Abstract :
We have developed the sinusoidal excitation type parametric magnetic sensor. A sinusoidal oscillator with the exciting frequency of twice the parametric oscillation frequency is needed in order to make parametric oscillation. In this digest, we propose that the parametric magnetic sensor is more simple and portable with a pulse oscillator instead of a sinusoidal oscillator, and we clarify that the pulse excitation type parametric magnetic sensor has excellent characteristics.
