Bently Nevada 330905-08-13-10-12-05 Proximity Probe Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-08-13-10-12-05 is a high-precision 3300 XL 8 mm Proximity Probe designed for continuous monitoring of rotating machinery operating conditions. It is mainly used to measure shaft vibration, radial displacement, axial position movement, and relative shaft motion in industrial rotating equipment.
This model uses eddy current sensing technology, providing accurate non-contact measurement between the probe tip and the rotating shaft surface. The sensing element detects changes in the distance between the probe and the shaft, converts these mechanical movements into electrical signals, and transmits condition information to machinery monitoring systems.
The 330905-08-13-10-12-05 belongs to the 3300 XL 8 mm Proximity Probe Series. It is designed for applications requiring high accuracy, reliable signal performance, compact installation, and long-term continuous operation.
The probe is widely used in critical rotating machinery, including:
- Steam turbines

3. Product Structure and Working Principle
The 330905-08-13-10-12-05 proximity probe consists of a sensing tip, probe body, threaded mounting section, internal sensing coil, and electrical connector.
The sensing tip is the key measurement component. During operation, it generates a high-frequency electromagnetic field toward the rotating shaft surface.
When the shaft moves due to operating conditions, the distance between the probe tip and the shaft changes. The electromagnetic field changes accordingly, and the probe converts this variation into a proportional electrical output signal.
The monitoring system analyzes the signal to determine the current operating condition of the rotating machine.
The probe can detect mechanical changes caused by:
- Rotor imbalance
- Shaft misalignment
- Bearing degradation
- Thermal expansion
- Mechanical looseness
- Rotor instability
The complete monitoring system normally consists of:
- Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
The non-contact measurement design prevents physical wear between the sensor and the rotating shaft, ensuring stable operation during long-term service.
