4. Product Structure and Working Principle
The 330909-00-80-70-02-05 is a connection component used within a complete proximity monitoring system.
A typical system consists of:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement, vibration, and displacement |
| Extension Cable | Transfers measurement signals from sensor to monitoring unit |
| Signal Processing Equipment | Converts and processes sensor output |
| Monitoring Module | Provides alarm, protection, and condition analysis functions |
The product works together with an eddy current proximity probe system.
During operation, the proximity probe creates a high-frequency electromagnetic field near the rotating shaft.
When the shaft position changes due to mechanical conditions such as:
- Rotor imbalance
- Shaft movement
- Bearing wear
- Thermal expansion
- Coupling displacement
the distance between the probe tip and shaft surface changes.
The electromagnetic field changes accordingly, generating an electrical signal representing the shaft movement.
The extension cable transfers this signal while maintaining:
- Accurate signal transmission
- Stable electrical characteristics
- Reduced signal loss
- Reliable monitoring performance
The 10-meter cable length allows flexible installation between machinery and control systems while keeping measurement accuracy.
