5. Product Structure and Working Principle
The 330904-00-02-10-02-00 consists of a sensing probe tip, protective housing, integrated cable assembly, and electrical connection interface.
The product operates using eddy current sensing technology.
When the probe is powered, it generates a high-frequency electromagnetic field near the rotating shaft. When the shaft moves relative to the probe, the gap distance changes.
This change affects the electromagnetic field strength, and the probe converts the variation into an electrical signal proportional to shaft displacement.
The monitoring system receives and processes the signal to evaluate machine operating conditions.
The non-contact measurement design provides:
- No physical contact with rotating components.
- Reduced mechanical wear.
- Stable measurement during high-speed operation.
- Improved reliability.
- Long operating life.
