Annotations languages:

The device for precision measurement of temperature difference at the thermistor was developed. The proposed methodology of measuring the temperature difference and its practical implementation was considered. The block diagram of the developed device for precision measurement of temperature difference at the thermistor was shown in the article. The above features of the device calibration methods and the results of its metrological studies based on the theory of uncertainty in measurements.
Keywords: thermistor, temperature difference, circuit implementation, calibration, uncertainty
