4. Product Structure and Working Principle
The 330909-00-28-10-02-RU works as an important connection component in a complete proximity monitoring system.
A typical system includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement, vibration, and displacement |
| Extension Cable | Transfers sensor signals over extended distance |
| Signal Processing Unit | Processes and converts measurement information |
| Monitoring Module | Provides machine protection and condition analysis |
The operating principle is based on eddy current measurement technology.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft surface. When the shaft position changes due to vibration, thermal expansion, imbalance, or mechanical movement, the distance between the probe and shaft changes.
This distance variation affects the electromagnetic field and generates an electrical signal proportional to shaft movement.
The extension cable transfers this signal from the probe to the monitoring equipment while maintaining:
- Stable signal transmission
- Accurate measurement performance
- Low electrical loss
- Improved resistance to external interference
The 10-meter cable length allows easier installation when sensors and monitoring cabinets are not located close together.
