Vision and Commitment

EP-1 Profile Projectors



Easson Measurement started manufacturing Profile Projectors in the year 1999.
Since then more than 4'000 Profile Projectors have been sold all over the world and, at present, Easson is one of the key manufacturers, in this segment, in China. 
 
EP1 provides accurate 2D measurement for all common geometric features such as circles, lines, angles and etc...
All measured results can be printed or transfered to computer for further processing.
EP1 is ideal for all circuital dimension measurement, in mold and die making, form tools making, screw manufacturing, gear manufacturing and etc..

Geometric Functions   3 points circle measurement;

  point measurement;

  2 points distance measurement

  2 points form a line measurement;
    2 lines intersection measurement;
  4 points line intersection measurement;
  point-line perpendicular projection
Coordinates   Cartesian and Polar Coordinate Systems
Memory   99 features memory; 10 memory

EP-1 Part List
  

Control Panel includes: Power (On/Off); Direct Light Key: High; Direct Light Key: Low; Reflective Light Key;

 

EP1 is equipped with ES12 LCD Colour Digital Read Out, 1 micron resolution, which provides comprehensive and easy to use geometric measurement functions.
 
   
Printer is embedded in the ES12 P arm.


ES12 P Digital Read Out

Robust friction transmission system
To avoid the usual backlash problem of normal lead screw transmission system, rod base friction transmission system are used in the XY movements. This solution provides excellently smooth, sensitive and backlash free positioning that assure easy and precise measurements.

 
High precision linear guideway
High precision linear guideways are used in all X,Y and Z movements. This design provides very high straightness movements and consequently, high measurement accuracy.

 
High stability machine casting
To avoid deformation caused by the internal stress of the metal casting, in addition to the usual internal stress release process (by tempering), all EP-1 scasting are further stress released by a computer controlled vibration stress release. This process assures high dimensional stability and long lasting mearsuring accuracy.
