3. Product Series Information
3300 XL 8 mm Proximity Transducer System
The 330905-00-12-05-02-RU belongs to the 3300 XL 8 mm Proximity Transducer System series.
The 3300 XL 8 mm series is designed for monitoring the operating condition of high-value rotating machinery. It provides accurate measurement of shaft vibration, displacement, and rotor position through eddy current sensing technology.
The system uses a non-contact measurement principle. The proximity probe generates an electromagnetic field near the rotating shaft surface. When the shaft moves, the distance between the probe tip and shaft changes, creating a corresponding electrical signal.
The monitoring system analyzes these signals to determine the condition of the machinery.
The 3300 XL 8 mm system is widely used because of the following characteristics:
- High measurement accuracy
- Excellent repeatability
- Continuous monitoring capability
- Long operating life
- Strong resistance to industrial environments
- Suitable for machinery protection applications
The main system components include:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement and vibration changes |
| Extension Cable | Transfers signals from the probe to monitoring equipment |
| Signal Processing Unit | Converts and processes sensor output |
| Monitoring Module | Provides vibration analysis and alarm functions |
| Protection System | Supports equipment safety monitoring |
The 330905-00-12-05-02-RU acts as the signal connection component between the sensor and monitoring equipment, ensuring accurate transmission of measurement information.
4. Product Working Principle
The 330905-00-12-05-02-RU operates as part of an eddy current proximity measurement system.
During operation, the proximity probe produces a high-frequency electromagnetic field near the rotating shaft.
When the shaft moves due to vibration, imbalance, thermal expansion, or mechanical changes, the distance between the shaft and probe changes.
This change affects the electromagnetic field and generates a proportional electrical measurement signal.
The extension cable transfers this signal from the probe to the monitoring electronics while maintaining signal quality and reducing external interference.
The monitoring equipment processes the signal and provides information about machine operating conditions.
The measured information can be used for:
- Vibration monitoring
- Rotor position measurement
- Shaft displacement analysis
- Equipment protection
- Predictive maintenance planning
