Function and Working Principle
The probe operates using the eddy-current principle, where displacement is measured based on electromagnetic field interaction.
Operating Principle
- Probe generates a high-frequency electromagnetic field
- Eddy currents are induced in the conductive shaft surface
- Distance between probe and shaft changes signal response
- System converts signal into displacement and vibration data
x∝1Vx \propto \frac{1}{V}
Where displacement is inversely related to measured voltage response in the eddy-current system.
Key Functions
- Measures shaft vibration and radial displacement
- Provides real-time monitoring of rotating equipment health
- Detects early mechanical faults such as:
- Misalignment
- Imbalance
- Bearing wear
- Shaft instability
- Supports machine protection systems and condition monitoring platforms
Role in Industrial Systems
This probe is part of a 3-component measurement chain:
- Proximity probe (sensor head)
- Extension cable
- Proximitor sensor (signal conditioning unit)
Together, they form a complete eddy-current monitoring system used in:
- Critical rotating machinery protection
- Vibration analysis systems
- Predictive maintenance platforms
Industrial Applications
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Generators
- Industrial fans
- Petrochemical rotating equipment
- Power plant monitoring systems
Installation Guidelines
- Installed close to rotating shaft target surface
- Requires precise air-gap calibration
- Must maintain stable mounting to avoid signal drift
- Cable routing should minimize EMI exposure
- Ceramic tip must not be mechanically stressed during installation
⚠️ Incorrect installation can result in inaccurate vibration readings or system alarms.
