4. Product Structure and Working Principle
The 330909-00-20-10-02-00 is used as part of a complete proximity measurement system.
The basic system structure includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft position, vibration, and displacement changes |
| Extension Cable | Transfers sensor signals over extended distance |
| Signal Processing Unit | Processes measurement signals |
| Monitoring System | Provides machinery condition analysis and protection |
The operating principle is based on eddy current measurement technology.
The proximity probe generates a high-frequency electromagnetic field around the rotating shaft surface. When the shaft moves due to vibration, thermal expansion, imbalance, or mechanical changes, the distance between the probe tip and shaft surface changes.
This distance variation affects the electromagnetic field and creates electrical signals corresponding to shaft movement.
The extension cable transfers these signals from the proximity probe to the monitoring system while maintaining:
- Signal accuracy
- Electrical stability
- Measurement consistency
- Low interference performance
The 10-meter cable length provides installation flexibility for large machinery installations where monitoring equipment is located away from the measurement point.
