Bently Nevada 3300/16 Dual Vibration Monitor

The Bently Nevada 3300/16 is a dual-channel vibration monitor designed for the 3300 series rack system. It provides real-time radial vibration measurement and automated machinery protection for critical rotating assets. With independent alarm logic and 4-20 mA outputs, it integrates seamlessly into industrial control systems to enhance equipment reliability and prevent unscheduled downtime.

Product Overview

The Bently Nevada 3300/16 serves as a high-precision dual-channel monitoring module within the 3300 series machinery protection system. This instrument provides continuous, real-time oversight of radial vibration levels for rotating machinery. By processing signals from proximity transducer systems, the 3300/16 ensures that industrial assets operate within safe vibration limits. Consequently, the monitor facilitates early fault detection, such as unbalance, misalignment, or bearing instabilities, which significantly mitigates the risk of catastrophic mechanical failure.

Core Functionality and Operation

The 3300/16 module receives input from two independent vibration transducers, typically Eddy Current Proximity Probes. It converts these raw voltage signals into standardized engineering units, such as peak-to-peak displacement. Each channel is equipped with independent alarm logic, allowing operators to set “Alert” and “Danger” setpoints tailored to specific machine tolerances. Furthermore, the monitor includes sophisticated self-diagnostics that continuously verify the integrity of the transducer circuit and the internal hardware, preventing false trips caused by instrument failure.
