The Bently Nevada 350620 Low Frequency Velocity Transducer System (LFVTS) detects low-frequency and low-amplitude vibrations in slow-speed rotating machines, such as hydroelectric turbines. This system plays a critical role in monitoring machinery components like stator cores, stator frames, and bearing housings. Areas where early detection of vibration anomalies can help prevent significant operational damage. The LFVTS provides both shaft-relative and bearing-absolute vibration data, making it an essential diagnostic tool for predictive maintenance.
