Acoustic-Seismic Detection Sensor的用法和样例：
- Introduced planar welding line detect sensor based on GMR.
- A three-dimensional welding line detect sensor based on GMR was introduced.
- Sniper Acoustic Detection Sensor
- Rayleigh wave detection as a shallow seismic detection method, characterized by advantenges of being simple and convenient, has been applied in many fields.
- Experiments of multi components distillation column (MCDC) showed that the above method can detect sensor fault in processes effectively and has preferable robustness.
