Customer Reviews
This DRO display is smaller than most and i am very happy with it. The controls are simplified and i have had no problem mastering it and using all features. I'm 71 years old. The Display information is bright white and very easy to see in all lighting conditions even with my poor eye sight. No green or red led lights to have to look at anymore.

Unit is legit and works and is very nice but I still have to set it up but this is much better than traditional dro displays. It shows the operations for the different functions it has.

Optical Linear Easson Dro

 Easson Multifunctional Optical Linear Scale 2 Axis Aluminum Shell Digital Readout Dro


Product Introduction

2 Axis Optical Linear Glass Scale Dro 0
EA-927 is the new all in one function digital readout systems by Easson launch in the year 2020.  It is a practical, multifunctional optical linear scale digital display have been applied to varieties of machine tools such as Milling, Lathe, Grinding, Boring machine etc. 


Working Principe


The digital display is a kind of appearance that has an analog-to-digital converter and displays the value of the measured variable in a decimal number method. It is matched with various sensors and dispensers to display various parameters. The digital appearance has the advantages of high precision, full function, fast speed, strong anti-interference ability, small size, low power consumption, intuitive readings.




Ultra Low Temperature Linear Power Transformer


2 Axis Optical Linear Glass Scale Dro 1 
All Easson digital readout display's power supply using a linear power transformer and power filter, this can help our products pass by the noice immunity and the EMC testing.

EMC Testing

All Easson Digital Readout products need to be pass the EMC standard specification, hence we have a complete set of EMC test esd immunity tester for the EMC testing.

2 Axis Optical Linear Glass Scale Dro 2
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


2 Axis Optical Linear Glass Scale Dro 3


Easson digital readout unit 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 x 24 hours before QC procedure.
