Bently Nevada 350620 Low Frequency Velocity Transducer System

Product Introduction

The Bently Nevada 350620 Low Frequency Velocity Transducer System is an industrial-grade monitoring solution designed to measure low-frequency vibration velocity in rotating machinery and critical assets. This transducer system converts mechanical vibration into a proportional electrical signal, providing accurate, reliable, and continuous monitoring of machinery health.

The 350620 system is part of Bently Nevada’s proven machinery protection portfolio and is widely used for early detection of mechanical issues such as imbalance, misalignment, bearing looseness, and structural resonance. The system supports integration with Bently Nevada 3500 Series Monitoring Racks, enabling centralized machinery condition monitoring.

Its robust design ensures stable operation in harsh industrial environments, including high vibration, temperature extremes, and exposure to industrial contaminants. The low-frequency velocity transducer is ideal for monitoring large rotating machinery such as turbines, compressors, pumps, and generators, where precise vibration measurement is critical to predictive maintenance and operational safety.
