A new type of inductive sensor devices is studied. The basic working principle of the sensor, structure of the aperture identification system, analysis of experimental verification and industrial applications are presented amphatically. A new testing system was built by means of the distance relationship between the analog current output value of inductive sensor and the measured metal object to implement the identification of the different diameter screws installed on mechanical equipments. The experimental result obtained in the laboratory is consistent with the theoretical calculation value. The new detection system is practical, reliable, and also has the advantages of low cost, high stability coefficient, high accuracy and wide measuring range.
