Improving the way of determination substances thermal physical characteristics by direct heating thermistor method

摘要

This work devoted to investigating for improving methods possibility of determining material thermal characteristics measured by direct heating thermistor method and selecting the optimum settings heating sensor. Presented the results of experimental researches with control fluids with the help of the developed device, which gave an opportunity to evaluate the effectiveness of the proposed improvements. Recommended to reduce errors in the measurement by direct heating thermistor used method of determining thermal conductivity materials thermistor temperature under heating pulse of electric current with regard to thermal characteristics thermistor probe, thermistor power changes during it's heating and temperature of the sample.
