4. Product Structure and Working Principle
The 330909-00-25-10-02-00 operates as part of a complete proximity monitoring system.
The typical system structure includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft vibration and displacement changes |
| Extension Cable | Transfers sensor signals to monitoring equipment |
| Signal Processing Unit | Converts and processes measurement signals |
| Monitoring Module | Provides machine protection and condition analysis |
The operating principle is based on eddy current measurement technology.
The proximity probe produces a high-frequency electromagnetic field near the rotating shaft surface. When the shaft moves because of vibration, thermal expansion, imbalance, or mechanical loading changes, the distance between the probe tip and shaft surface changes.
This distance variation changes the electromagnetic field and creates an electrical output signal representing shaft movement.
The extension cable transfers the measurement signal while maintaining:
- Signal accuracy
- Stable electrical characteristics
- Reduced transmission loss
- Improved interference resistance
The 10-meter cable length allows flexible installation for industrial machinery where the monitoring equipment is not located directly near the measurement point.
