製品紹介
The Bently Nevada 330505-02 Low Frequency Velocity Sensor is specifically designed for monitoring low-frequency vibrations in machinery, such as hydroelectric turbines, where slow rotating speeds require detecting low signal-to-noise ratios. It detects vibrations / the stator core, stator frame, and bearing housing supports, providing early warning / potential machinery problems and aiding in diagnostics before issues become serious.
