All In One Grey Linear Scale 2 Axis Digital Readout For Milling Machine​
Product Features

ES series DRO feature:

1. High noise immunity & ( EMC ) design
2. Adaptable to poor electrical source
3. High Durability Switch Membrane
4. Robust Aluminum Casing
5. Ultra Low Temperature Rise Transformer
6. State of the Art Electronics Technology
7. Totally Sealed Enclosure

The enclosure of ES series is totally sealed to protect the electronics circuits against the hazardous environment is shop floor, such as dust, evaporated coolant fume from EDM machining and etc..
To avoid overheat of the PCB caused by totally sealed enclosure, metal front plate and panel is used is order to quickly dissipate the heat generated by the electronics circuit and an ultra low temperature rise transformer is used.

Ultra Low Temperature Rise Transformer

Easson all Digital readout power supply use a linear power transformer and power filter, this can help our products pass by the noice immunity and the EMC.

To reduce the total heat generation inside the ES DRO in order to obtain long working life. An ultra low temperature rise transformer that construct with very high permeability icron core is used, which effectively bring temperature rise to only about 5℃.


EMC Testing equipment

To Make sure all Easson DRO products can be pass the standard EMC testing, we have a complete set of EMC test esd immunity tester.
Ensure the digital readout system have been to conforms to relevant standards for EMC as details below:

IEC61000-4-2 / GB / T 17799-2: Electrostatic discharge immunity ( Contact discharge 6000V, air discharge 8000V )

IEC61000-4-4 / GB / T 17799-4: Electrical fast transient burst immunity ( pulse amplitude 2000V )

IEC61000-4-5 / GB / T 17799-5: Lightning surge immunity ( Superrimposed pulse voltage peak 2000V )

Technical Specification

Basic parameter is included as below:

ES series DRO advanced Functions: Non-linear error compensation



Advanced functions for Milling machine

Connector interface

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.
