Abstract
This paper describes the application of remote temperature sensors made of an amorphous magnetic ribbon and a low Curie temperature ferrite tube to the measurement of temperature in an arbitrary range. By combining an amorphous magnetic ribbon and a ferrite tube with a Curie temperature of 40 °C, a resonant frequency change rate of 6.3%/°C was realized in the 35 to 40 °C temperature range. Similarly, by combining an amorphous magnetic ribbon and a ferrite tube with a Curie temperature of 47 °C, a resonant frequency change rate of 4.9%/°C was achieved in the 41 to 47 °C temperature range. These values are ∼100 times larger than that of the previously reported remote temperature sensor made only of an amorphous ribbon. Therefore, this confirms that a highly sensitive remote temperature sensor can be realized in an arbitrary temperature range. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
