Design and Implementation of Metal Detection Based on Eddy Current Sensor

Abstract:

Article Preview

We present metal detection using eddy current sensors by combining 2 high-frequency sensors and 1 low-frequency transducer together on the basis of eddy current effect. The two high frequency sensors in this design work at different frequencies which implement the complementary of linear range of the detection and the analog signal is transformed into digital signal by ADC for further processing using ARM9 processor to achieve wide range, high sensitivity, and precise metal detection.
