Function and Working Principle
The 330780-50-CN sensor utilizes eddy current sensing technology to measure the distance between the probe and a conductive surface.
Working principle:
- The sensor emits a high-frequency electromagnetic field
- When a conductive object approaches, eddy currents are generated
- These currents influence the sensor’s electromagnetic field
- The variation is converted into an electrical signal proportional to displacement
This process enables precise, real-time monitoring without physical contact, ensuring long-term reliability and measurement accuracy.
