The principle is to measure the correlation between the capacitance change and the length change when the opposite area of the parallel plate capacitor moves relative to each other, which is the same as the principle of the existing capacitive grid displacement sensor; the slider is an inverted "C" shape as a whole; the driving component is arranged on the fixed scale sleeve and connected to the slider, wherein the driving component includes a power member and a transmission member connected to the power member; the power member is installed at the top position of the other end of the fixed scale sleeve, and the transmission member is arranged inside the fixed scale sleeve and connected to the slider.
[0006] As a preferred technical solution in the utility model, columns are fixed at both ends of the fixed ruler sleeve, and the transmission member includes a synchronous wheel rotatably mounted on the two columns, and a synchronous belt mounted on the two synchronous wheels. When the synchronous wheel rotates, the synchronous belt is synchronously driven to rotate. The synchronous belt is located on the inner side of the slide, and a fastening bolt is fixed between the synchronous belt and the top position of the inner side of one end of the slide.
[0007] As a preferred technical solution in the utility model, the power part includes a small motor installed on the outside of the other end of the fixed scale sleeve, the output end of the small motor passes through the interior of the fixed scale sleeve, and a driving gear disc is also installed on the output end of the small motor; a bevel gear is fixed at one end of the synchronous wheel located at the internal position of the other end of the fixed scale sleeve, and the bevel gear is meshed and connected with the driving gear disc.

The controller is located on the inner side of the synchronous belt and does not contact the synchronous belt to avoid affecting the normal rotation of the synchronous belt.
[0009] As a preferred technical solution in the utility model, the connecting wires do not contact the column, the synchronous belt, and the inner wall of the fixed ruler sleeve. The separate setting can improve the safety of the connecting wires and avoid leakage caused by wear.
