System research and information technologies| Summary: | The objective of this research is to develop a circuit-based method for linearizing the temperature characteristics of thermistors using a polynomial digital technique for NTC-thermistor temperature characteristics, together with the characteristics of the designed measurement channel, by means of an original MATLAB Simulink model. A model of a temperature-measurement device employing a thermistor-based sensor is proposed. The polynomial digital method for linearizing the temperature characteristics of NTC thermistors in the developed device has been simulated. To improve measurement accuracy, the components of the measurement channel were selected such that they enable simulation with minimal error. Methods for introducing correction-coefficient values into the model have been determined to compensate for error-inducing factors, including the thermistor’s self-heating effect. The proposed data-processing algorithm offers advantages for implementation in a low-cost, low-power microcontroller. |
