Abstract
A novel noncontact current sensor based on Co-rich amorphous alloy ribbon is presented. Differing from the formerly reported sensors, a permanent magnet is used to supply bias magnetic field. The driving signal is provided by CMOS IC oscillator. The sensitivity of final sensor response reaches up to 461 mV/A, and the error of measurement repeatability is less than 0.1%.
