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.

Mini Mill Dro Kit Metrology DRO Digital Readout Absolute Linear Scale 0

Easson have seriously invested in the development of absolute linear scales since 2010, after 2 years of hard works, Easson have launched the first three series of absolute linear scale at 2012. On 2014 Easson have completed the development of the absolute linear scales, offering comprehensive choices to our customers.

 

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.

 

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.

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.

 

Features and advantages:

1. High Accuracy

2. Convenient to use
