Bently Nevada 330905-05-10-10-02-05 Proximity Probe Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-05-10-10-02-05 is a high-performance 3300 XL 8 mm Proximity Probe designed for accurate measurement of shaft vibration, radial displacement, and relative shaft position in rotating machinery applications.
This model uses eddy current sensing technology, which provides non-contact measurement between the probe tip and the rotating shaft. The technology allows the system to continuously monitor small changes in shaft movement and convert them into electrical signals for machinery condition analysis.
The 330905-05-10-10-02-05 belongs to the 3300 XL 8 mm Proximity Probe Series. It is designed for industrial environments where reliability, measurement accuracy, and long operating life are essential.
The probe is commonly installed on critical rotating equipment such as steam turbines, gas turbines, compressors, generators, pumps, and large motors. It works together with compatible extension cables and signal processing modules to create a complete vibration monitoring and machinery protection system.
The 330905-05-10-10-02-05 configuration provides a practical solution for applications requiring stable shaft vibration measurement, compact installation, and reliable operation under continuous industrial conditions.

3. Product Structure and Working Principle
The 330905-05-10-10-02-05 proximity probe is composed of a sensing tip, stainless steel probe housing, threaded mounting section, internal sensing coil, and electrical connector.
The sensing tip generates an electromagnetic field toward the rotating shaft. When the shaft moves due to vibration or mechanical displacement, the gap between the probe and shaft surface changes.
The change in electromagnetic field strength is converted into an electrical signal that represents the actual shaft movement. The monitoring system then analyzes this information to determine machine operating conditions.
The complete measurement system normally includes:
- Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
The combination of these components provides continuous monitoring of rotating equipment performance.
The non-contact measurement design allows the probe to operate without physical wear, making it suitable for long-term industrial applications.
