4. Working Principle
The probe generates a high-frequency electromagnetic field at its sensing tip.
When positioned close to a conductive rotating shaft, eddy currents are induced on the shaft surface.
The interaction strength varies depending on the distance between probe and shaft.
This variation is converted into an electrical signal proportional to displacement, which is then interpreted by monitoring systems to assess vibration behavior and mechanical condition.
5. Application Fields
The model is widely used in rotating machinery 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:
