Calibration Device for Test Sieves Based on Image Measuring Instrument

摘要

The test sieves are widely used, but the calibration of the test sieves have the disadvantages of time consuming, low objectivity and accuracy. In order to solve these problems, the calibration device for test sieves based on image measuring instrument is designed and developed. Firstly, the design idea and principle of the calibration device for the test sieves are introduced. Secondly, the hardware and software system of the calibration device are studied. Finally, the reliability of the calibration device is verified by the stability and comparison experiment. Due to the successful development of this calibration device for test sieves based on image measuring instrument, automatically calibration, high accuracy, improvement of efficiency and reduction of labor intensity are achieved.
