Industrial Proximity Probe Technical Report (330105-02)
1. Product Overview
The model 330105-02 is an 8mm eddy current proximity probe designed for non-contact measurement of shaft vibration, radial displacement, and position in rotating machinery.
It is part of a standardized proximity transducer system used in industrial condition monitoring and protection systems.
This probe works together with a matching extension cable and proximitor sensor to form a complete measurement chain for real-time machinery health monitoring.
The configuration code “330105-02” generally indicates a specific probe build version within the 3300 XL 8mm probe architecture.
2. Brand Information
Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer
This product line is widely used in industrial vibration monitoring and predictive maintenance systems across power generation, oil & gas, petrochemical, metallurgy, and marine engineering.
3. Product Series
This model belongs to the 3300 XL 8mm Proximity Probe Series.
This series is designed for:
- High precision displacement measurement
- Long-term stability in harsh environments
- Compatibility with industrial monitoring systems
- Resistance to oil, dust, vibration, and high temperature conditions
It is widely adopted in API 670 compliant machinery protection systems.
4. Product Introduction
The probe operates using eddy current sensing technology.
A high-frequency electromagnetic field is generated at the probe tip. When a conductive metallic shaft moves within this field, eddy currents are induced on the surface.
These changes in the electromagnetic field are converted into a proportional voltage signal. This signal is used to measure:
- Shaft vibration amplitude
- Radial displacement
- Axial position
The system provides continuous, real-time monitoring for rotating equipment health analysis.
