4. Working Principle
The probe generates a high-frequency electromagnetic field at its sensing tip.
When placed near a conductive rotating shaft, eddy currents are induced on the shaft surface.
The coupling between probe and shaft varies depending on the gap distance.
This variation is converted into an electrical signal proportional to displacement, which is then used by monitoring systems for vibration analysis, imbalance detection, and rotor condition assessment.
5. Application Fields
The model is widely used in rotating machinery condition monitoring systems across heavy industries.
It is applied for measuring shaft vibration, rotor eccentricity, axial position, and dynamic clearance in real time.
Typical application industries include:
- Gas turbine and steam turbine power plants
- Hydroelectric generation systems
- Oil and gas compressor stations
- Petrochemical refining facilities
- Industrial pumping systems
- Marine propulsion systems
