| Abstract: | The principle and technical difficulties of magnetic memory testing technology are introduced,the problem of weak magnetic signal is solved by means of array probe design and signal processing.Array probe can eliminate external magnetic signal interference,ensure the consistency between signals.This design can obtain the surface magnetic field distribution map of buried pipeline,also the source of abnormal magnetic signal can be confirmed.The developed instrument can effectively detect the weak magnetic signal of buried pipeline. |
| Keywords: | buried metal pipeline magnetic signal array probe stress |
