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.
