Reasonable price high accuracy High Sensitivity accelerometer vibration sensor (iepe)
The A25G acceleration sensor has the advantages of high sensitivity, good low-frequency response, and low background noise. It is suitable for low-frequency vibration testing occasions such as building vibration monitoring, earthquake detection, dam and bridge structure testing, ground and foundation vibration monitoring, geological structure research, etc.
