摘要
介绍一种全数字式智能多用途涡流频谱分析检测仪，该仪器采用多种激励方式，并用得里叶变换方法实时分析涡流的响应信号，计算和复原信号的主频及高次谐波分量，以实时有效检测，分析工作的缺陷或理化性能，可用于常规涡流，低频涡流，脉冲涡流及远场涡流的研究和漏磁探伤等场合。
The multi-purpose full-digital eddy current spectrometer is introduced.It uses multi-ex(?)iter and can real-time obtain the first harmonic and the high-order harmonic of eddy current signals with Fourier transform method for effective real-time inspection and analysis of defects and physical and chemical properties of workpieces.
