Bently Nevada 330905-08-13-10-02-05 Proximity Probe Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-08-13-10-02-05 is a precision 3300 XL 8 mm Proximity Probe designed for monitoring the operating condition of critical rotating machinery. It is mainly used to measure shaft vibration, radial displacement, axial position movement, and relative shaft motion in industrial equipment.
The product adopts eddy current sensing technology, which enables accurate non-contact measurement between the probe tip and the rotating shaft surface. When the shaft position changes during operation, the probe detects the variation in distance and converts the displacement into an electrical signal for machinery monitoring and protection systems.
The 330905-08-13-10-02-05 belongs to the 3300 XL 8 mm Proximity Probe Series. It is designed for applications requiring stable measurement performance, high reliability, compact installation, and continuous operation under industrial conditions.
The probe is widely used in important rotating equipment, including:
- Steam turbines
- Gas turbines
- Centrifugal compressors
- Generators
- Pumps
- Motors
- Turbo machinery systems
By continuously measuring shaft movement and vibration behavior, the product provides important information for equipment condition evaluation, early fault detection, and predictive maintenance.
The 330905-08-13-10-02-05 configuration provides a practical solution for industrial users requiring reliable shaft displacement measurement and compatibility with machinery monitoring systems.

3. Product Structure and Working Principle
The 330905-08-13-10-02-05 proximity probe consists of a sensing tip, probe body, mounting thread, internal sensing coil, and electrical connector.
The sensing tip is the core measurement element. During operation, it creates a high-frequency electromagnetic field directed toward the rotating shaft.
When the shaft moves due to mechanical conditions, the distance between the shaft surface and the probe tip changes. These changes affect the electromagnetic field, and the probe converts this variation into a proportional electrical signal.
The monitoring system receives this signal and analyzes the condition of the machine.
The probe can detect changes caused by:
- Rotor imbalance
- Shaft misalignment
- Bearing degradation
- Thermal expansion
- Mechanical looseness
- Abnormal rotor movement
The complete monitoring system normally includes:
- Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
The non-contact design eliminates physical contact between the sensor and the rotating shaft, reducing wear and improving measurement stability.
