Industrial Technical Report
Proximity Probe Model: 330901-00-24-05-02-CN
1. Product Overview
The model 330901-00-24-05-02-CN is a high-precision non-contact proximity probe used for measuring shaft vibration, axial displacement, and position changes in rotating machinery systems.
It is designed for continuous industrial condition monitoring where stability, accuracy, and long-term reliability are required under harsh operating environments.
This probe is part of a widely used eddy-current based sensing architecture and is typically integrated into a three-component measurement chain (probe + extension cable + signal conditioning module).

4. Product Introduction
This probe operates using the eddy current principle, where a high-frequency electromagnetic field is generated at the probe tip.
When the probe approaches a conductive surface, changes in the distance alter the eddy current strength, which is converted into an electrical signal proportional to displacement.
The system is designed for continuous monitoring rather than intermittent measurement, making it suitable for critical rotating equipment protection.
The “CN” suffix typically indicates a regional or configuration-specific version tailored for localized industrial deployment requirements.
5. Product Applications
This model is widely used in rotating machinery condition monitoring systems, including:
- Steam turbine rotor systems
- Gas turbine assemblies
- Centrifugal compressors
