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

1. Product Title

330105-02-12-10-05-05 3300 XL 8 mm Reverse Mount Proximity Probe

2. Brand

This product belongs to a globally recognized industrial condition monitoring technology brand widely used in vibration monitoring, shaft displacement measurement, and rotating machinery protection systems.

3. Product Series

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

This series is designed for high-accuracy, non-contact measurement of shaft vibration and position in critical rotating equipment.

4. Product Introduction

The 330105-02-12-10-05-05 is an 8 mm reverse mount proximity probe used for precise measurement of shaft vibration and axial displacement in industrial machinery.

It works based on eddy current measurement technology, allowing accurate detection of small distance changes between the probe tip and conductive metal targets such as rotating shafts.

The reverse mount structure is designed for installations where space is limited or where conventional axial mounting is not suitable.

This model is typically used as part of a full monitoring chain including:

• Proximity probe
• Extension cable
• Proximitor signal conditioning unit

The system delivers stable real-time signals used in machinery protection and predictive maintenance systems.

Key Specification Table

Note: This specific variant closely matches standard 330105-02-12-10-02-05 series specifications where weight and geometry remain consistent across most assembly options.

6. Product Applications

This probe is widely used in industrial rotating machinery where continuous monitoring is critical.

Main Applications:

• Steam turbine vibration monitoring
• Gas turbine rotor displacement measurement
• Centrifugal compressor condition monitoring
• Industrial pump shaft vibration detection
• Motor bearing health monitoring
• Oil & gas rotating equipment systems
• Petrochemical process machinery
• Power generation monitoring systems

7. Product Advantages

1. High-Accuracy Non-Contact Measurement

Ensures stable vibration and displacement detection without physical wear.

2. Reverse Mount Flexibility

Ideal for compact or restricted installation environments.

3. High Temperature Stability

Reliable operation up to 177°C in harsh industrial environments.

4. Strong Signal Stability

Low noise output even in high electromagnetic interference areas.

5. Durable Mechanical Structure

Stainless steel housing ensures long service life.

6. Modular System Compatibility

Works seamlessly with matched cables and proximitor modules.

7. Industrial Reliability

Designed for continuous 24/7 monitoring of critical machinery.

8. Working Principle

The probe operates using the eddy current displacement principle:

• A high-frequency electromagnetic field is generated
• Conductive target (shaft) induces eddy currents
• Distance changes modify electromagnetic response
• Output is converted into proportional voltage signal

This enables precise real-time vibration and position measurement.

9. System Composition

A complete monitoring system includes:

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