Bently Nevada 330905-00-20-10-02-00 Proximity Extension Cable Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-00-20-10-02-00 is a high-quality proximity probe extension cable assembly designed for use within the 3300 XL 8 mm Proximity Transducer System. It is used to provide an extended electrical connection between a proximity probe installed near rotating machinery and the monitoring equipment responsible for vibration measurement, shaft displacement monitoring, and machinery protection.
The extension cable plays an important role in maintaining reliable signal transmission between the sensor and the monitoring system. It transfers the high-frequency eddy current measurement signal generated by the proximity probe while preserving signal accuracy and stability.
This model features a 20-meter cable length configuration, making it suitable for large industrial rotating equipment where the distance between the sensor installation location and monitoring cabinet requires additional cable length.
The 330905-00-20-10-02-00 is commonly applied in critical machinery systems such as steam turbines, gas turbines, compressors, generators, pumps, motors, and other high-value rotating equipment that require continuous condition monitoring.
The cable assembly is designed for industrial environments where long-term reliability is required. It can operate under conditions involving mechanical vibration, temperature variation, electromagnetic interference, oil exposure, and industrial contamination.
By providing stable signal transmission over a long distance, the product helps monitoring systems accurately detect shaft vibration, radial displacement, axial movement, and abnormal operating conditions, supporting safe and efficient machinery operation.

3. Product Series Information
3300 XL 8 mm Proximity Transducer System
The 330905-00-20-10-02-00 belongs to the 3300 XL 8 mm Proximity Transducer System series.
This series is designed for continuous monitoring of critical rotating machinery where precise measurement of shaft vibration, displacement, and rotor position is required.
The system uses eddy current sensing technology to achieve non-contact measurement between the proximity probe and rotating shaft.
Because the probe does not physically contact the rotating component, mechanical wear is avoided, allowing long service life and reliable measurement performance.
During operation, the proximity probe creates an electromagnetic field near the shaft surface.
When the shaft moves due to vibration, imbalance, thermal expansion, mechanical misalignment, or changing operating conditions, the distance between the probe tip and shaft surface changes.
This change modifies the electromagnetic field and generates a corresponding electrical signal.
The signal is transmitted through the extension cable to the monitoring equipment, where it is analyzed to determine machine operating conditions.
The 3300 XL 8 mm series provides:
- High measurement accuracy
- Excellent repeatability
- Stable signal transmission
- Long operational life
- Strong industrial environmental resistance
- Reliable machinery protection capability
The system structure includes:
| Component | Function |
|---|---|
| Proximity Probe | Measures shaft vibration and displacement |
| Extension Cable | Transfers sensor signals over required distance |
| Signal Processing Unit | Converts and processes electrical signals |
| Monitoring Module | Provides machine condition analysis |
| Protection System | Provides alarms and protective response |
The 330905-00-20-10-02-00 provides extended installation distance while maintaining measurement accuracy and signal stability.
4. Product Working Principle
The 330905-00-20-10-02-00 works as a signal transmission component in an eddy current proximity measurement system.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft.
When the shaft position changes, the gap between the probe tip and shaft surface changes accordingly.
These changes may result from:
- Rotor imbalance
- Shaft vibration
- Bearing wear
- Mechanical alignment problems
- Thermal expansion
- Load changes
The variation in distance changes the electromagnetic field strength around the probe.
The sensor converts this physical movement into an electrical measurement signal.
The extension cable transfers the signal from the proximity probe to the monitoring equipment while maintaining signal quality.
The monitoring system processes the signal and provides information about machine health.
The measurement data can be used for:
- Continuous vibration monitoring
- Shaft displacement analysis
- Rotor position monitoring
- Equipment protection
- Predictive maintenance planning
