Industrial Technical Report
Proximity Probe Model: 330901-00-32-05-00-CN
1. Product Overview
The model 330901-00-32-05-00-CN is a non-contact proximity probe designed for high-precision measurement of shaft vibration, axial displacement, and rotor position in rotating machinery systems.
It is widely applied in continuous monitoring environments where long-term stability, signal accuracy, and resistance to harsh industrial conditions are required.
This probe operates as part of an eddy current-based displacement measurement system and is typically paired with extension cables and signal conditioning modules to form a complete monitoring chain.

5. Product Introduction
This probe works based on the eddy current principle. A high-frequency electromagnetic field is generated at the probe tip, and when a conductive target approaches, eddy currents are induced on the surface.
The variation in these currents is converted into a proportional electrical signal representing distance changes.
The system is designed for continuous real-time monitoring, making it suitable for critical machinery protection rather than occasional measurement.
The “CN” suffix generally indicates a region-specific configuration or packaging variation adapted for localized industrial deployment requirements.

This model is widely used in industrial rotating equipment monitoring systems, including:
- Steam turbine rotor assemblies
- Gas turbine systems
- Centrifugal compressors
