Abstract

A remote temperature sensing system was investigated. The system can measure the temperature by applying an external magnetic flux to the sensor and by receiving a flux at the resonant frequency corresponding to the temperature at the sensor. The sensor does not need a power supply within it and is only composed of a temperature sensitive ferrite core and a wound coil. The inductance of the core varied from about 8-18 mH in the temperature region of 35-55°C. The induced voltage, ΔV by the sensor was about 10 mV for a 260 mm length between the transmitter and receiver. The system was successfully operated in our investigation.
