Technical Specifications

Function and Working Principle

The 330780-51-05 sensor operates using eddy current proximity sensing technology, enabling accurate measurement of shaft vibration and displacement without physical contact.

Working principle:

• The probe generates a high-frequency electromagnetic field
• When a conductive target approaches, eddy currents are induced
• These changes affect the electromagnetic field
• The system converts this variation into a proportional electrical signal

This allows precise, real-time monitoring of rotating machinery conditions while eliminating mechanical wear.
