The Application of Amorphous Soft Magnetic Alloy in Sensor's Elements

The properties of the Wiegand-type sharp voltage pulses and detectment of the small pressures,the static magnetic field and the displacement have been reaserched for the highly magnetostrictive Fe-based amorphous ribbons and wires,low or zero magnetostrictive Co-based ribbons and wires used for sensor's elements.The Fe-based amorphous ribbon-woud cores have good linearity and very high sensitivity.The sensitivity to pressure is high as 2.7V/N.Cobaese amorphous ribbons have good linearly and sensitivity (14mV/A·m^-1).The sensitivity to displacement is 30mV/mm,and the linear range is about 100mm
