The low-frequency accelerometer adopts a high-precision MEMS accelerometer and a dual-redundancy design scheme to ensure high system reliability.

The acceleration signal is filtered and output in real time via an analog signal. When the signal exceeds the threshold, a passive dry contact alarm signal is triggered, enabling vibration monitoring and safety protection for key components of wind turbine units, such as the transmission chain and tower tube.

Key features: High-precision 3-axis MEMS accelerometer with a resolution of 0.02mg. Dual-redundancy design for key components including MCU, MEMS, and SSD relay. Enhanced EMC (Electromagnetic Compatibility) protection design. Dual protection with software and hardware watchdogs. Fault snapshot data function for rapid fault localization.
