Abstract： |
The present invention provides counter type grating belt for switching digital displacement sensor and belongs to the field of displacement and strain sensor designing technology. The present invention features that the grating belt has gratings divided into several units of 3 or more gratings each, all the gratings in different units are numbered in the same order, and all the gratings with the same number are connected via a conducting block to the same wire for outputting signal to signal treating circuit. Furthermore, the grating belt may be separated into several parallel grating belts to simplify the connection. The present invention has reduced connecting lines for switching digital displacement sensor, simplified making process, and raised making and measuring precision. |
