Bently Nevada 330104‑00‑10‑10‑02‑CN

Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)

1. Product Introduction

The 330104‑00‑10‑10‑02‑CN is an industrial eddy‑current proximity probe crafted for precise, non‑contact monitoring of rotating machinery vibration and shaft displacement. It belongs to the 3300 XL 8 mm series, a widely adopted line of sensors used in condition monitoring and machine protection systems across a variety of heavy industrial sectors.

This probe detects changes in distance between its sensing tip and a conductive surface, typically a spinning shaft or rotating component. The eddy current effect induces a predictable electrical signal that corresponds to the gap between the probe tip and target surface. This continuous analog signal feeds into monitoring hardware to provide real‑time condition feedback for vibration analysis, rotor displacement assessment, and fault trend detection.

The model code reflects several configuration elements: “10” indicates a measurement range suitable for applications needing up to 10 mm of displacement detection, “02” signifies a standard industrial connector configuration, and “CN” denotes a specific connector or cable preparation suited for standard industrial environments. The probe is designed for long‑term reliability, stable measurement performance, and resistance to harsh elements encountered in industrial applications.

3. Product Applications

The 330104‑00‑10‑10‑02‑CN proximity probe is intended for continuous condition monitoring in industrial environments where rotating machinery health is critical to plant reliability and safety. It provides real‑time data to detect deviations from normal operating behavior, enabling early fault detection and predictive maintenance planning.

Typical applications include:

• Steam turbines and gas turbines in power generation

• Industrial compressors (centrifugal, screw, and positive displacement)

• Large pumps in chemical, water treatment, and oil refining

• Electric motors and generators with high rotational speeds

• Gearboxes, couplings, and drive trains

Key monitoring functions:

• Radial vibration measurement to detect imbalance, looseness, and resonance

• Radial shaft displacement for rotor position tracking

• Rotor dynamic analysis for identifying misalignment and rubbing conditions

• Support for machinery protection trip logic

• Trend data for predictive maintenance and fault forecasting

In all cases, the proximity probe contributes critical analog information that condition monitoring systems use for alarms, trend displays, spectral analysis, and safety responses.
