The sensor is supplied with variable voltage of 0-30V and measured in a climatic room with temperature from -20°C to +80°C to obtain the current-voltage characteristic. Parameter extraction is used to control parameter changes of important sensor parameters such as resistances RTo and the temperature coefficient b of the thermistor itself in accordance to the temperature TM of the medium. The result of the parameter extraction gives RTo value 143.286 Ω at temperature of 373K, temperature coefficient b1 0.01 K-1 and b2 9.993 10-3 K-2 respectively and are used to reconstruct the R-T-curve.enCurrent-voltage curvesensor thermistorparameter extractionselfheated modeUR-Scientific Work Lecturer
