4. Product Introduction
This probe operates based on the eddy current principle. A high-frequency electromagnetic field is generated at the probe tip. When the probe approaches a conductive metal surface, eddy currents are induced, and the resulting signal variation is converted into a proportional displacement output.
The system is designed for continuous real-time monitoring rather than intermittent measurement, making it suitable for critical machinery protection systems.
The configuration suffix “CN” typically indicates a region-specific or application-specific version used in industrial deployment environments.
5. Application Areas
This model is widely used in rotating machinery condition monitoring systems across multiple industries:
- Steam turbine generator sets
- Gas turbine systems
- Centrifugal compressors
- Industrial pump systems
- Gearbox vibration monitoring
- Petrochemical processing equipment
- Marine propulsion systems
