Bently Nevada 330905-00-17-50-02-CN Proximity Extension Cable Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-00-17-50-02-CN is a high-performance proximity probe extension cable assembly designed for use with the 3300 XL 8 mm Proximity Transducer System. It is used to extend the electrical connection distance between a proximity probe installed on rotating machinery and the monitoring equipment responsible for vibration measurement, displacement monitoring, and machinery protection.
The extension cable provides a stable transmission path for the high-frequency signal generated by the proximity probe. It ensures that vibration and position information can be transferred accurately from the sensing location to the monitoring system while maintaining signal quality and measurement reliability.
This model is configured with a 17.5-meter cable length, providing an extended installation distance suitable for large industrial machines where the sensor location and monitoring cabinet are installed far apart.
The 330905-00-17-50-02-CN is commonly used in critical rotating machinery applications, including steam turbines, gas turbines, compressors, generators, pumps, motors, and other industrial equipment requiring continuous condition monitoring.
The cable assembly is designed for demanding industrial environments. It provides reliable performance under conditions such as continuous mechanical vibration, temperature variation, electromagnetic interference, oil contamination, and long-term operation.
By maintaining accurate signal transmission between the proximity probe and monitoring equipment, this product helps ensure reliable measurement of shaft vibration, radial displacement, axial movement, and machine operating condition.

3. Product Series Information
3300 XL 8 mm Proximity Transducer System
The 330905-00-17-50-02-CN belongs to the 3300 XL 8 mm Proximity Transducer System series.
This product series is designed for continuous monitoring of critical rotating machinery where accurate measurement of shaft vibration, displacement, and rotor position is required.
The system uses eddy current sensing technology to perform non-contact measurement between the proximity probe and rotating shaft.
Because the sensing process does not require physical contact, the system avoids mechanical wear and provides stable long-term operation.
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 shaft changes.
This distance variation creates an electrical signal that represents the shaft movement.
The signal is transmitted through the extension cable to monitoring equipment where it is analyzed for machine condition evaluation.
The 3300 XL 8 mm series provides:
- High measurement accuracy
- Excellent repeatability
- Stable signal transmission
- Long operating life
- Strong resistance to industrial environments
- Continuous machinery protection capability
The main components of the system include:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft vibration and displacement |
| Extension Cable | Extends the electrical connection distance |
| Signal Processing Unit | Converts and processes sensor signals |
| Monitoring Module | Displays and analyzes machine condition |
| Protection System | Provides alarm and shutdown functions |
The 330905-00-17-50-02-CN provides extended installation capability while maintaining reliable signal transmission.
4. Product Working Principle
The 330905-00-17-50-02-CN operates as a connection component in an eddy current proximity measurement system.
The proximity probe creates a high-frequency electromagnetic field near the rotating shaft.
When the shaft moves, the distance between the shaft surface and the probe tip changes.
These changes may be caused by:
- Rotor imbalance
- Shaft vibration
- Mechanical misalignment
- Bearing condition changes
- Thermal expansion
- Operating load changes
The distance variation changes the characteristics of the electromagnetic field.
The sensor converts this change into an electrical measurement signal.
The extension cable transfers this signal to the monitoring equipment while maintaining signal integrity.
The monitoring system processes the signal and evaluates machine operating conditions.
The measured information can be used for:
- Vibration trend analysis
- Rotor displacement monitoring
- Shaft position measurement
- Machine protection
- Predictive maintenance
