High-Performance Vibration Sensor Design

This paper proposes a high-performance vibration sensor design to address sensitivity and stability issues in existing sensors under wide frequency (0-1 kHz) and high-amplitude (>10 g) conditions. The ADXL317 accelerometer provides high-sensitivity three-axis acceleration measurement, while the AD2428W signal processing chip handles signal processing and data transmission. This combination ensures excellent sensitivity and stability across a wide frequency range and under large amplitude vibrations. Experimental results show that the sensor achieves a sensitivity of 80 mV/g to 85 mV/g in the 0-1 kHz range, with a maximum linearity deviation of 0.997% in the 1 g to 16 g acceleration range. This design offers an effective solution for precise measurements in challenging environments, suitable for industrial monitoring, equipment diagnostics, and applications in automotive and aerospace industries.
