Magnetoelectric Velocity Sensor
A magnetoelectric velocity sensor is designed for ultra-low-frequency vibration measurement, offering high resolution, a large dynamic range, and multi-gear sensitivity options with no need for zero adjustment. Its simple, reliable operation makes it ideal for detecting weak vibrations, pulsation responses of ground or structural systems, and ultra-low-frequency, large-amplitude motion in highly flexible structures. It is widely used in structural monitoring, industrial vibration assessment, and geophysical or civil engineering applications.
