摘要
在理论分析和大量模拟试验基础上研制了四频涡流检测仪。混频处理去除了电站热交换器管板干扰信号 ,提高了信噪比。现场使用证明 ,该仪器具有操作方便。
A four frequency eddy current inspection instrument was developed based on theoretical analysis and simulative tests. Frequency mixing processing eliminated the disturbance of the support plate for heat exchanger tubes and improved signal to noise ratio. On the spot application showed its advantages of easy operation, high speed inspection and high ability for anti disturbance.
