Abstract. A method for multichannel temperature measurement is proposed, which consists in alternately supplying n resistance thermometers. The method makes it possible to increase the accuracy of measurement by weakening the influence of the resistance of the lines through which resistance thermometers are connected. A prototype of multichannel temper-ature converter is developed and used for the method testing.
Keywords: multichannel temperature measurement, measurement accuracy, microcontroller, resistance thermometer
