Lathe Digital Readout Kit 50 - 1250mm Length Absolute Linear Encoders

Best Quality Vertical 6 Springs Design Absolute Linear Encoder with Digital Readout Dro

Advanced Optical Measuring System

Principal of Absolute Linear Scale

The grating scale of absolute linear scale consists of two grating masks, they are Absolute Grating Mask and Incremental Grating Mask respectively. Functions of this two masks are as per follows :

Absolute Grating Mask have different mask pattern over the whole grating glass, it gives low resolution but unique position readings over the whole measurement travel.

Incremental Grating Mask is an identical repeatable mask patterns over the whole grating glass, it gives very stable and high quality electronic signal for signal interpolation to achieve very high accuracy and resolution position readings.

Absolute Coding

All absolute coding used in our Absolute Grating Mask are designed by Easson, it is 100% our in-house design and intellectual property, designed and developed for different requirements of applications.

Aging Test

Optical Linear Scale's reader head need to power on for 72 hours aging test before assemble, make sure all linear scale's quality is reliable.

Installation Dimensions

VA10 / VA11 / VA12 / VA13 Series

Connector interface

Absolute linear scale output signal

AS series absolute linear scales offering wide variety choices of output signal interface for different cost, resolution, speed and reliability considerations. Customers can order the most suitable type of output signal interface which optimized to the best of their application and cost requirement.

100% Laser calibration

All glass scale are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.

Easson was established since 1995.It is a high-tech enterprise specializing in design and manufacturing of precision measuring equipment, obtained more than 20 national invention and utility model patents. Our product field in DRO systems, precision optical profile projectors, video measuring machine and etc..

Easson's factory building is specifically design and built for the manufacturing of precision measuring equipment, has four Laser interferometers for being the company's length measurement standard and R&D.

Easson is one of the few companies in the industry that has its own high-precision grating master which use own fully-developed grating master lithography equipment, produce the absolute linear encoder and high accuracy CNC linear encoder.

Our quality management system has been assessed and registered by National Quality Assurance Ltd.(NQA) against the provision of ISO 9001:2015.

Strong Technical Capabilities And Scientific Research Resources

Over the years, the company has established a very close and effective cooperative relationship with scientific research institutions such as Xi'an Jiaotong University and Jilin University, taking advantage of the abundant talents and theoretical advantages of university scientific research institutions, combined with the company's long-term accumulated technology and practical experience in this industry , so that we have created many products that are leading the domestic industry.

In addition, the company actively participates in the scientific research and industrialization projects issued by the state and Zhuhai City.

For example, in 2011, the company participated in the "High-end CNC Machine Tools and Basic Equipment" led by Xi'an Jiaotong University and issued by the Ministry of Industry and Information Technology of China "Science and Technology Major Project. And combined with Tianjin University, Hefei University of Technology, Chinese Academy of Metrology... and other units jointly developed.

The company's AS-40 series grating ruler is one of the results of this project, which is industrialized by our company. And our company's EC-2 Pseudo-random absolute coding is one of the project achievements jointly developed by our company and Jilin University.

Actively participate in industry standard setting

Easson Measurement Technology Ltd. is one of the core members of the Digital Display Sub-Standard Committee of the National Measuring Tool and Measuring Instrument Standardization Technical Committee of China.

For a long time, it has actively participated in the formulation of various standards in the industry, and introduced the most advanced international standards in the industry. standards, and work together with peers to promote the development of the industry.
