Development of the High-Precision Intelligent Coating Thickness Gauge

  • 摘要: 针对铁磁性基体材料上非铁磁性薄涂镀层厚度测量的问题, 研制了一种智能型、高精度涡流测厚仪。包括专用磁屏蔽探头, 高稳定性、低漂移信号源, 低噪声、高精度放大接收电路及具有多种标定和补偿功能的系统软件。利用该涡流测厚仪对铁磁性材料基体上镀锌层厚度进行测量的结果表明, 仪器测量范围0~30 μm, 测量精度达到0.5 μm±3%测量值, 最小测量面积 5 mm2, 能满足薄涂镀层厚度测量要求。可广泛应用于各种平面、异型面铁磁性基体上非磁性薄涂镀层厚度的测量, 具有良好的市场应用前景。
    Abstract: An intelligent and high-precision eddy current thickness measuring gauge for thin nonmagnetic coating thickness measurement on magnetic substrate was researched and developed. The system included the special probe with magnetostatic shielding, the signal generator with high stability and low-drift, low noise and high precision amplifier, the system software with the function of multiple calibration and compensation. The measuring result for the zinc coating on magnetic substrate using the gauge showed that the measuring range was from 0 to 30 μm, the measuring precision could meet 0.5 μm±3%(measurement value) and the diameter of the minimal measurement area was  5 mm2, which was satisfactory for the measurement of high-precision coating thickness. The application prospect of this gauge was bright.
