ABSTRACT
Thermistor is to use the semiconductor resistance with temperature significant change in the characteristics of components made of a thermal. Is sensitive to heat,the rate of resistance,small size and characteristics of small thermal inertia,is the temperature,the temperature control device important.Therefore,in the laboratory,biological thermometer,household appliances and industrial temperature applications such as very broad.
NTC thermistor is a negative temperature coefficient of thermal resistance, the resistance value of the product with increasing temperature lower, mainly used for temperature compensation, and temperature measurements in all types of power lines as the protection of components.
In the design of the thermal resistance characteristics of the nonlinear linear processing, through the acquisition of MATLAB data polynomial curve fitting to the design requirements.
