4. Product Structure and Working Principle
The 330909-00-20-10-01-05 functions as a connection component within a complete proximity measurement system.
A standard system includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement and vibration changes |
| Extension Cable | Transfers sensor measurement signals |
| Signal Processing Module | Converts and processes sensor data |
| Monitoring System | Provides machine condition monitoring and protection |
The measurement principle is based on eddy current technology.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft surface. When the shaft position changes, the distance between the probe tip and shaft changes.
This variation affects the electromagnetic field and produces electrical signals proportional to the actual shaft movement.
The extension cable transfers these signals from the probe to the monitoring system while maintaining:
- Signal stability
- Measurement accuracy
- Electrical consistency
- Resistance to interference
The 10-meter cable length allows flexible installation for large industrial machines where sensors and monitoring cabinets are physically separated.
