Function and Working Principle
The 330780-91-05 sensor operates using eddy current proximity sensing technology to measure the distance between the probe tip and a conductive target surface without physical contact.
Working principle:
- The probe generates a high-frequency electromagnetic field
- When a conductive target approaches, eddy currents are induced
- These eddy currents modify the electromagnetic field
- The system converts these variations into proportional electrical signals
This enables precise real-time measurement of vibration and shaft displacement while eliminating mechanical wear and ensuring long-term stability.
