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.

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.

The company participated in the drafting of many national and industry standards, such as industry standard JB/T 10080.1-2011 "Graster Digital Display Instrument", JB/T10080.2-2011 "Graster Linear Displacement Sensor", etc. JB/T 11505-2012 "Displacement Sensor" Encoder CPE-Bus bidirectional serial communication protocol specification".....
