本文报道了一种采用热解石墨（PG）的抗磁悬浮温度计。抗磁性材料的悬浮高度取决于温度。该系统由PG盘、驱动用永磁体、非接触式激光位移计和点加热器组成。我们评估了在空气和真空中改变PG盘温度的高度，并且盘在空气和真空中分别改变其高度为-1.49和1.55 µm/°C。介绍了聚苯乙烯的差热分析。指出了抗磁悬浮作为测量温度变化的新原理的潜力。© 2020日本电气工程师协会。由John Wiley & Sons公司出版
This paper reports a diamagnetic levitation thermometer using a pyrolytic graphite (PG). The levitation height of diamagnetic materials depends on the temperature. The system is composed of a PG disc, permanent magnet for driving, non‐contact laser displacement meter, and spot heater. We evaluated the height in air and vacuum changing the temperature of the PG disc, and the disc changes its height as to be −1.49 and 1.55 µm/°C in air and vacuum, respectively. Differential thermal analysis of polystyrene is demonstrated. The potential of the diamagnetic levitation as a new principle measuring temperature changes is indicated. © 2020 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
