| Abstract: | In order to increase the sensitivity and detecting distance of common eddy current sensor,this paper analyzed a novel eddy-current sensor theoretically.The structures of the double-coil eddy current sensors and three coaxial coil eddy current sensor are listed.The paper analyzes the three coaxial coil eddy current sensor,deducts the method of designing the sensor's dimensions through electromagnetic field theory and introduces the testing circuit unit.As a conclusion,compared with common eddy-current sensor,the novel sensor has a longer detection distance and higher sensitivity. |
