4. Working Principle
The probe operates by generating 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 interaction strength varies depending on the gap between probe and shaft.
This variation is converted into an electrical signal proportional to displacement, which is then used by monitoring systems for vibration analysis and equipment condition evaluation.
5. Application Fields
The model is widely used in rotating machinery condition monitoring systems across multiple industrial sectors.
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
- Heavy manufacturing rotating machinery
It is particularly important in predictive maintenance programs where early fault detection prevents costly equipment failure.
