4. Working Principle
The probe operates by generating a high-frequency electromagnetic field at the sensing tip.
When positioned near a conductive rotating shaft, eddy currents are induced on the shaft surface.
The coupling strength between probe and shaft varies according to the gap distance.
This variation is converted into an electrical signal proportional to displacement, which is then processed by monitoring systems for vibration analysis, imbalance detection, and rotor condition evaluation.
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
