Function and Working Principle
The 330780-50-05 sensor operates using eddy current sensing technology to measure the distance between the probe tip and a conductive target surface.
Working process:
- The probe generates a high-frequency electromagnetic field
- When placed near a metal surface, eddy currents are induced
- These currents affect the electromagnetic field
- The system converts this variation into an electrical signal
This enables accurate, real-time monitoring of vibration and shaft displacement without physical contact.
