Add to Cart
The grating linear scale measurement technology is a digital sensor technology integrating optics and electromechanics.
It uses photoelectric conversion technology to convert mechanical position information into digital signal output.
It has the advantages of high measurement accuracy, fast speed, good stability, and strong anti-interference ability.
It is widely used in the measurement of machine tool processing accuracy.
Product Description
Advanced Optical Measuring System
The reading head moves along the small friction guide rail of the grating ruler. The reading head is connected to the external mounting frame through a coupling. The coupling can compensate for the inevitable alignment error between the grating ruler and the machine tool rail
Double Seals Design
The plastic seals of GS series scales use an innovative material to offer superior oil resistance, high elastic recovery properties and durability, carefully designed lips geometry offer low slide resistance.

100% Laser calibration
All glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy report in QR code
Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
