Product Overview

The Bently Nevada 3300/16-15-01-00-00-00-00 is a high-integrity, two-channel machinery protection module engineered for the precise measurement of radial shaft vibration. As a critical element of the legacy 3300 series, this monitor processes signals from non-contacting proximity transducers to track the dynamic motion of rotating shafts within their bearings. By providing real-time, hardware-based monitoring of peak-to-peak displacement, it serves as a fail-safe layer for Turbine Supervisory Instrumentation (TSI). This specific configuration is optimized for high-vibration environments, enabling the early detection of mechanical anomalies such as unbalance, shaft misalignment, and oil whirl to prevent catastrophic asset damage.
