Bently Nevada 330905-00-12-05-02-05 Proximity Extension Cable Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-00-12-05-02-05 is a precision proximity probe extension cable assembly designed for use in the 3300 XL 8 mm Proximity Transducer System. It is mainly used to extend the electrical connection distance between a proximity probe installed near rotating machinery and the monitoring equipment responsible for signal processing and machine condition analysis.
The extension cable is an important part of an eddy current proximity measurement system. It provides a stable transmission path for vibration, displacement, and shaft position signals, ensuring that the monitoring system receives accurate information from critical rotating components.
The 330905-00-12-05-02-05 features a 12-meter cable length configuration, providing additional installation flexibility for large industrial equipment where the distance between the sensor location and the monitoring cabinet is considerable.
This model is widely used in applications requiring continuous machinery monitoring, including steam turbines, gas turbines, compressors, generators, pumps, and other high-value rotating equipment.
The cable assembly is designed for demanding industrial environments. It provides reliable performance under continuous vibration, temperature changes, electromagnetic interference, and mechanical stress conditions.
By maintaining stable signal transmission over long distances, the product helps monitoring systems accurately evaluate machine condition and support predictive maintenance activities.

3. Product Series Information
3300 XL 8 mm Proximity Transducer System
The Bently Nevada 330905-00-12-05-02-05 belongs to the 3300 XL 8 mm Proximity Transducer System series.
The 3300 XL 8 mm system is designed for continuous monitoring of rotating machinery where accurate measurement of shaft vibration, displacement, and rotor position is required.
The system uses eddy current sensing technology, which provides non-contact measurement between the sensor probe and the rotating shaft. This method avoids mechanical contact and provides excellent stability for long-term industrial operation.
The main advantages of this measurement technology include:
- High measurement accuracy
- Long service life
- No mechanical wear between probe and shaft
- Excellent repeatability
- Suitable for critical machinery protection
The complete monitoring system usually consists of:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft vibration and displacement |
| Extension Cable | Transfers signals between sensor and monitoring equipment |
| Signal Converter | Processes electrical measurement signals |
| Monitoring Module | Provides machine condition analysis |
| Protection System | Provides alarm and protection functions |
The 330905-00-12-05-02-05 serves as the connection link that transfers the measurement signal from the proximity probe to the monitoring system while maintaining signal accuracy.
4. Product Working Principle
The 330905-00-12-05-02-05 operates within an eddy current proximity measurement system.
The proximity probe generates an electromagnetic field near the rotating shaft surface.
When the shaft moves due to vibration, imbalance, thermal expansion, or mechanical changes, the distance between the probe tip and the shaft changes.
This distance variation changes the electrical characteristics of the sensor system and creates a corresponding measurement signal.
The extension cable transfers this signal from the probe to the monitoring equipment while maintaining signal stability and minimizing interference.
The monitoring system analyzes the received information to determine the condition of the rotating machine.
The measurement data can be used to monitor:
- Shaft vibration levels
- Rotor displacement
- Mechanical stability
- Alignment conditions
- Equipment operating status
