Bently Nevada 330104‑00‑11‑05‑02‑00

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

1. Product Introduction

The 330104‑00‑11‑05‑02‑00 is a precision industrial proximity probe engineered for condition monitoring and protection of rotating machinery. It belongs to the 3300 XL 8 mm series, a legacy family of non‑contact eddy current probes widely adopted in power generation, petrochemical, heavy process, and industrial applications.

This proximity probe measures the relative position of a metallic target—usually a shaft—through changes in an electromagnetic field produced at the probe tip. Vibration, shaft displacement, and rotor motion are converted into voltage signals that feed into monitoring systems. These signals enable early detection of imbalance, misalignment, rubs, looseness, and other developing mechanical faults.

The designation “11” in the model number reflects a specific internal calibration and sensing configuration that can offer enhanced sensitivity or extended linear range compared with basic models. The trailing “05” indicates a 5 m standard industrial cable assembly with a fixed industrial connector. The “02‑00” suffix identifies classic connector/pin style for standard control room and monitoring hardware.

This product is designed to withstand harsh operating environments with high mechanical vibration, temperature extremes, airborne contaminants, and oil exposure. It is built for continuous use in mission‑critical monitoring systems.

3. Product Applications

The 330104‑00‑11‑05‑02‑00 probe is designed to serve as a core sensor in industrial machinery condition monitoring systems. It provides real‑time analog signals that allow engineers to assess the dynamic behavior of rotating equipment.

Typical application environments include:

• Steam and gas turbines in power generation plants

• High‑speed compressors in petrochemical and processing industries

• Large industrial pumps and fans

• Electric motors and generators

• Gearboxes and turbine trains

Functional monitoring tasks:

• Radial shaft vibration measurement for imbalance detection

• Minor displacement and orbit tracking

• Rotor dynamic analysis

• Insight into misalignment, looseness, and rub conditions

• Input for machinery protection logic (alarms/trips)

This sensor supports ongoing diagnostics and predictive maintenance by providing high‑resolution data that enhances the accuracy of trending algorithms and early fault detection.

4. Product Advantages

Enhanced measurement sensitivity:
The internal configuration (code “11”) provides greater sensitivity and improved stability over basic versions, suitable for more demanding vibration and displacement applications.

Non‑contact eddy current design:
Eliminates wear and minimizes the risk of mechanical interference between the probe and rotating parts.

Robust industrial construction:
Stainless steel housing and tip ensure long operational life in corrosive or contaminated environments.

Wide environmental tolerance:
Performs reliably under temperature variation, vibration, moisture, and airborne contaminants.

Standard cable configuration:
The 5 m cable length is optimal for machines where the sensor needs to be placed at a distance from the monitoring cabinet without signal loss.

High compatibility:
Designed to interface with industrial machine condition monitoring and protection systems seamlessly.
