§≡≡≡≡  Description  ≡≡≡≡


Thanks to precision linear encoder system, long-life patented precision rail, high-end servo motor,patented non-reflective light source, high-resolution CCD camera, SJ2620 measures dialindicators accurately and automatically by applying with accurate control technology of glass-scale displacement and the intelligent image processing technology. A motor controlled by computer drives glass-scale to travel accurately; All data areacquired by software automatically without manual sampling; Indication values of test object are identified automatically by CCD camera which completely simulates manual reading; That Significantly reduces human labour and brainwork, as well as improves the testing speed. 
SJ2620 is a fully automated testing machine. The operator only needs to install the dial indicator and select few parameters insoftware,then the machine measures automatically in accordance with selected norm after click the "Start" button. After measurement, the test data and report can be generated and printed quickly(including data list of measuring points, error carve of forward—reverse measuresurement, qualification& eligibility level of indication errors, etc.)


§≡≡≡≡     Features    ≡≡≡≡

1. Artificial intelligence: Do not need manual reading & recording & calculating and manual adjustment with hand wheel or microdrum.
    (1) Scale and indication value are identified automatically by the CCD camera which completely simulates manual reading, without observed, read and recorded by operator
   (2) Function of automatic zeroing without manual zeroing before testing;
   (3) A motor controlled by computer drives measuring spindle to arrive measuring point accurately, without manual adjustment by hand wheel or microdrum
   (4) Powerful software automatically processes and qualifies the measured data, finally generates test result, additionally all test records can be queried, displayed, saved, printed.
2. Special light source:
   (1) Patented no-reflective light source(Patent No.: ZL200620056214.1) 
   (2) If the surface of dial indicator is convex, the no-reflective light source is necessary to assure reliability of test data.
3. New patented slider:
National utility model patent(Patent No.: ZL201220239454.0)
Eliminate gap in forward – reverse measuring by reducing the wear between the slider and the guide rail;
High repeatability: significantly improve lifespan of the slider and guide rail.
4. Humanized design:
Thanks to user-friendly interface, operation of software is extremely simple. With Humanized design for both machine and software, the operator can be trained to use it in a short time. Particularly the system can identify pointer of dial indicator and acquire the indication value of object accurately even if the dial indicator is not in the right center of camera, so the dial indicator can be installed fast, and that simplifies the operating procedure and save operating time.
5. Large-capacity database
With built-in large-capacity storage space for database, the system can record and save all test records automatically.
6. Powerful print
Support user-defined template of report(curve, sheet or error value). Test data can be saved automatically, particularly a number of test reports can be printed at once.
