| Abstract: | With the fundamental principle of magnet-elastic effect and electromagnetic induction,a sensor for mechanical damage inspection was designed.The design of measuring circuit and software was explained. The factors of influencing signal accuracy were analyzed.The experimental results show that the sensor can characterize mechanical damage such as gouges or dents effectively.Furthermore,the NLH sensor has such advantages as miniaturization,low noise and low power consumption, which is suitable for on-line inspection for mechanical damage in pipelines. |
