Bently Nevada 330905-00-18-05-02-05 Proximity Extension Cable Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-00-18-05-02-05 is a high-precision proximity probe extension cable assembly designed for use with the 3300 XL 8 mm Proximity Transducer System. It is mainly used to extend the electrical connection distance between a proximity probe installed on rotating machinery and the monitoring equipment used for vibration analysis, shaft displacement measurement, and machine protection.
The extension cable is an essential connection component in a non-contact eddy current measurement system. It provides a reliable signal path between the proximity probe and monitoring equipment, allowing vibration and displacement signals to be transmitted accurately while maintaining stable electrical performance.
This model features an 18-meter cable length configuration, providing an extended installation capability for large industrial machines where the sensing point is located far away from the monitoring cabinet.
The 330905-00-18-05-02-05 is widely used in critical rotating equipment applications such as steam turbines, gas turbines, compressors, generators, pumps, motors, and other industrial machinery requiring continuous condition monitoring.
The product is designed for harsh industrial operating conditions. It can withstand long-term exposure to vibration, temperature changes, electromagnetic interference, oil contamination, and mechanical stress.
By ensuring reliable signal transmission, this extension cable helps monitoring systems accurately measure shaft vibration, radial displacement, axial movement, and abnormal operating conditions of rotating machinery.

3. Product Series Information
3300 XL 8 mm Proximity Transducer System
The 330905-00-18-05-02-05 belongs to the 3300 XL 8 mm Proximity Transducer System series.
This series is designed for continuous online monitoring of critical rotating machinery where accurate measurement of shaft vibration, displacement, and position is required.
The system adopts eddy current sensing technology, allowing non-contact measurement between the proximity probe and rotating shaft.
The non-contact design prevents mechanical wear between the sensor and machine shaft, providing stable operation and long service life.
During operation, the proximity probe generates an electromagnetic field around the shaft surface.
When the shaft position changes due to vibration, imbalance, thermal expansion, alignment problems, or mechanical conditions, the distance between the probe and shaft changes.
This distance variation generates a corresponding electrical signal, which is transmitted through the extension cable to the monitoring equipment.
The 3300 XL 8 mm system is widely applied because of:
- High measurement accuracy
- Excellent signal stability
- Long operating life
- Strong industrial environmental resistance
- Continuous monitoring capability
- Reliable equipment protection performance
The system components include:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement and vibration |
| Extension Cable | Transfers sensor signals over distance |
| Signal Processing Unit | Processes measurement signals |
| Monitoring Module | Provides condition monitoring information |
| Protection System | Provides alarms and protective functions |
The 330905-00-18-05-02-05 provides extended connection distance while maintaining signal quality and measurement reliability.
4. Product Working Principle
The 330905-00-18-05-02-05 operates as part of an eddy current proximity measurement system.
The proximity probe generates a high-frequency electromagnetic field near the rotating shaft.
When the shaft moves during operation, the distance between the shaft surface and the probe tip changes.
These movements may be caused by:
- Rotor imbalance
- Shaft vibration
- Mechanical misalignment
- Bearing wear
- Thermal expansion
- Load variation
The distance change modifies the electromagnetic characteristics of the sensor and creates a proportional electrical output signal.
The extension cable transfers this signal from the proximity probe to the monitoring equipment while maintaining signal integrity.
The monitoring system analyzes the signal and determines the operating condition of the rotating machine.
The collected information can be used for:
- Vibration monitoring
- Shaft displacement measurement
- Rotor position analysis
- Equipment protection
- Predictive maintenance
