With a precise linear encoder system Long-lasting, patented precision rail High-end servo motor Patented non-glare light source, high-resolution CCD camera, measure dial indicators accurately and automatically, applied with precise control technology of glass scale movement. and intelligent image processing technology A computer-controlled motor drives the glass scale in precise motion. All data are acquired automatically by the software without manual sampling. The indication value of the test object is automatically determined by the CCD camera, which fully simulates manual reading. That greatly reduces the use of human labor and the use of the brain. It also helps increase testing speed as it is a fully automatic tester. The operator only needs to install a dial indicator and select a few parameters in the software. Then the machine will automatically measure according to the selected norm after clicking the “Start” button after measurement. Test data and reports can be quickly created and printed. (including data list of measurement points Forward error—reverse measurement characteristics and qualification levels of indication errors, etc.)

  1. Artificial Intelligence: No need to manually read and record and calculate. and adjusted by hand or microdrum
    (1) The scale value and indication value are automatically indicated by the CCD camera, which fully simulates manual reading. without noticing Read and recorded by the operator.
    (2) Automatic zeroing function without manual zeroing before testing.
    (3) A computer-controlled motor drives the measuring shaft to achieve precise measurement points without manual or microdrum adjustment.
    (4) Powerful software automatically processes and certifies the measured data, finally generating test results. Moreover, all test records can be queried, displayed, saved, printed.
  2. Special light source:
    (1) Patented non-glare light source (Patent number: ZL200620056214.1)
    (2) If the surface of the dial is convex A non-glare light source is necessary to ensure the reliability of the test data.
  3. New patented slider:
    National utility model patent (Patent number: ZL201220239454.0)
    Eliminates forward gap – back measurement by reducing wear between the slide and guide rail.
    High repeatability: Significantly improves the service life of sliders and guide rails.
  4. Man-made design:
    With a user-friendly interface The operation of the software is therefore very simple. With Humanized design for both machine and software. Operators can be trained to use it in a short time. Specifically, the system can accurately identify the pointer of the dial indicator and obtain the object’s indication even if the indicator is not centered on the right side of the camera. Therefore, the dial indicator can be quickly installed. And makes the work process easier and saves work time.
  5. Large capacity database
    With built-in large capacity storage for databases The system can automatically record and save all test records.
  6. Powerful typing
    Supports user-defined report templates (curve values, sheets, or error values). Test data can be recorded automatically. In particular, multiple test reports can be printed at the same time.
