Abstract
The paper describes the use of magnetoelastic ribbon in a remote temperature sensor. Magnetoelastic ribbon was placed in an ac magnetic field generated by an external coil. The vibration of the ribbon was monitored with a pickup coil and reached its maximum value at the mechanical resonant frequency, in accordance with the magnetostriction effect. We monitored the temperature by measuring the output voltage of a pickup coil at frequencies near the resonance. The maximum change in output voltage was 0.57%°C-1, in the temperature range from 20°C to 80°C. This finding indicates the potential of the ribbon for use in a sensitive and compact remote temperature sensor.
