Working principle of SZ-6 magneto electric vibration velocity sensor

The SZ-6 magneto electric velocity sensor is an inertial sensor that uses the principle of magneto electric induction to convert vibration signals into voltage signals, which are proportional to the vibration velocity value. It can be used to measure the vibration of bearing bases, or casings or structures (relative to inertial space vibration). It is directly installed outside the machine, making it extremely convenient to use and maintain.
