Function and Working Principle
The probe operates using the eddy-current principle, where changes in distance between the probe tip and a conductive target (shaft) are converted into electrical signals.
Operating Principle
- Probe generates a high-frequency electromagnetic field
- Eddy currents are induced in the shaft surface
- Distance variation changes signal response
- Output voltage represents displacement and vibration
x∝Vx \propto V
Where displacement (x) is proportional to the conditioned output voltage (V).
Key Functions
- Measures shaft vibration and radial displacement
- Provides real-time monitoring of rotating machinery condition
- Detects early mechanical issues such as:
- Imbalance
- Misalignment
- Bearing wear
- Shaft instability
- Supports machine protection and shutdown systems
System Role
This probe is part of a complete 3300 XL proximity measurement chain:
- Proximity probe (sensor head)
- Extension cable
- Proximitor sensor (signal conditioning module)
Together, they form a calibrated system used for:
- Vibration monitoring
- Shaft position measurement
- Machinery protection inputs
Industrial Applications
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Generators
- Industrial fans
- Petrochemical rotating machinery
- Power generation systems
Installation Guidelines
- Installed close to rotating shaft surface
- Requires precise air-gap calibration
- Must maintain rigid mechanical alignment
- Cable routing should avoid EMI sources
- Proper shielding and grounding required
- Must be calibrated as part of complete system configuration
⚠️ Incorrect installation or mismatched system components can lead to inaccurate readings.
