Bently Nevada 330905-05-10-10-12-05 Proximity Probe Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-05-10-10-12-05 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 changes, and relative movement between the rotating shaft and machine housing.
This model uses advanced eddy current sensing technology, which provides accurate non-contact measurement. The probe detects changes in the distance between the probe tip and the conductive shaft surface and converts these changes into electrical signals for machinery monitoring and protection systems.

3. Product Structure and Operating Principle
The 330905-05-10-10-12-05 proximity probe consists of a sensing tip, probe body, mounting thread, internal coil assembly, and electrical connector.
The sensing tip is the core measurement component. During operation, it generates a high-frequency electromagnetic field directed toward the rotating shaft surface.
When the shaft moves due to vibration, thermal expansion, mechanical loading, or rotor movement, the distance between the shaft and the probe changes. These changes affect the electromagnetic field strength and are converted into proportional electrical signals.
The monitoring system receives these signals and analyzes the shaft movement condition.
The complete monitoring system normally contains:
- Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
This combination allows continuous measurement of machine operating conditions.
Because the measurement method does not require physical contact with the shaft, the probe avoids mechanical wear and maintains stable performance during long-term operation.
