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.

—— A***r

Material conforms to the order very well packs works very well. Very fast shipment after Chinese New Year

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.

High Accuracy Two Grating Masks Absolute Linear Scale Digital Readout For Metrology 3

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.

 

High Accuracy Vertical 5 Bearings Design Absolute Linear Encoder with Digital Readout Dro 3

EC-1 is an absolute code designed by Easson for absolute grating scale. Compared with Heidenhain's 20mm distance code, epson EC-1 has the following advantages:

 

1. Heidenhain's distance code is a kind of "Codified Mark" that uses a small mark within 20mm as a distance signal trigger, while EC-1 uses a normal 0.82mm width REF Mark as a position mark, so the dust resistance is better than Heidenhain's is better and has less chance of misreading.

2. EC-1 adopts a dual-code combination design, with the possibility of error detection, so it is easy to embed error detection and correction procedures.

3. The detection movement distance of EC-1 is 6.1~12.1mm, which is shorter than Heidenhain's "Codified Mark" and is more convenient to use.
