Bently Nevada 330905-02-10-05-02-CN Proximity Probe Product Detailed Description
1. Product Introduction
The Bently Nevada 330905-02-10-05-02-CN is a 3300 XL 8 mm Proximity Probe designed for high-precision monitoring of rotating machinery. It is mainly used for measuring shaft vibration, radial displacement, axial movement, and relative shaft position in critical industrial equipment.
This model is based on eddy current sensing technology. By generating an electromagnetic field between the probe tip and the rotating shaft surface, the system can accurately detect changes in shaft position without physical contact. The measured signal is transmitted to the monitoring system through a compatible Proximitor Sensor and used for machinery condition analysis and protection.
The 330905-02-10-05-02-CN belongs to the 3300 XL 8 mm Proximity Probe Series. The CN suffix indicates a special configuration identification, commonly associated with regional or customer-specific ordering requirements while maintaining the standard 3300 XL product structure and performance characteristics.
The probe is designed for applications where high accuracy, long-term stability, and reliable operation are required. It is widely used on turbines, compressors, generators, pumps, and other large rotating machines where early detection of mechanical problems is essential.

3. Product Structure and Operating Principle
The 330905-02-10-05-02-CN proximity probe consists of a sensing tip, probe body, threaded mounting section, internal coil, and electrical connector.
The sensing tip produces a high-frequency electromagnetic field toward the rotating shaft. When the distance between the probe and shaft changes, the electromagnetic field changes accordingly. These variations are converted into electrical signals that represent shaft displacement.
The measurement process does not require direct contact with the rotating component. This allows the probe to operate continuously without mechanical wear caused by friction.
The complete monitoring system usually consists of:
- Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
Together, these components provide continuous information about machinery operating conditions.
