Product Overview

The Bently Nevada 3300/16-03-05-01-00-00-01 is a high-reliability, two-channel machinery protection module designed to monitor shaft radial vibration. This specialized component of the 3300 series system continuously processes signals from non-contacting proximity transducers to measure the dynamic motion of rotating shafts relative to their bearings. By providing real-time tracking of peak-to-peak displacement, the 3300/16 monitor acts as an essential safety layer for Turbine Supervisory Instrumentation (TSI). It is specifically engineered to detect mechanical faults such as rotor unbalance, shaft misalignment, and fluid-film instabilities before they escalate into catastrophic equipment failure.

Industrial Applications and Operational Use Cases

The 3300/16-03-05-01-00-00-01 is an industry-standard solution for the protection of high-speed rotating machinery in the energy, petrochemical, and manufacturing sectors.

• Steam and Gas Turbine Shafts Implementing X-Y orthogonal probe configurations to monitor shaft centerline position and orbital dynamics.

• Centrifugal Process Compressors Ensuring immediate machine trip protection during high-load vibration spikes or surge events.

• Critical Motor Drives Surveillance of large induction motors driving high-pressure pumps and industrial blowers.

• High-Speed Fans Monitoring radial vibration in cooling tower units and boiler draft fans to prevent structural fatigue.

• Hydro-Turbine Generators Tracking low-frequency vibration and shaft runout in vertical or horizontal water-driven units.

By leveraging the raw buffered outputs, maintenance personnel can perform in-depth spectral analysis using portable data collectors to identify specific fault frequencies, enabling a transition from reactive repairs to a data-driven predictive maintenance strategy.
