50 - 3000mm Easson 2 Axis Lcd Dro Readout For Machine Tools

50 - 3000mm TTL Signal Easson 2 Axis Lcd Dro Readout For Machine Tools

Product Introduction

The EA series is one of the new digital readout systems with all in one function develop by Easson. It is a practical, multifunctional optical glass scale digital display for manual machine tools like Milling, Lathe, Boring machine etc.

The design is to ensure the fully function and high quality, try to use the most reasonable solution reduce the price to improve product competitiveness.

The Autotex is used as the key membrance of EA series, it offer excellent chemical resistance to most commonly used industry solvent and excellent switch life, switch life of expected to be 100,000 times.

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 standard specification, we have a complete set of EMC test esd immunity tester.


Easson DRO have been to conforms to relevant standards for the electromagnetic compatibility ( EMC ) as the 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 )

Aging Test

.

Easson DRO need to do the aging test, using 3 axis signal generator counting, make sure all couting reading correctly, high temperature test and load test for 3 days before QC procedure.

Easson 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.

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.
