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 according to the distance between probe and shaft.
This variation is converted into an electrical signal proportional to displacement, which is then used by monitoring systems to analyze vibration, imbalance, and rotor condition.
5. Application Fields
The model is widely used in rotating machinery condition monitoring systems across multiple 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
- Heavy manufacturing rotating machinery
It is especially important in predictive maintenance programs where early fault detection reduces operational risk and downtime.
