4. Product Structure and Working Principle
The 330909-00-20-10-02 is designed as part of a complete proximity measurement system.
A typical system consists of the following components:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement, vibration, and displacement |
| Extension Cable | Transfers electrical measurement signals |
| Signal Processing Module | Converts and processes measurement data |
| Monitoring System | Provides equipment condition analysis and protection |
The system operates based on eddy current measurement technology.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft. When the shaft moves, the distance between the probe tip and the shaft surface changes.
This change modifies the electromagnetic field, creating electrical signals proportional to the shaft movement.
The extension cable transfers these signals to the monitoring equipment while maintaining:
- Accurate signal transmission
- Stable electrical characteristics
- Low signal distortion
- Resistance to industrial interference
The 10-meter cable length allows installation in large machinery where the monitoring system cannot be positioned close to the sensor location.
