  • Sound-card-based Johnson noise thermometer [Elektronski vir]
    Tavčar, Rok ; Bojkovski, Jovan ; Beguš, Samo
    This article presents a Johnson noise thermometer with a signal acquisition system based on a sound card. The thermometer uses a simple analogue circuit to measure the Johnson noise on a resistor. No ... external hardware or power supply is necessary, except for a reference multimeter. Data processing is performed in real time on a personal computer using LabView software. The results show that the developed thermometer has an expanded uncertainty (k = 2) of 0.8 °C over a temperature range from − 196 °C to 300 °C, with a measurement time of 5 min.
