Abstract

To expand the scope of measurement

the testing circuit is based on the constant frequency carrier AM measurement circuits

and exponential computing circuit is used as non-linearity compensation.Using simulation software Matlab

the eddy current sensor probe of diameter 60 mm is designed

and experiment is done with the measurement circuit.Experimental results show that the eddy current sensor can detect the distance of 90 mm

it’s validated by experiment that the sensor works steadily

and reaches the expectant effect.
