- Abstract:
- In the field of coating thickness gauges till now the calibration method has been used, where with the coating thickness gauge the coating thickness, reproduced by the coating thickness standard has been measured. The difference between the coating thickness value reproduced by the coating thickness standard and the reading of the calibrated coating thickness gauge would give us in this case the correction in the mentioned calibration point. In the presentation a new calibration method of the coating thickness gauges will be described. A special measuring object with the changeable coating thickness has been measured simultaneously with the standard measuring instrument and the calibrated thickness gauge. The calibration device worked out for the applying of the proposed measuring method will be analysed and examined. Accuracy characteristics of the mentioned device will be given and measurement uncertainty of the calibration results will be analysed. The researching results show us that using the new method we can substantially increase the calibration accuracy of coating thickness gauges.
