【Abstract】 In this paper, based on the background of the under ground metal pipe line detector and the design principle of inductive magnetic sensors, we design a specific sensor. We improve this inductive magnetic sensor by using the amorphous alloy core for a superior sensitivity and high SNR(Signal to Noise Ratio). As the result reveals, we get a satisfactory conclusion.更多还原
