Bently Nevada 330105-XX-XX-05-02-CN Full Technical Overview

1. Product Title

330105-XX-XX-05-02-CN 3300 XL 8 mm Reverse Mount Proximity Probe (CN Configuration)

2. Brand

This product belongs to a globally recognized industrial condition monitoring and machinery protection technology brand widely used for vibration monitoring, shaft displacement measurement, and predictive maintenance systems in power generation, oil & gas, petrochemical, metallurgy, and heavy industry.

3. Product Series

3300 XL 8 mm Proximity Transducer System (Reverse Mount Type)

This series is designed for high-precision non-contact measurement of shaft vibration and position in critical rotating machinery such as turbines, compressors, pumps, and generators.

4. Product Introduction

The 330105-XX-XX-05-02-CN is a configurable model within the 3300 XL 8 mm reverse mount proximity probe family.

It uses eddy current sensing technology, which enables precise measurement of distance changes between the probe tip and a conductive metallic shaft without physical contact.

The “05” segment in this model typically represents a short system length configuration (0.5 m class design), suitable for compact installations.

The “CN” suffix indicates a regional or compliance-oriented configuration, often used for China-market certification or project-specific requirement packaging.

This probe is designed as part of a full 3-component system:

• Proximity probe
• Extension cable
• Proximitor signal conditioner

Together, they provide continuous vibration and displacement monitoring for rotating machinery protection systems.

5. Technical Parameters

Key Specification Table

📌 Industry reference: similar 330105 configurations commonly weigh around 0.323 kg depending on cable length and termination style.

6. Product Applications

This probe is widely used in rotating machinery monitoring where compact installation and high reliability are required.

Main Applications:

• Steam turbine shaft vibration monitoring
• Gas turbine rotor displacement measurement
• Industrial compressor condition monitoring
• Pump cavitation and vibration detection
• Generator shaft vibration tracking
• Petrochemical rotating equipment
• Oil & gas pipeline compressors
• Power plant predictive maintenance systems

7. Product Advantages

1. Non-contact measurement

No physical contact with shaft, eliminating mechanical wear.

2. High installation flexibility

Short system configuration supports compact machine layouts.

3. High temperature resistance

Stable operation up to 177°C in harsh environments.

4. Strong signal stability

Designed for low-noise and high-accuracy signal output.

5. Industrial-grade durability

Stainless steel construction provides corrosion resistance.

6. Modular compatibility

Works with extension cables and proximitor modules.

7. 24/7 monitoring capability

Suitable for continuous machinery protection systems.

8. Working Principle

The probe operates based on the eddy current displacement principle:

• High-frequency electromagnetic field is generated
• Conductive shaft induces eddy currents
• Gap variation changes electromagnetic response
• Output voltage represents vibration/displacement

This allows accurate real-time monitoring of rotating machinery condition.

9. System Composition

A complete monitoring system includes:

• 8 mm reverse mount proximity probe (this model)
• Coaxial extension cable
• Proximitor signal conditioning module
