| Abstract(in English) | Eddy-current type proximity sensor detects the approach of conductors by increasement of loss in the excitation coil due to eddy-current in target conductors. In consequence of high frequency excitation of about 100k to 1MHz, several magnetic losses, such as AC losses in coil or loss in ferrite core, occur in the sensor system. Therefore, it is required to take into account these losses for accurate performance prediction of the sensor. This paper investigates about FEM analysis of the sensor with consideration of eddy-current loss in coil and complex permeability of ferrite core for the computation of loss. Research results show the electoromagnetic influences of these losses to performance and knowledges about sensitivity or operating condition of the target sensor. |
