摘要
根据电磁感应原理 ,以 PC计算机系统为核心 ,设计了一种由计算机控制的涡流检测仪器。通过阻抗分析识别缺陷 ,采用分扇区方式报警 ,可有效抑制掉干扰噪声 ,提高信噪比 ,降低漏报、误报率 ,且性能可靠 。
An instrument based on the principle of electromagnetic induction was developed for eddy current testing,which controlled by computer.The existing problems such as the disturbance of single,uncomfortable adjusting and insatiable state etc.were solved in original device.
