Introduction

DiSens ECO-3321 MEMS capacitive 3-axis accelerometer combines high performance, robustness and reasonable cost. With measurement ranges from ±2 to ±40g, a frequency response of 1.5 kHz, and an IP67 waterproof housing with a shock limit of +/- 10.000g, DiSens ECO-3321 series is particularly well suited for vibration monitoring applications in severe conditions including automotive testing, railway testing civil engineering, wind power, and machine building.
