Overview
The 77581-02 Digital Vector Filter (DVF 3) is part of Bently Nevada’s third-generation DVF series, built to support complex vibration analysis in industrial environments. It captures dynamic signals from proximity probes, velocity transducers, and accelerometers, making it ideal for evaluating rotor behavior, detecting cracks, and performing balancing procedures.
Moreover, the module includes Keyphasor® input for accurate phase referencing, enabling engineers to generate Bodé plots, polar plots, sweep frequency plots, and vector displays. These capabilities are essential for diagnosing machinery faults and optimizing performance. For instance, in a gas turbine application, the DVF 3 helps identify resonance conditions and shaft instability before they escalate into critical failures.
In addition, the 77581-02 is CE-certified and designed for integration into Bently Nevada’s monitoring systems, including System 1 software. Its rugged construction and high-speed data handling make it suitable for demanding applications in power generation, petrochemical, and aerospace sectors.
