There are special differences in composition and tracking methods.

In addition, Korean Patent Publication No. 10-1522194 (hereinafter referred to as'Patent Document 3') says, "The displacement of the elastic support and the girder is simultaneously measured by an electrical signal by a simple and robust installation structure, and the measured value is measured.
