Overview

The Bently Nevada 3300/16-12-01-02-01-02-00 Dual Vibration Monitor is a key component of the 3300 series machinery protection platform, developed for continuous radial vibration and shaft position monitoring on high-value rotating assets such as steam turbines, compressors, pumps, and motors.

This unit accepts inputs from two Proximitor® systems, enabling independent X/Y channel monitoring or dual radial measurements on a single shaft. Compared to the older 3300/15 Radial Vibration Monitor, this model enhances capability with dedicated gap (position) measurement, improving diagnostic coverage and fault detection accuracy.

In addition, hermetically sealed relay outputs and CSA / NRTL / C approvals ensure electrical robustness in severe industrial environments. For example, within a petrochemical compressor train, this monitor enables early intervention for shaft rubbing, bearing distress, or misalignment before they escalate into major equipment failures.

Technical Data

Typical Applications

• Turbines & Compressors — Continuous radial vibration + shaft centerline tracking

• Industrial Motors & Pumps — Early detection of imbalance or misalignment

• Refining & Petrochemical Plants — API 670-compliant critical machine protection

• Power Generation — Enhanced reliability of rotating assets

• OEM Equipment — Embedded monitoring for high-availability machines

The 3300/16 series is widely deployed by reliability and protection engineers who require proven accuracy, durability, and seamless integration into legacy 3300 monitoring infrastructures.
