Product Description
Advanced Optical Measuring System
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.
Features:
1. The slide carrier of the scales, using 5 bearing design and 6 spring for optical grating linear encoder sensor
2. VS/VA 20 series can connect a positive press system to reach waterproof IP65.
3. Moving speed can more than 120m/min.
Aging Test
Aging test exposes defects in the process, design, materials and other aspects of electronic devices before they leave the factory. Hence, it is of great significance for companies to modify product designs in time in order to the products can be sold after they are aging and stable, thereby improving product quality and market reputation.
100% Laser calibration
All Easson glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
