4. Product Structure and Working Principle
The 330909-00-80-70-02-00 works as an intermediate connection component in a complete proximity monitoring system.
A typical machinery monitoring system includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement, vibration, and displacement |
| Extension Cable | Transfers electrical measurement signals |
| Signal Conditioner | Processes sensor output signals |
| Monitoring Module | Provides machinery protection and diagnostic functions |
The product works based on eddy current measurement technology.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft.
When the shaft position changes due to mechanical conditions such as:
- Rotor imbalance
- Shaft bending
- Thermal expansion
- Coupling movement
- Bearing condition changes
the distance between the probe tip and shaft surface changes.
The changing distance modifies the electromagnetic field, producing a corresponding electrical signal.
The extension cable transfers this signal to the monitoring system while maintaining:
- Accurate signal transmission
- Stable electrical performance
- Low signal attenuation
- Reliable measurement quality
The cable design allows the monitoring equipment to be installed at a suitable location while keeping the sensor close to the rotating machinery.
