Bently Nevada 330105-XX-XX-10-02-00 + MOD 157310-04 Full Technical Overview

1. Product Title

330105-XX-XX-10-02-00 MOD 157310-04 3300 XL 8 mm Reverse Mount Proximity Probe

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 sectors.

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-10-02-00 MOD 157310-04 is a modified configuration of the 3300 XL 8 mm reverse mount proximity probe system.

It uses eddy current sensing technology, allowing accurate measurement of shaft displacement and vibration without physical contact.

The “10” configuration typically indicates a 1.0 m system length class, suitable for compact-to-medium industrial installations where probe-to-proximitor distance is moderate.

The “MOD 157310-04” suffix indicates a factory-modified or project-specific variant, often used for OEM customization, retrofit replacement, or application-specific compliance requirements.

This probe is part of a complete system consisting of:

• Proximity probe
• Extension cable
• Proximitor signal conditioner

Together, they form a continuous vibration monitoring chain for rotating machinery protection and predictive maintenance.

5. Technical Parameters

Key Specification Table

📌 Reference data confirms 3300 XL 8 mm probes typically fall in this weight range depending on cable and modification configuration.

📌 Shipping packaging for modified variants may reach ~2 kg depending on kit form (probe + accessories).

6. Product Applications

This probe is widely used in rotating machinery condition monitoring systems.

Main Applications:

• Steam turbine shaft vibration monitoring
• Gas turbine rotor displacement measurement
• Compressor vibration and stability monitoring
• Industrial pump condition monitoring
• Generator shaft vibration tracking
• Petrochemical rotating machinery systems
• Oil & gas pipeline compressors
• Power plant predictive maintenance systems

7. Product Advantages

1. Non-contact measurement

No physical wear, enabling long-term stable operation.

2. Factory-modified configuration

MOD version supports project-specific installation requirements.

3. High reliability in harsh environments

Designed for industrial vibration, heat, and oil exposure conditions.

4. Strong signal stability

Low-noise output suitable for precision monitoring.

8. Working Principle

The system uses the eddy current displacement principle:

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

This enables real-time monitoring of rotor behavior.

9. System Composition

A complete system includes:

• 8 mm reverse mount probe (modified version)
• Extension cable
• Proximitor signal conditioning module
