Industrial Proximity Probe Technical Report (330105-02-12-05-02-RU)

1. Product Overview

The model 330105-02-12-05-02-RU is an 8mm eddy current proximity probe used for high-precision monitoring of shaft vibration, radial displacement, and axial position in rotating machinery systems.

It is a non-contact sensing device that continuously measures the gap between the probe tip and a conductive rotating shaft surface, enabling real-time condition monitoring and machinery protection.

The suffix “-RU” typically indicates a Russia-region or regional specification variant used for localized supply, documentation, or certification requirements within industrial distribution networks.

This probe is part of a modular proximity transducer system designed for continuous monitoring of critical rotating equipment.

2. Brand Information

Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer

This product line is widely used in:

• Power generation plants
• Oil and gas refineries
• Petrochemical facilities
• Marine propulsion systems
• Heavy industrial rotating machinery systems

3. Product Series

This model belongs to the 3300 XL 8mm Proximity Probe Series.

Key characteristics of this series include:

• High accuracy non-contact displacement measurement
• Long-term stability in harsh industrial environments
• Resistance to oil, dust, vibration, and high temperature
• Compatibility with standard vibration monitoring systems
• Use in API-style machinery protection architectures

The system typically consists of:

• Probe
• Extension cable
• Signal conditioning module (proximitor)

4. Product Introduction

The probe operates using eddy current electromagnetic induction technology.

A high-frequency electromagnetic field is generated at the probe tip. When a conductive shaft rotates within this field, eddy currents are induced on the shaft surface.

These variations in the electromagnetic field are converted into a proportional analog voltage signal.

This signal is used for:

• Shaft vibration measurement
• Radial displacement monitoring
• Axial position detection

It enables continuous real-time monitoring and predictive maintenance of rotating machinery.
