Bently Nevada 330105-05-12-10-02-00 Full Technical Overview

1. Product Title

330105-05-12-10-02-00 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 in vibration monitoring, shaft displacement measurement, and predictive maintenance systems across power generation, oil & gas, petrochemical, and heavy industry sectors.

3. Product Series

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

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

4. Product Introduction

The 330105-05-12-10-02-00 is an 8 mm reverse mount proximity probe designed for continuous monitoring of rotating machinery condition.

It uses eddy current sensing technology, enabling accurate measurement of the distance between the probe tip and conductive metal shaft surfaces without physical contact.

The “05” configuration typically corresponds to a short system length (about 0.5 m class configuration), commonly used in compact machinery or short routing installations where probe-to-proximitor distance is minimal.

The reverse mount structure makes it suitable for installations where axial space is limited or where conventional probe orientation cannot be used.

This probe is part of a complete 3-component system:

• Proximity probe
• Extension cable
• Proximitor signal conditioning module

Together, they form a stable vibration monitoring chain for machinery protection and predictive maintenance systems.

5. Technical Parameters

Key Specification Table

📌 Reference industry data shows similar 330105 probes typically weigh around 0.323 kg depending on configuration and cable length.

6. Product Applications

This probe is widely used in industrial rotating machinery where compact installation and reliable vibration monitoring are required.

Main Applications:

• Steam turbine shaft vibration monitoring
• Gas turbine rotor displacement measurement
• Industrial compressor monitoring systems
• Pump vibration analysis
• Motor bearing condition monitoring
• Generator shaft vibration tracking
• Petrochemical rotating equipment
• Power plant predictive maintenance systems

7. Product Advantages

1. Compact installation design

Short system length supports tight machinery layouts.

2. Non-contact measurement

No mechanical wear, ensuring long-term stability.

3. High temperature resistance

Stable operation up to 177°C in harsh environments.

8. Working Principle

The probe operates using the eddy current displacement principle:

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

This enables precise real-time monitoring of rotating machinery condition.
