| 摘要 |
The invention relates to a device for measuring a thermal conductivity, comprising elements (10) for providing a heating voltage, elements (12) for providing a measuring current and elements (18) for generating a temperature-dependent voltage drop. The elements (10) for providing a heating voltage make available a heating voltage that alters over time. Said device is also provided with elements (14) for comparing the temperature-dependent voltage drop with a threshold voltage and for generating an output voltage that alters over time. The invention also relates to a method for measuring a thermal conductivity. |
