1. Product Title

330105-02-12-10-02-CN 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 predictive maintenance systems for rotating machinery.

3. Product Series

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

This series is widely used for continuous monitoring of critical rotating equipment such as turbines, compressors, pumps, and generators.

4. Product Introduction

The 330105-02-12-10-02-CN is an 8 mm reverse mount proximity probe designed for high-accuracy, non-contact measurement of shaft vibration and position.

It uses eddy current sensing technology, allowing it to detect small changes in distance between the probe tip and conductive metallic targets.

The “CN” suffix typically indicates a configuration with country-specific approvals or compliance requirements, making it suitable for certain regulated industrial installations while maintaining standard electrical and mechanical performance.

This probe is part of a complete measurement chain consisting of:

• Proximity probe
• Extension cable
• Signal conditioning module (proximitor sensor)

Together, these components provide reliable real-time monitoring for machinery protection systems.

7. Product Advantages

1. High Precision Non-Contact Measurement

Provides accurate and stable shaft vibration and displacement detection without physical contact.

2. Reverse Mount Design Flexibility

Ideal for installations where axial space or mounting direction is limited.

3. High Temperature Resistance

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

4. Strong Anti-Interference Capability

Excellent resistance to electromagnetic and radio frequency interference in industrial sites.

5. Durable Construction

Stainless steel housing and reinforced PPS probe tip ensure long service life.

6. Modular System Compatibility

Fully compatible with extension cables and signal conditioning modules.

7. Stable 24/7 Operation

Designed for continuous monitoring of critical equipment without performance degradation.

8. Working Principle

The probe operates based on the eddy current displacement principle:

• High-frequency electromagnetic field is emitted from the probe
• Conductive target surface (shaft) generates eddy currents
• Distance variation changes electromagnetic response
• Signal is converted into proportional voltage output

This enables accurate measurement of both vibration and shaft position in real time.

9. System Composition

A complete monitoring system includes:

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