Product Description
Advanced Optical Measuring System
The slide carrier of the VS / VA series scales, use a five bearing design and six spring for optical grating linear transducer, make sure the VA scales not effected by installation, the spring can adjust the angle when the operator install not good for the alignment.
The reader head still in the best way fir on the grating glass, the accuracy of VA scale is totally different with the GS or other brand in China mainland.
VA scale has a small PCB inside the 9 PIN connector, the laser compensation data is store inside, with our LCD Digital display unit, the compensation data will directly load the ECF file (compensation file) into the DRO, accuracy up to ±2μm.
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.
