Abstract

PURPOSE: To enable the displacement detection with high accuracy, by less number of coils, by forming the transducer with two coils wound on the same center shaft and the moving core moving in the space on the center shaft and connecting the oscillation circuit to each coil.
CONSTITUTION: Two coils L1, L2 are wound on the left and right of the bobbin 1 with the number of same windings as one layer of arranging winding, and the moving core 2 connected to the displacement object to be detected externally in the space on the center axis is located. Further, the coils L1, L2 are connected to the oscillation circuits OSC1 and OSC2, and the output is input to the microcomputer CP1 via the NOR circuit NOR1, and the output of CP1 gates the oscillation circuits OSC1, OSC2 and output it to the display LD1. Accordingly, the primary winding is not required and the detection is made in frequency, allowing less number of windings, and the coil is simplfied and the displacement detection with high accuracy can be made.
