High Sensitivity hyundai piezotronic accelerometer(IEPE) , industrial accelerator sensor for Vibration Measurement of Low Frequency and Low Vibration
The A25C 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, bridge structure testing, ground and foundation vibration monitoring, and geological structure research.
