4. Product Structure and Working Principle
The 330909-00-20-10-02-05 works as an important connection component in a complete proximity monitoring system.
The system normally consists of:
| Component | Function |
|---|---|
| Proximity Probe | Measures shaft vibration and displacement changes |
| Extension Cable | Transfers measurement signals from the sensor |
| Signal Processing Unit | Processes and converts sensor 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 moves because of vibration, thermal expansion, imbalance, or mechanical changes, the distance between the probe tip and shaft changes.
This distance change modifies the electromagnetic field and produces an electrical signal proportional to shaft movement.
The extension cable transfers this signal to the monitoring equipment while maintaining:
- Stable signal transmission
- Accurate measurement results
- Reduced signal loss
- Improved resistance to interference
The 10-meter length allows installation flexibility for large industrial equipment where the sensor location is far from the monitoring cabinet.
