Analysis of Circuit Parameters of Eddy Current Sensor
In order to improve the sensitivity of the eddy current sensor, a sensor measuring circuit based on the resonance method is designed in this paper. The working principle of eddy current sensor is introduced, the relationship between output voltage and inductance value is obtained by the analysis of the resonant circuit parameters, and then simulated by MATLAB software. Circuit parameters are optimized, and the various circuit parameters are obtained under the condition of considering the highest value of the linearity and sensitivity.
