temperature range. The thermistor was driven with a constant current source and the voltage was measured across the thermistor while performing a DC sweep of the temperature parameter, Temperature. Then, using the cursor function, the values of R T

Aug 26, 2008 A linear relationship is obtained between the temperature of a thermistor and the voltage output from an electronic circuit into which the thermistor is incorporated. The circuit is basically a combination of a logarithmic amplifier and an analog divider. It is capable of producing a linear voltage output with temperature for virtually all commercially used thermistors having resistance in the
