Description

Brief Product Description

The Bently Nevada 3300/16 is a high-reliability dual-channel vibration monitor designed to provide continuous machinery protection by measuring radial vibration.¹ This module processes signals from proximity transducers to deliver real-time diagnostics and automatic shutdown capabilities for critical industrial assets.

​Product Description

The Bently Nevada 3300/16 serves as a fundamental component of the 3300 Monitoring System, specifically engineered to provide two independent channels of radial vibration monitoring. This module accepts inputs from proximity transducer systems—most commonly the 3300 XL 8mm series—to measure shaft motion relative to the bearing housing.² By providing high-precision monitoring of vibration amplitudes, the 3300/16 enables plant operators to identify mechanical instabilities such as unbalance, misalignment, or bearing clearance issues before they lead to catastrophic equipment failure.³

Reliable Machinery Protection and Fault Detection

This dual-channel monitor prioritizes asset safety through its integrated alarm and danger relay logic. The 3300/16 continuously compares incoming vibration signals against user-defined setpoints, triggering visual alerts and relay outputs when vibration levels exceed safe thresholds. Furthermore, the module features advanced signal processing that filters out noise and transient interference, ensuring that only genuine mechanical faults activate protection sequences. Because it provides “OK” circuit monitoring, the system can distinguish between a transducer malfunction and an actual machinery vibration event, thereby preventing false trips.

Industrial Integration and Versatility

The 3300/16 is built for seamless integration into Turbine System Instrumentation (TSI) racks and broader Distributed Control Systems (DCS). It provides proportional 4-20 mA outputs for each channel, allowing for easy data logging and trend analysis in remote control rooms.⁴ Although the 3500 series has largely succeeded the 3300 range, the 3300/16 remains an essential spare part for maintaining legacy installations in power plants, refineries, and manufacturing facilities worldwide. Its rugged design and proven field performance ensure long-term stability in the harshest industrial environments.
