YMC Series the High Sensitivity Accelerometer is specifically designed to detect the ultra–low vibration, low frequency vibration. This series is applied for the bridge structural testing, vibration monitoring, earthquake monit oring and early warning, ground and foundation vibration monitoring, geological structure research, and other areas of the low vibration level and low frequency vibration.
