Abstract
Wiegand wire generates a sharp voltage pulse in a coil wrapped around the wire when an applied magnetic field crosses a threshold intensity. Few papers have reported the characteristics of the output pulse from the point of practical applications.
Detailed study have been performed on the frequency characteristics of the amplitude of output pulse and of the threshold intensity of the applied magnetic field.
Although the amplitude of the pulse and the threshold value of the applied field depend to some degree on the exciting frequency, the experiments show that the fluctuations of the amplitude of the output pulse and those of the threshold value of the applied field are reduced when the maximum intensity of the applied field is three times as much as the threshold intensity of the field.
According to the results, the angular accelerometer using Wiegand wire has been made, which can measure angular speed and acceleration within an error of 1% in the wide range of angular speed.
