1. Product Title

330105-02-12-05-02-00 3300 XL 8 mm Reverse Mount Proximity Probe

2. Brand

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

3. Product Series

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

This series is widely used in high-value rotating machinery where accurate vibration and position monitoring is required for safety and predictive maintenance.

4. Product Introduction

The 330105-02-12-05-02-00 is an 8 mm reverse mount proximity probe designed for high-precision non-contact measurement of shaft vibration and axial displacement.

It uses eddy current sensing technology, which allows it to measure the distance between the probe tip and conductive target surfaces without physical contact.

This model is designed for installation environments where space constraints or mounting limitations require a reverse configuration.

It is typically used as part of a complete system that includes:

• Proximity probe (this model)
• Extension cable
• Signal conditioning module (proximitor)

Together, these components provide stable and accurate vibration data for industrial monitoring systems.

7. Product Advantages

1. High Precision Non-Contact Measurement

Ensures accurate detection of shaft vibration without physical wear.

2. Reverse Mount Flexibility

Ideal for tight or restricted installation spaces.

3. Strong Environmental Resistance

Stable operation under high temperature and harsh industrial conditions.

4. Long Service Life

No mechanical contact means minimal degradation over time.

5. Stable Signal Output

Designed for low noise and high stability in industrial environments.

6. Modular Compatibility

Works seamlessly with extension cables and signal processors in the same system.

7. Industrial Reliability

Suitable for continuous 24/7 monitoring of critical equipment.

8. Working Principle

The probe operates using the eddy current displacement principle:

• The probe generates a high-frequency electromagnetic field
• Conductive target surfaces (shaft) induce eddy currents
• Distance changes alter the electromagnetic response
• The system converts this into voltage signals representing vibration or displacement

This allows accurate real-time monitoring of machinery behavior.

9. System Composition

A complete monitoring setup includes:

• 8 mm reverse mount proximity probe (this model)
• Extension cable (matched impedance coaxial cable)
• Proximitor sensor (signal conditioning unit)
